Misfeeds and how to get Xerox parts
Problem: Not pulling paper from the tray.
Cause: A broken drive gear attached to the metal shaft that the primary feed tires are attached to.
Solution: Remove the back panel and the gear package behind it. There is a black plastic gear, which can be taken out by hand at this point. Xerox can be reached by their 800 number and then ask for parts. They will look it up in the parts book if you describe it properly. It's about 8 dollars plus shipping. You may also obtain parts from other vendors. See Smarka’s banner ads and search listings.
Workcenter 450cp multifunction
Feeds more than one sheet of paper, replace separator pad, you can use rubber pad material that you can get at a local hardware store, like OSH. So far this has worked for me.
XC 830, 1045, 1255
These machines can be modified to take the Sharp ZT-81TD1 toner cartridges. Remove the cartridge and look at the back of the cavity where it goes. You will see a black plastic guide with an oval hole in it. This determines which cartridge will fit in the machine. If you look at the rear frame of the Xerox and the Sharp cartridge, you will notice the long oval extension is in a slightly different location. If you remove the guide, the Sharp toner cart. will go right in. You need a Long screw- driver, a springhook, a flashlight, and three hands to remove it. Actually it isn't that hard, use the springhook to pull the little hook at the bottom towards you while lifting up on the guide with the screwdriver and it will pop right out. Sorry, be sure to remove the drum also before you try this. These cartridges are nice to recharge and work very well. We sell a lot of them every month for $75 and it costs about $15 to recharge them. Be careful not to mix up the Sharp and Xerox carts. if you haven't modified the machines.
1012/5012 SERIES
UNEVEN DENSITY
When troubleshooting varying density of the copy on the 1012 family don't be to fast to jump into the Dev assembly. Check the copy with and without A/E. A bad illumination sensor or pwb will cause a similar strobing.
BANDING AND UNEVEN EXPOSURE
This is probably caused by dead mag roller. Try cleaning and sanding the mag roller otherwise it's a new dev tank.
CARTRIDGE FAILURE
Do you have a 1012 family copier that is prematurly going through cartridges because of scratches? The problem could be solved for as little as $.65. On the paper chute assemlby are two white delrin spacers one on each end. When paper jams under the cartridge these spacers prevent the baffle from contacting the drum. If they are worn or lost replace them part # 14P62282.
CARTRIDGE FAILURE
The inter image lamp in this model is critical. If if is bad or the pwb is bad a Copy Cartridge can fill in just a few hundred copies. The 1012 can have two different interimage lamps most easily detected by counting the connector pins either 3 or 4.
FEED ROLLERS
1012.5012,5014 feed tires. Remove the rubber feed from the assembly clean off old glue and take a pair of feed tires part number 20E4580 from the 5018 family. These will fit with slight modification the tabs on the ends will have to be cut off. Glue the new feed tires into the old assembly. These tires are available from other vendors than Xerox and run approx. $7.50 a pair.
JAMMING
If you get jamming between the feed tires and the registration roller, you may just need to add tension to the springs that add pressure to the small white rollers in the same area. Just reach in and bend them downward so they make more solid contact with the rollers underneath.
1012/5011/12/14 paper jams
Problem: If you are experiencing frequent paper jams at the registration gate, the problem may be very simple.
Solution: Check to see if the gate solenoid is working (diagnostic code 83). If so, check the magnet of the registration switch actuator. This is at the end of the switch actuator rod on the inboard end of the baffle. It is very common for the magnet to become impacted with toner which, has leaked from the back of the toner hopper. Clean away the toner and the solenoid should work when the switch is actuated.
1025/1038
Main Drive Motor
It is a good practice to remove the main drive motor frequently and remove the gears, wash the shafts and re-lube the gears. A good lube is LOCTITE NEVR SEEZ. It is a high temp grease that is used on threaded fasteners in areas exposed to high temperatures. It lasts longer in the gears than any other lube that I have tried.
NOISE
Problem: Loud screaching sound. Sounds like it comes from the developer unit.
Solution: (This one took me months to find) The main metal drive gear located in the center rear of the machine about 2.5" in diameter has a bushing going through the frame. I cleaned it and applied a little oil and it was fully resolved. Noises like this are hard to find because it is connected directly through the frame of the machine and hard to isolate.
INTERMITTENT / VARYING REGISTRATION
Check the lamp carraige home sensor - it may need cleaning or shifting. There is a small amount of adjustment on the sensor, but you can also install a washer or two as spacers.
COPY QUALITY - SLUGGISH OPERATION
Remove the main motor (4 screws behind main PWB) and lube two gears & shafts. Also check the registration gate shaft bushings for contamination by dev and crud.
ELECTRICAL
Intermittent display, blank display, frequently blown low voltage power supplies. This usually occurs on adh and sadh machines, but I have seen it on flat top also. the left rear of the top panel will interfere with the pj on the relay circuit board located behind the main circuit board. This interference will crack the solder connection on one of the pins usually the first one on the machines right. When having this problem check this connection closely. To repair resolder connection and adjust the left top cover support to its maxium position.
COPY QUALITY
Light copies.Very common on this machine. Many causes. Here is a list of things to check:
Check the dev bias lead where it plugs in to the frame of the copier. This is a very flimsy contact and can easily come off or break.
Make sure that the toner is not clumped up in one side of the toner hopper. The large spring inside the hopper that stirs the toner sometimes comes loose from the gear that turns it. This happens when the user shakes the top of the unit from side to side too violently. (It's supposed to be shaken to help break up the toner, but this sometimes backfires and dislodges it, preventing normal stirring.) Reseat the spring and refill the hopper.
Generic toner. Some of the less expensive brands have been known to cause light CQ. This machine is particularly sensitive. You might suggest to your customer that they use OEM toner and developer.
Broken gear. There is a small gear on the rear of the DV unit that frequently cracks and needs to be replaced.
Dispensation setting. Inside the door on the upper right of the machine there is a tone-up button. Above this is a knob for setting the toner dispensation rate. (This knob may be covered by a plastic cover held on by a plastic screw. Take this cover off and throw it away.) Make sure that this knob is set to the maximum.(Clockwise).
Toner hopper closed. Under the hopper is a lever type device that's shaped like a backwards "L". This opens and closes the toner "valve" for hopper removal. Frequently it gets moved and needs to be replaced into the down position. This opens up the opening and allows toner to flow into the DV unit.
NOISE
Squeaking. The main drive motor wears out and squeaks very loudly. This is very common. Replace the motor.
Chatter. The gears that transmit drive from the main drive motor to the fuser section wear out frequently and need to be replaced
Grinding. Developer falls into the feed shaft assembly underneath (and attatched to) the DV unit. Remove the guide, shaft, and bushings and clean them well before reinstalling them.
ELECTRICAL
Intermittent failure. Blinking display. The low voltage power supply fails regularly on this machine. It is located in the rear left hand side of the machine as viewed from the rear.(The big silver thing) Replace.
1040
COPY QUALITY
Background or black copies. Dim exposure lamp.There is a fuse inside the lamp ballast (located to the left of the HVPS inside the front of the machine) that blows occasionally. Replace.
Black copies. Exposure lamp inoperative. The ribbon cable that supplies the lamp breaks open from being flexed with every scan. Replace.
JAMMING
The density sensor (under the drum) also doubles as a paper path sensor. Toner frequently clogs it up and it can't see the paper. This usually results in code 8-12 jams and 1/2 copies being output to the tray. Just clean the sensor and run routine 9-71. This will set the reference for a clean sensor against a toner patch on the drum. If you have trouble setting this routine, you may have to adjust the ADC pot on the main board and try it again. Sometimes this sensor goes bad and needs to be repaired or replaced. There aren't many components on it so you can usually repair it fairly easily.
ADF MULTIFEEDS
The separation pads under the feed paddles (Xerox calls them Retard Pads) wear and need to be replaced. You can extend the life of these pads by placing a small shim under each one, (a small piece of folded paper will work). Clean the pads with alcohol or Fedron. (Or whatever you normally use on rollers and such.)
ADF MISFEEDS
Make sure that the small feet on the front of the ADF stick out 10.5 mm. These determine how high the front of the feeder rests and therefore the document belt pressure.
FUSER JAMS
The fuser on this machine is prone to getting air bubbles in the lube line. This causes the wick to get dry and subsequently the toner sticks to the roller instead of the paper. Check for air bubbles and purge them out by loosening the cap on the end of the wick manifold (keeping it higher than the rest of the fuser so the air will go out of it) and squeezing lube through the line until you see lube come out of the loose cap. Tighten the cap. You may need to clean the wick and manually put some lube on it to get it started.
1045/1048
ELECTRICAL
No power. Shuts off. The interlock relay (located on the rear lower left) contacts may be corroded and need to be filed slightly or cleaned. It's fairly easy to take apart and clean but make sure that you reassemble it the way it was. (DUH)
1050
ELECTRICAL
Erratic operation. Blinking display. The regulator board (located in the rear of the machine near the output side about halfway down the machine) is known to be bad. Xerox came out with a new style board but not all of them have been replaced. If the one on your machine is silver and blue, it's probably bad. Replace it.
COPY QUALITY
Background or black copies. Dim exposure lamp.There is a fuse inside the lamp ballast (located to the left of the HVPS inside the front of the machine) that blows occasionally. Replace.
Black copies. Exposure lamp inoperative. The ribbon cable that supplies the lamp breaks open from being flexed with every scan. Replace.
FUSER JAMS
The fuser on this machine is prone to getting air bubbles in the lube line. This causes the wick to get dry and subsequently the toner sticks to the roller instead of the paper. Check for air bubbles and purge them out by loosening the cap on the end of the wick manifold (keeping it higher than the rest of the fuser so the air will go out of it) and squeezing lube through the line until you see lube come out of the loose cap. Tighten the cap. You may need to clean the wick and manually put some lube on it to get it started.
TRAYS 1 &2 STUCK
There is a clutch assembly that is attatched to these trays via a cable in the inside rear of the machine called the nip clutch assembly. This is one of the strangest systems that I have ever seen. When these clutches bind, you are best off replacing them, but if you can't you can always clean them and try to adjust them. They each have a small screw to adjust but there's not really a specific way to do the adjustment, so it's basically just trial and error.
1065/5065
COPY QUALITY
Light copies - 924 codes.
The 924 code is light copy code. when trouble shooting this code or similar codes always start at the weakest link. The dry ink auger and it's plastic drive shaft. I know it's a messy job but someone has to do it. Pull the dry ink dispenser and check to see if that auger is twisted or bound up. This auger shaft breaks quite often. It can cause 970 codes and call for 5970 shutdowns by causing developer bead carryover, as well as a wide range of 900 series codes from. The 1065 is amazing It will produce jet black copies from starved developer. The only way to know for sure is to remove the auger.
COPY QUALITY
1065 blank trail edge about 1.5" to 2.5". I first run a dark dusting to see if total trail edge is blank. Usally a strip of print approx. 1 " wide will appear halfway down the 11" edge. If this occurs it is an indication that the lens shutter is binding or closing late. Check the lens solenoid and linkage for any loose hardware. Also check for the presents and condition of the orange washer on the plunger of the Solenoid. If needed the part number is 28E7491 and cost $9.65 from Xerox. This washer prevents residual magentism in the solenoid. It will cause this problem imtermittently.
COPY QUALITY
Copy quality on 1065 dark streaks or smudge. Does not move with reduction. Is not on the p/r belt during a panic stop, and is on the copy in a panic stop before it is fused. Check the black strip of mylar (paper deflector) just before the transfer dicor for traces of toner. If this gets damaged during jam clearing it may contact the p/r belt. Causing stearks, ghosting and smudging. Part # 55E4020.
1075/1090
Having trouble with H129/H132 faults? Manual will lead you in circles replacing patch generator or XER pcb or just plain dead end. Try running DC40-23 and 24. If 23 is over 40 and 24 is over 70 try running 23 again with the light shields off. Chances are good that the multipurpose lamp is burnt. Replace it and you should be good to go.
1090
GROUND STRAPS
If you are having problems with heatroll ground strap screws backing out, install your heatrolls with the ground strap on the inboard end (the end with the gear). The syntrifical force of the heatroll rotation will keep the screw from backing out and rubbing against heatroll bearing (which causes loud squeeks that customers love so much).
1090 - Using Blue Belts!
Keep the DSS CLEAN!! By reducing the DSS numbers in half. (Blue belt values) the tolerance window is also cut in half . (GAT set @ 80 to get a 190 reading on DC40-25 on the blue belt.) Any dirt contamination will reduce the value of GAT much faster, which is set @ 80 not the higher LED intensity of 185 - 195 set for brown belts. The other solution is to use the original brown belts which give a much wider tolerance window.
2510
COPY QUALITY
Have a Xerox 2510 that does not like running blues. Change the illumination sensor. It sets to the left of the document sensor.
BACKGROUND
Have a 2510 that has a black shadow of background approx. an inch wide running the full length of the drum. That repeats itself every drum revolution and lightens slightly with each rev. Try placing a strip of black electrical tape along the front edge of the plastic platen. Place it on the underside as to prevent document interference. It seems that light can leak in at certain angles. This also seems to keep the machine running cleaner.
5014
SCANNER CRASH
The optics clutch assy has a tendency to wear out. The shims wear, spacings increase, and suddenly the scan and rescan clutches try to drive simultaneously.
The factory reccomended mod involves resetting all the clutch spacings ( in true Xerox fashion ) but this only works if the assy is not worn out, which is usually the reason for the crash in the first place.
A new clutch assy is the only real answer, and these are horrendously priced where I come from. (New Zealand)
5017 Drum reset fuse board part number
Part number is 140K834750. Whole board needs to be replaced, as fuses to buy from electronic suppliers are more expensive than replacement board. (If interested, they are 22mA radial micro-fuse.)
5018
U7-1 Code
I have found out that the black strip of plastic above the erase lamp can cause an U7-1 code just cut It out and you are back in business.
5018/5028/5034
Flickering Control
Fliquering control console or Exposure lamp the 90% is the groundingproblem on the ground clip at the transfer corotron. Remember the front one.
ADF FEED ROLLERS
These can be costly to replace but can be rejuvenated with coarse emery cloth. Like the manual feed system, the ADF likes to be regularly used.
MANUAL FEED
These feed rolls have a habit of hardening when they are un-used. If you persevere with attempting to manual feed they will soften and allow paper to be fed. The trick is to use the feature regularly or not at all.
DEAD MACHINE
Go straight to LVPS located under fuser. This is a common failure and should be fairly cheap to replace. Sorry I can't offer PWB repair instructions.
FUSER WEB
These webs are identical to Canon 3825 series which are considerably cheaper.
FUSER ROLLERS
If you have trouble sourcing these rubber coated rollers, replace them with teflon coated. Your local recoating specialist should be able to help.
In some machines you may have to adjust the nip pressure to avoid creasing or other fuser problems.
FREQUENT J1 CODES
Frequent J1 codes, or J1 codes shortly after Dry Ink Cartridge has been replaced. Manual tells you to check for bridging in the dispenser and to replace auger. Before you do this remove dry ink cartridge set cartridge on a drop cloth upside down and slide off the access plate. turn the large black gear and check to see if the feed spring in the Dry Ink Cartridge turns. I have seen many bad cartridges especially in the third party and refilled cartridges. If you refill the cartridge the spring will come off if the gear is turn in the wrong direction. I have seen four bad cartridges in a row from third party supplies in one account.
P/R BELT REPLACEMENT
Something fairly new to this product is a third party blue belt. As in the case of the 1075/1090 blue belts they require a lot less light to produce the same or better copy as the OEM. So when installing one for the first time adjust the exposure lower (I have found that most machines will run at a 1 or 2 setting in P 9-62) This will save a call back for light copies and will save on toner consumption.
DH BELTS
5018, 5028, 5034 RDH and ADH feed belts become slick from wear oem recommends cleaning this belt once. After one cleaning the belt seems to cause misfeeds shorthly after cleaning (dreaded call backs). A product that I have used in the past for temporary fixes on different feed rolls and belts has been Elmer's Stix All a combination of RTV and glue. The small tube fits easily in the tool box. For best results remove the feed belt clean throughly with an alchol base cleaner. Apply a liberal amount of Stix All to the clean dry surface, allow to dry for approx 4 hours ( completely cures in 24 hours ) before use. I have found that a properly treated belt will last 50,000 copies and more. Making this more of an permanent fix than a temporary one.
ELECTRICAL
Intermittent flashing display. Spontaneous feeding or other logic problems. Try replacing the copy cartridge. There may be a problem with the photoreceptor ground inside the cartridge. You can check inside the cartridge for staples or other debris, but usually if you can sell the customer a new cartridge, that is usually best.
COPY QUALITY
Lines at the top. Poor resolution. The mirrors are held in with small plastic clips. These clips break and the fixed mirrors may not be held in firmly causing copy quality problems. If you work on this machine frequently, you might want to keep some of these handy.
Intermittent light CQ and background. Check that the block that holds the corona (or as Xerox calls them, corotrons) contacts in the front of the machine isn't broken. The mounts that hold the block onto the copy cartridge carriage sometimes crack and the ground and charge contacts can't make sufficient contact with the copy cartridge. You may be able to epoxy the parts back together, but as usual you will probably be better off just replacing the entire carriage assembly.
5028 Family
On every visit to a 5028 family mach. enter diagnostics, select code 8-62 [bypass feed "ON"], take 10/12 8.5 by 14 inch paper in your right hand, wet the other end of the paper wad with film remover, or isopropyl or other alcohol and insert the wad of paper into the by > pass feeder while hanging on to the other end. When the wad is in place push the start print button and allow the bypass feed rolls to run on the top sheet of paper that is wet with the alcohol Remove the top sheet of paper and repeat the steps again, until you can feel the increase of the pull of the feed tires on the paper. No need to take the system apart to clean the tires, and you can possibly prevent a call back for bypass misfeeds.
ADF MISFEEDS
One of the more troublesome components on the early models is the ADF Prefeed mechanism. You can groove the rollers for some quick fixes, but the real problem may be in the clutch. Remove the clutch, disassemble the gear from the main body of the clutch. Remove the snap ring that holds the metal disk onto the gear. Take a scotchbrite pad and scrub that metal disk until all the grime, rust, and residue are cleaned off. Don't use cleaners, they don't work. You can use a deoxidizer, but the disk must be clean and dry when reassembled. You'll know that the clutch is slipping because the roller beneath the stack force lever doesn't turn or the rollers are easily stopped when applying pressure to them. Clean the rollers and replace the retard pad. Finally, if all else fails, replace the prefeed module (last resort).
FUSER NOISE
Check to see if the fuser heat roll has end play. If it will move from front to rear inside of the bearings, replace the split collars. There is a metal one for the rear and a plastic one for the front. Make sure that the pressure roller has not derubberized on the rear end. Finally, adjust the load arms to specification with the parts mentioned. 12 on the rear and 15 turns down on the front. If the fuser drive gear is not worn out or dirty, you should seriously consider those split collars. The bearings usually squeak or grind, but they don't thump. If you put new collars on and you still have end play, install the bearing fallout washers on the drive gear side only. As these bad boys heat up, the frame of the fuser expands and your heat roll gets a little play in it. Installing the fallout bearing will take up the slack.
HALF RATE MIRRORS
Sometimes the half rate carriage (mirrors 2 and 3) can become loose in the plastic housings. If the plastic clips that secure the mirrors are missing, long plastic ty-wraps can be used to hold the mirrors in place. This will save you $$$ on a new half rate assembly. XEROX Models 5018,5021,5028,5034,5126,5321,5328,5334
LIGHT COPIES
If light copies are still occurring after following the
light copy rap and developer carryover rap, make sure you follow the
electrostatics rap. If this still yeilds no results, dissassemble the
developer housing and check for a clogged ink dispenser or clogged
developer housing. Some company out there is refilling ink cartridges
with straight developer. This is causing developer carryover and
ruining the developer module. After cleaning the developer and ink
dispenser, be sure to run p 9-5 tone up to refill all augers with ink.
Discard the toner cartridge and inform customer that their source for
ink should be reconsidered. Not in manual.
FEED HEAD
I encountered this problem while recycling tray 2-3 feed heads. The
feed head can be rebuilt off site for reuse to save onsite time for
those heavy queued up days. A feed head and the drawer may be out of
alignment when doing this which causes the paper to feed at a posistion
where it picks up toner from a non erased area of the PR belt. Adjust
the drawer stop screws in or out until the line is gone. This line is
often mistaken for optics skew, but it usually occurs after feed head
replacement.
U7-1
Intermittent U7-1 is usually the copy cartridge, but not always.
Checking the voltage at TP2 and PJ102-20 should give you 25vdc, but
replacing the main board may not always be the fix if you aren't getting
25vdc there. The driver board relay switch is actuated and deactuated
by a high or low from jp102-20. Replace the driver board prior to
replacing the main board. Many of the older style driver boards have
become defective due to heat. The new style board has a larger ceramic
resistor where the old one was failing. If a new driver board doesn't
cure this problem, and a new cartridge or belt yield no success, then
the problem can only be in the main board. You can always remove the
driver board if that fix doesn't work. A main board takes a little more
work to install.
FAULT CODE
Also check the pre-charge erase lamp located above the print cartridge, this will give a U7-1 code if it's open.
5028F
HEAT ROLLER REPAIR
Here is a little experimentation you can try if you are hesitant to spend the big bucks on a new heat roller when the stripper fingers wear the rubber coating off. A line will appear on the copies when the rubber coating has been worn off by the stripper fingers. Get some high temp red or white Silicone rubber sealant. Apply the sealant to the roller and smooth it out. This takes a little patience and time. Let the sealant dry before installing the roller. This works best with small nicks and cuts that aren't the result of excessive wear. Again, this is still a little experimental, so don't be disappointed if it doesn't work perfectly the first time. I have had limited success with it, but it does work when the marks or gouges are small and can be easily repaired. Best results are had when allowing the sealant to cure for a couple of hours. Reuse that roller or try to on the next machine you have to replace one. Can potentially save you $$ on parts costs.
5028, 5034,5334,5328 5626,5624,5830
SKEW
Skewing not associated with optics is caused by a worn lower baffle. If the guide ribs on the baffle are worn flat, replace it! Replace the upper baffle with the lower for even wear and correct pinch pressure. When removing the main feed assembly, be sure to clean and lubricate the tray one feed clutch and registration clutch to avoid call backs for noise.
5046
ELECTRICAL
Intermittent flashing display. Spontaneous feeding or other logic problems. In the rear of the machine on the output side, sometimes the white plastic cover over the control and driver boards comes in contact with the plug jack near the clip that holds it on. (Take a look and you'll see it if it's pressing on it) You can just cut the corner off the cover and you should be o.k.
5046/5047/5335
ROLLER RECOATING
When sending out your fuser rolls for recoat. Have the recoater use yellowish brown (Hypolon) material. It's used on the 9500 fuser roll and some third party rollers for the 1065. This material is tougher and last longer.
COPY QUALITY
Many times after the machine adjusts copy quality the copy is over exposed and over toned. The pot R134 on the Driver PWBA board under the white cover on the back panel on the left controls the exposure lamp. I have found that by adjusting the exposure the copier will run cleaner, and dev. and PRs will last longer. To adjust 1st check for 10.2 vdc at PJ2 pin 16 (connector between driver and control PWB's) Then adjust so that the .1 gray scale is slightly visible or just erased without effecting the.2. The .2 should be completely visible. I will follow the adjustment with the long setup procedure (turn on don't use reset button) and recheck. I have added this to my final check out procedure after a couple thousand copies the density does back off alittle causing a readjustment on the call.
5113
Problem: Copies are lighter on the backside. Overall copy density is weak.
Solution: Make sure the developer unit is camming in all the way towards the drum. A simply way to check is to push on the cartridge towards the drum, check to see if it moves closer, and then check copy quality. For the backside, remove the back cover and push on the rear dev. pin. If that is the problem, remove and clean the dev. cam unit. Copies are lighter on the backside. Overall copy density is weak.

5113
When doing a conversion from a Xerox 5113 to a sharp 2114, after swapping out the main board , if the adf is not detected, do simulation 26 sub code 1 and set it to 1. Also if the R/E does not work, do simulation 26 sub code 6 and
set it to 16.
5113/5114
CONSUMABLES CROSSOVER
These machines are the same as the Sharp 2114 and 2214 machines, but cannot
use the drum or toner for the Sharp version without being modified.
The toner mod is very easy, just remove the alignment peg from the front
frame of the machine which determines which toner cartridge will fit in the
machine, and now you can install the much less expensive Sharp toner in the
machine.
5205 / 5210 / 5220 / 5222
RUNS CONTINUOUSLY
Machine sits idle when print is pressed (may be clicking)... If the toner light is not on but the machine sits idle and continues running, the machine may simply be looking for toner. Sometimes it takes a long time before the toner light actually comes on.
TONER LIGHT
Toner light stays on after new cartridge is installed... After the machine is finished cycling, if it still calls for toner, turn the power off and back on for the second cycling. New toner cartridges contain fresh developer which often reequires more toner. This is true of OEM as well as reconditioned cartridges.
5307
L code
The L code on this machine does not always mean a scanner clutch problem. The main board will cause this error code also.
5314
EDGE ERASE
The manual is slightly flawed here. There is an extreme caution that
needs to be inserted. When adjusting the edge erase on the copy
cartridge charge scorotron, you must remove it. When reinstalling it,
make sure that it is put together correctly. Removing the front cover
to detach the scorotron causes the toner auger gear system on the
cartridge to become loosened also. Reinstalling the scorotron without
ensuring that all parts are fitted can result in gear breakage within
the auger assembly. End result is new cartridge due to binding and
ratcheting noise from broken auger.
5312/5313/5314
MULTIFEEDING
Multisheet feeds can be prevented by installing the paper guide blocks.
As paper is fed, the paper guides can slip until the paper guides do not
touch the paper in the tray. In addition to the paper guide blocks,
install a buckle pad on the side edge paper guide near the rear of the
guide. The velcro like pad can create enough friction to hold down
sheets below the top sheet without causing misfeeds. The part number
can be found in the 5328 or 5028F manuals. Inexpensive fix not found or
prescribed in the manual.
NOISE
Squeaking noise is caused by a rubber tube on a lever in the back of the
developer module. The rubber tube is rubbing against the developer
housing. The lever may actuate the metering blade as the gears rotate.
Use some kynar powder or a very small drop of 70p95 turbine oil on the
rubber tube to lubricate it. Inexpensive fix not found in manual.
BROKEN GEARS
Broken gears on registration roll. The corotron was not seated
properly. when removing and cleaning the corotron, be very sure that the
rear end of the corotron is seated. The gears which transfer drive to
the registration roll will strip if the corotron is not seated.
NOISE
A very loud grinding noise will occur if the copy cartridge toner auger
becomes disengaged or clogged with toner. If you are brave and can be
certain of not causing a mess, you can disassemble and clean.
Otherwise the noise is fixed by replacing the cartridge.
OPTICS SKEW
The optics on these bad boys can be very tricky. The rear cable is
often out of adjustment. The baseline procedure for the optics in the
manual says to ensure the cable eyelet is secured in the bracket. Very
often, this cable eyelet is not secured. After loosening the bracket
and installing it through the eyelet, some adjustment to the full rate
carriage may be necessary. The manual takes you through a rather
tedious task of loosening things you shouldn't mess with. Use the two
5mm allens through the frame to half rate carriage and making sure they
are perpendicular, loosen the cable clamps on the full rate carriage and
adjust until the full rate carriage tabs contact the allen wrenches.
Tighten and check. Readjust as needed. Loosening the pulleys on the
shaft is not necessary and will only make things worse.
5318 / 5320 / 5322
H6-2 CODE
A recently produced retrofit package has made the ADF/DM LVPS obsolete
in the 5320 and 5318. A wiring harness eliminates PS13 in both of these
models. As of Feb. 1997, the ADF/DM LVPS has been eliminated from the
5322 also. The difference is that the wiring harness for the 5320 and
5318 will not work. A new LVPS to replace the PS12 processor LVPS must
be ordered. The new LVPS kit will eliminate PS13 and replace PS12 with
a more robust Power output that will operate duplex, HC feeder, and ADF,
in addition to the other devices in the processor that required DC voltages.
An error code of H6-2 will lead you to replace PS13. The display says
that the ADF needs service. The error code is H6-2. The RAP will
instruct you to ultimately replace the console, the main board, or the
ADF board. This is erroneous. The reason the ADF is not functional is
that there isn't 24VDC coming from PS13. This problem has been known
for some time now, but the latest manuals do not reflect the changes.
5328
JAMS
Paper jams when tray 2 is nearly empty. The cause is a bad spring
beneath the tray plate. Replace the spring. You may also need to
replace the front paper guide and retard pad. The 5328 front guide is
not spared. The 5028 front guide works just fine. Be sure that a
buckle pad is installed and that the pinch rollers have good tension on
the take away roll (all three). This problem is characterized by the
front lead edge corner becoming folded over. The paper is getting stuck
beneath the snubber because the spring tension is too great. Other
jamming problems will not have the corner of the paper folded over like
this one. This problem is not described or prescribed in the manual.
5328 5334
I work in Xerox and all the Web's in 5018 & 5328 or 5334 are the same. The only difference was that 53's web's had more oil than the 50's fam. But not now.....
PRESSURE ROLLER
Both rollers are different than 5018's. Really. Pressure roller is different-and does not last long-causes wrinkling on any size paper, especially longer ones. Heat roller dimentions same, coating material different. Don't know yet if 5018 HR works well enough.
WRINKLING
Experiencing paper wrinkling only at the Fuser Assembly. Discuss matter with an authorized Xerox Agent. Found that the Fuser Roller , Fuser Web Material, Pressure Roller for a Xerox 5018/5028/5034 are not the same as a Xerox 5328, The Xerox 5328 Fuser Roller, and Pressure Roller are Slightly less in diameter than the Xerox 5018/5028/5034 along with the Fuser Web Material the shaft will not fit the Xerox 5328 Plastic shaft. Caution be certain you get the correct part's for the Xerox 5328, The only source available for these part's were Xerox Themselves, Believe me I've checked around and no luck. You'll also Experience a wavy effect on the paper as well.
WRINKLING
Wrinkling of legal size paper can be cured by either replacing the
pressure roll pn 22k48610, or adding a fallout washer to the heat roll
on the gear side only. Check the fuser or heat roll for endplay. If
movement is found, add washers until movement is minimized. Not in the
manual. Part number can be found in 5028F manuals.
DELETIONSFlame type deletions not associated with copy cartridge. The pressure
roll and heat roll should be replaced. Some of them are found to be
slightly out of round or will have uneven surfaces that will cause poor
fusing. Excess ink usually is removed by the web. Look closely at the
web material for excess ink. A dark colored material indicates poor
fusing. Not in the manual.
5328, 5321, 5334, 5021 Unified drive
NOISE
Knocking noise frequently occurring. Clean the exhaust fan area, fuser drive gear, and any toner buildup with film remover. Replace the drive belt if worn. Increase the tension on the idler roller by moving the spring to the top of the mount from its slot in the mount. Install the contamination filter in the exhaust fan to catch excess contamination. This filter is often referred to as the Ozone filter. The optics filter
and ozone filter are two different types. Ozone filters should be replaced as often as a copy cartridge is rebuilt or replaced.
Supplemental tip Re: Unified Drive: The tip about the ozone filter is incorrect. The only time the ozone filter should be used is when the customer complains of an ozone smell.
5334
COPY QUALITY
Blurred lead edge of copies on the standard test pattern. Check the
tension of the lamp power cable. A taught cable will cause the half
rate carriage to bind at the beginning of scan. Pull the cable gently
at the end closes to the drive motor. The cable should sag slightly
without causing interference with the carriages. Not in manual.
U9 CODES
The 5334 came out with a new style optics fan. It isn't better than the
old style. It will appear to work fine when you check it, but during
stressful operation, the fan will lock up and the overheat fuse will
blow. Replacing the fuse only will bring you back again. Orde
JAMMING
Tray 3 or duplex jamming. As found in the 5034, the tray three retard
pad and feed roller become contaminated with fuser oil causing misfeeds
or multifeeds when duplexing. Replacing the feed roller and retard pad
are Xerox manual fixes. The same retard pad feed roll problem is
occuring in the 5334. The 5334 now has a belt to replace the roll, but
the retard pad is still becoming contaminated. Clean the feed belt with
film remover and replace the retard pad. Cleaning the retard pad lasts
about a day. The HFSI maximum feeds is not being reached for this part.
5614 SDF
This machine is identical to the Sharp version (don't know the model).
The SDF works intermittenly or not at all. The wiring harness that
controls the clutch for the feed roll runs beneath the motor. Remove
the motor and check the wiring for pinched wires. Replace the wiring
harness or splice the wires (brave souls only), and then add black
electrical tape to the wiring harness until the tape covers the wires
beneath the motor. This makes the motor more difficult to install, but
it works. This is not in the manual.
5614
E-1 CODE
E-1 paper stops at fuser exit switch. Problem can be one of three things: Main board, switch, or wiring. Enter 7-1 in diagnostics and actuate switch. If display shows actuation, replace the board. If display doesn't show that switch is being actuated, disconnect the switch and check continuity from the switch to the main board and CNH 9 and CNA 26 and CNA 16 If there is no continuity, through any of the three wires, check the wiring for an open. I have found that this wire runs behind the LVPS and opening and closing the clamshell eventually pinches the wires in half. Repair the wire. Replace the switch if all wiring is good.
FLASHING EXPOSURE LAMP
The problem shows up as dark background bands. If the lamp is burned, replace the lamp. When replacing the lamp or fixing the problem, bend the metal contact on the rear end of the lamp so that it is extremely tight. The metal contact is sometimes slightly larger than the hole in the ceramic insulator of the exposure lamp. You might try filing the contact point so that it is a little smaller and more pointed allowing it to fit into the end of the lamp to make contact. Before performing any maintenance on the optics be sure that the machine is turned off and unplugged. There is live voltage in the lamp circuit with the machine plugged in.
TONER
Sharp 2114 toner fits Xerox 5614 machine perfectly but Xerox sells this toner (same toner) for 3 times as much.
5624
BINDING CLUTCHES
Some of these machines are being shipped with a green grease on the
clutches. I think this was initally done to prevent rust while in
storage or shipping. Remove the paper tray drawer, and tray two /three
feed head making sure you hold down the release lever. Remove the
clutches and clean them with film remover. Reassemble and lubricate
with a very very light coat of 70p95 turbin oil. Excess oil will
collect paper dust and you will get called back in time.
Xerox 7041/7042
*NOTE* This can only work on the 7042 machine *NOTE*Skewed prints or sometimes even skewed feed caused by Laser Assy. There is a foam pad on the bottom of the Laser Assy. that will begin to rot and soften with age. Before replacing the rubber/metal rollers, try taken the foam pad off if it feels softer on the outboard side. As it rots and it softens, it will cause uneven pressure in that area and may cause the Laser Assy. to be out of level ever so slightly. Simply pull it off and use Scotch Brite to remove excess and try it out. It has worked for me a few times. You cannot remove the pad on the 7041!!! It is there for as a fix from the factory, but on the 7042 it is optional.
Sharp Z800/Xerox XC 800 series
Doc. feed jams
Having consistent doc feed jams on any of these series machines. Check the clutch dog arm (plastic) in the clutch assembly. The arm is mounted on a plastic pin, which breaks and leaves the arm dangling. You can remove the assembly and replace the broken pin with a small sheet metal screw. Works good as new and probably won't break again.
