developer motor wont always start i can get it to spin by manually turning it. is it a bad motor? or is it like some kyoceras that give motor error codes when interlock switches fail

Re: minolta di470 code 0090

We had a lot of these machines in the past and never ever a single C-0090 service code. Only thing I can imagine is an obstruction in the developing unit/drive. Did you check if the mag roller is turning freely? Occasionally we had the inner bearings go bad.

thank you hans,
developer unit turns freely, motor will turn every so often and makes a buzzing sound when it decides to turn

Garry, when those stepper motors make a buzzing/whining sound it is most of the time some kind of overload.
