Black band on Copy from Aficio 1022

[Gab]

I have a vintage Ricoh 1022 which has started to put a thick black band across the copy. How do I cure this please?

Problem with drum. Disasseble drum unit ,remove opc drum and then clear at the area of the coaxial axis .Perhaps stuck some dirts .
Test it.
If it doesn;t work. Check opc drum surface at the area that print the dark line. if it scratched replace drum unit else replace blade.

sounds more like a PCR

In the sample do you see the residual image of the butterfly wing? I'm guessing thats a drum diameter. If I had Adobe Reader open on my PC I could measure.

I'm going to guess that it's a combination of primary roller (focusing charge in that area), and drum blade (unable to clean off the resulting heavy band of toner. Regardless, you'll need a new drum unit. =^..^=

Clean the PCR roller

"VINTAGE", you philistine!!!

Sounds logical.

Thank you for all the quick and helpful answers.
1) with multiple copies, the band stayed in the same place and the positions of the variations in density of the black band were largely consistent between copies.
2) it is long edge feeding
3) the mark does show on the counter page
4) there is a corresponding mark around the drum
5) the photoconductor unit was replaced 5 years ago with a new unit type 1027 and has only done about 2000 copies since then so should still be in good condition. Total print copies now about 140,000.
It is an old machine. I bought it second hand about 13 years ago for my business and have been retired for the last 11 years so it gets only minimal use as a copier and PC printer.
I will take your collective advice that it is probably the cleaning blade or charge roller and will try to open it up myself. I found a video on youtube that shows how to do it - Replacing drum charging roller cleaning blade RICOH MP 1600 2000 2352 2510 2550 2851 2852 3010 3350 - YouTube

Nice Yuck Tube video, Too bad it is for the wrong model. It does not show how to disassemble a Type 1027 PCU. Have fun finding a cleaning blade and charge roller.

It should be PCU/PCU blade or PCR.
Given the width of the band it is unlikely a fuser failure.

After 5 years that cleaning blade with be more yellow than Big Bird with jaundice. Just replace the PCU, problem solved.

it seems the typical defect, when a small piece of paper is stuck between the cleaning blade and the drum
