The machine shows c2704
Thread 2704
Abnormality in the black charging unit.
Possible causes:
Black charging unit
HV Unit
Print Control Board
Best guess is that you have a faulty charge unit. Try swapping the units around with another colour and see if the fault code shifts.

It's been a while since you posted that but you may just need to slide it back out and shake it back and forth (long ways) a few times. We had the same problem and the konica minolta tech told us to do that. It worked. DO NOT turn it upside down though.

I have a Konica bizhub c351 with and error code of c0211. I took the back off and played with the black motor that lifts the tray. The tray moves freely and the motor seems to move freely. When I turn the machine on it does not go through any kind of check like it did before it just goes to the same screen. Is there a way to reset this to get it going again to test if there is still a problem
