Vertical means absolutely when talking about the copier process. Is it in the main scan or subscan direction?

What do "the main scan or subscan direction" mean?

If you were a trained Ricoh tech you would have learned that in the Copier Basic Course.

Agreed..!!!
This is NOT a forum that end users generally come to ...it's not Fixya.
It's more of a forum for technicians to talk shop...seek help with issues similar to yours etc etc.
If you're an end user then the only advice that you should be receiving is to seek out a qualified technician.

Appears to be an issue with K PDCU.

The model was released in 2006. I would recommend a replacement....13 years is a little old for those machines. I'm not certain WHEN... but parts availability WILL be an issue sooner rather than later. Once you get a part listed as "No longer available" that machine will be dead in the water.

In the meantime, if you want to have fun disassembling the black photoconductor unit and cleaning it, it will certainly not worsen the quality ..
