Our company recently bought a Ricoh Aficio AP3800C but when we print the pages come out with 2 or 3 black marks on the top of the page - the marks look a bit messy but are no more than 3/4 mm in width. What do we do to get rid of these marks?
Another option if cash is a problem is to take the Black pcu out (top left hand side of machine) and clean the charge roller. This is the black rubber roller that sits above the Drum. Simply turn the pcu over, and use only ****water and a soft cloth to clean the charge roller. It is important not to use any chemicals etc unless you know what you are doing as the drum surface can be damaged easily. If you are feeling really technical you can take the 2 screws out of the front of the unit, pull off the cover and the drum can be prised out to make the charge roller more accessable. Hope this helps.

sounds to me like there is damage to the charge roller in the black pcu. these can be dissasembled and the charge roller inspected/cleaned but the blk drum units are inexpensive enough its probally just better to replace it
Check the little black piece of plastic that senses the printed page exiting the machine. Our sensor was stuck and I was getting the same message (an similar Ricoh product). When I gently reset the black piece to center, moving freely, printing worked again. I think the sensor got jammed up when we were trying to remove a bad paper misfeed.
Ricoh manuals very confusing on this error message. They refer to standard tray, tray one, etc. without being clear whether it's a paper feed tray or the so-called "standard OUTPUT tray." The output is not really a tray, it's just the depression where your sheet lands after printing. I wrenched on the paper feed trays and their settings for an hour before I figured out they meant OUTPUT.
If there is toner in the cart but not getting onto the page, the most likely cause is that the toner delivery tube is blocked. You can try removing the unit and vacuuming out the supply line to remove any lumps that may be lodged and then run the forced toner supply in the Service Mode.
Hi there the smudges are most likely down to the black PCU (Drum Unit) and following are the reasons for the two fault caode you have given me.
