The belt on the secondary transfer unit keeps sliding down, causes CQ problems. Disassembled and repaired, slid down again after 20 copies. Has anyone seen/fixed this without replacing the unit.

Thanks in advance.

Unfortunately, once the belt itself has stretched a bit, there is little you can do other than replacing it.

The belt is the same as the belt for a 850 if that helps any. The assembly shows a different part # but the belt is the same. I have some used ones (850) if it helps you any.

Thanks, will order.
