Question about Epson AcuLaser C4000 Printer
I've replaced the transfer unit but the mesasge is still there. The sensor is clean and functioning correctly (verified with a test meter on the contacts), and the new transfer unit window is clean.
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.

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.

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.

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!

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,.
