This copier is going to be the death of me. The vertical conveying motor (for cassettes 3 and 4) either freezes up or runs backwards. I have replaced this motor 3 times and tried two cassette PWB's all with the same result. All but one motor I have installed has been destroyed. The last one I stopped after only a few seconds and was able to install into another machine. I have used one of the Cassette PWB's in another copier and it was fine. I have 26 volts to pins 2 and 5 before powering the motor. Afterward I lose all voltage to pin 5. If i remove the motor and reset the machine I get the voltage back to both pins. It seems whenever I install a motor it overloads the board and shuts down pins 4,5 and 6. I am about to pull another 6030 out of storage and replace both the board and the motor at the same time. I have tried this before but was not sure of the motor.
All other units attached to the PWB work correctly and the customer is still using the copier, just not tray 3 and 4. Any Ideas?
