SOURCE: Epson Aculaser C900 photoconductor inserted incorrectly message after changing

Hey Marts Try this: Remove the PCU and the Transfer belt assy's Look inside the machine to the back, top left where you will see the cam as detailed in the picture below Open the right door and you will see a Green Wheel about half way down on the back side. Turn this wheel so the cam inside turns untill it is about 100 - 110 degrees further round (anti clockwise) than it is in the picture - basically make it go as far round anti clockwise as it will go Now try reinserting the TFB and PCU assy's in turn. You do not need to insert the 2 big silver screws that hold these units in place Close her up and see how you get on. If this has no effect, let me know and I will see what else you can do.

SOURCE: Black Cartridge just changed, but still says K-toner low

The only way to clear the message is to wait until the the display shows XXXX Toner Out, then change the cartridge and the message will clear itself.

Hi there

This suggests a fuser error. This is the hot unit at the rear top of the machine.

Steps are as follows:-

1. Open COVER FUSER.
2. Draw out the COVER RH boss from the hole on COVER FUSER while pushing
COVER RH outward, and remove COVER FUSER.

After removal check coninuity across heater lamp amd thermistor terminals. If either shows anyhing more than 13 Ohms then you need to replace your fuser unit.

Anything more than that requires hands on technical expertise.

Good luck

SOURCE: Aculaser C2600 "clean sensor" message

This is a common characteristic which arises from using improperly remanufactured toner cartridges.
Otherwise it is a bad Epson original one - which is highly unusual!

When the C2600 runs through its calibration it prints strips of each colour on the transfer belt which are sensed for density. You will get a "clean sensor message" if the reading for any of the strips drops below a certain value.

The first thing to do is to depress the clean sensor lever behind the front cover several times . If that doesn't fix it I would advise you to remove each cartridge in turn (go to reset menu and scroll down to change toner) and inspect the toner on the surface of the roller. If there is any form of "sheen" then you'll need to replace the cartridge.

It is possible to adjust the doctor blade if you know what you're doing but be careful as there are shims on each side. Loosening and moving the blade bar towards the roller slightly, refixing and then turning the side cog to rotate the roller can sometimes resolve problem. Not a good idea really unless you're in an emergency.
There are some good remanufactured cartridges and bad ones. If you want to avoid this buy genuine Epson cartridges - I know they're expensive but what does the down time cost!

SOURCE: epson aculaser c1100 not printing right hand edge

The problem may well be that the drum needs cleaning. There is a plastic flap on the rhs of the machine. Open that and you can pull a long lever out. You also need to let down the front cover and pull out the lever on the right hand edge that faces you. Then extend the long lever at the side as far as it can go and push it in and out a few times. This should solve the problem. Put the front lever back and close the cover. It took me ages to find this - Epson are not good at highlighting it,.

Ghost image on Epson Acculaser C4000


Ghosting can be caused by several components: 2nd BTR transfer roller, Photoconductor Unit (PCU) or the Fuser unit. The most likely is the PCU contacts being dirty, caused by toner getting between them. Open the front of the printer (cover B) and lift out the photoconductor. Clean all of the metal contacts down the sides of the PCU with a cloth and wipe out any loose toner from inside the printer and give the contacts inside the printer on the R/H side a good clean. Replace the PCU and close the front cover.
Hopefully all will now be well, if not open cover A and clean the transfer roller on the inside of the cover. If problem persists you will need to get a Tech out to look further as without seeing the printer it is pretty hard to diagnose.
Good luck.

Epson Aculaser C1100 - E511


The E511 error comes when you power up the printer. The noise of the "warm up" is the black rubber transfer belt on the Photo Conductor Unit spinning through one rev to check for a little silver square on the edge of the belt. You can turn the belt manually to see this square.

If this square is not found, Epson will tell you to throw away an otherwise fine PCU.
Solution:
a) Remove PCU and check the transfer belt for the square. Clean WITHOUT alcohol.
b) check the sensor that reads this square - a small black oblong "camera" in the heart of the printer on the LHS. Clean.
c) If the square is damaged, replace with a piece of tin foil. Superglue on carefully, making sure all the edges are glued but not your fingers!

You don't need to put the new square in exactly the same place, just above or below on the belt is fine.

What is service E524


This means the output value of the ADC sensor is below the required value.

Possible parts that caused the error:
  • Photoconductor Unit
  • SENSOR ASSY ADC
  • Toner Cartridge K
  • Toner Cartridge Y
  • Toner Cartridge M
  • Toner Cartridge C
  • HARNESS ASSY ADC
  • SENSOR HUM & TEMP
  • HARNESS ASSY MAIN
  • ROS ASSY
  • PWBA MCU
  • LV/HVPS
Head for the ADC Sensor assy first. It's the sensor assembly in the rear door below the fuser unit. Check that it is clean and clear of bits of paper etc.

try a replacement Photo Conductor Unit - even an old worn out one will do, just to see if the error clears. If it does you know your PCU needs replaced.

Much more than this and you will need an engineer to look at it as The High and Low voltage systems are not to be toyed with. Similarly the ROS unit if dead will mean the machine is beyond economical repair.
