Ricoh 1018/2018 PCQ

[copycart]

I have a 2018 that when making copies from the glass, I get a dark sky shot like band on the rear side of the copy. I have seen this problem on the 1018 copiers and have never been able to figure out the cause

Check the drum. The photo conductive coating could be worn off or the surface could be coated with toner.

Is it only from the the glass?
How about when you print a counter sheet or use the adf?

Could you share a picture? I don't think I've ever seen that exact problem before. In the mean time, you might want to replace the transfer roller. At least without actual troubleshooting information that's what I'd try next. But that is just an uninformed guess.

Pull the PCU and stretch the springs on the back wall of the machine and clean the contacts on the PCU. That will take care of that 2 inch band if the drum is coating not worn off. Mongo

As I understand well, the back side of a single printout is black.
If this is so => transfer problem
which can be caused by a bad pcu (worn?) OR a bad transfer roller position or the grounding of it.
Also if many jams happens the transfer roller get dirty quickly and causing this problem to.

It's coming from the transfer roller. You can turn on transfer roller cleaning, but it's been my experience that a developer change is the only remedy for this. Be sure and set developer according to procedure.

My understanding of the term "rear side" refers to the edge of the paper that is to the rear, as opposed to the operator side, as it comes of the paper exit, not the "back" of the sheet of paper.

In the Dutch (and south Africa) language we say "achterkant" or "verso-zijde" for what is printed on the back of a duplex document. What is (are) the exact term(s) used in the English language?

If the dark band is only when copying from the glass then another possibility is that the white platen sheet is deformed/rippled or not sitting flush with the scanner surface . It will allow room light through and give you that condition. Would help to post an image and a few more details.

On the right track. It is light infiltration akin to the old Ricoh Aficio 1045 when we had to pull the entire scanner up because of poorly designed support for the scanner/df assy.
