Sounds like either the dev unit has a problem with the drum spacers and/or the transfer roller is worn out, or the grid/charge can is dirty.
Can you see the lines on the drum? Can you post a scan of the problem print/copy?

The reason the A4R copy/prints are clean is that the paper position is then in the middle of the feed path and A4C is using all the area therefore any marks at the top and bottom of the paper will show up.

Have you checked the mylar strips on the developer roller. Also check the dev roller spacers. Is it a solid line or broken up and wavy?

Transfe roller should be changed at 150k. The white horns that run on the drum wear and then the unit can damage the drum.
