color registration problem TA-5550ci

[kaborwen]

I have color registration proble with TA-5550ci. I do Auto and manuel color registration, but it's steel the same. When I make around 20 000 copies, it's goes from bad to worse. It's only the yellow color doing this problem. See the attachments. Help please!

Replace the Yellow Drum. Maybe it's not rotating properly.

Update firmware , then redo color reg. If this still doesn't work , most likely its the yellow scanner ass'y. Had a couple of boxes that refused to maintain color reg for a single color. In all cases it turned out to be the scanner assy for that color.
Good luck.
