Konica Minolta c458

LEGEND!! Replaced the drive assy and the machine is working fine, thanks for your all your input guys!

Glad I could help and you got it fixed!

Then, this is most likely your problem since the machine I fixed had the exact same symptoms.


If you don't want to spring for the whole paper feed assy, the parts I used to repair the one that failed (so we would have a spare replacement unit available) are:

A79J223101
A79J226200
A79J226301

Thanks srvctec!

We saw a KM bulletin that says the C458 uses some black coating on that shaft that gets rubbed off & gunks up the 1-way bearing(s) in these gears. Will affect tray2 and/or the bypass, depending on which gear/bearing fails. We've fixed a few and pre-empted a few by removing the coating prior to failure. Seen no black coating on C558 shafts. They have also failed on units without the coating.

There's also a bulletin #10990 about a drive belt falling into the gap between gear 28T A79J220701 and the drive pack frame. It has been changed in production, affecting some 45/55/65 models.
