Re: sc440

Obviously you're stupid as you can't troubleshoot a main motor fault, and ridiculous comment such as "main motorrrrrrrrrrrrrrr" will get you nowhere fast.

I'd wish you good luck, however I'd be lying if I said that.

Re: sc440

Can't say in the 18 years that I have been fixing copiers, I've ever seen a main motor just go bad. I believe I would be measuring voltages at the motor and power supply. If I'm not mistaken, didn't the interlock switches go bad on this model causing laser failure faults and cause odd electrical gremlins. Just sayin, I wouldn't automatically suspect the main motor just yet.

Re: sc440

There is a cold solder on the main motor coil. There are 3 contact of coil that is soldered to the pcb. One of them is 100% sure that is not connected to the pcb.
