System Board

Turn the printer off and disconnect CN6 from the

 

 

system board. Turn the printer on and check for a

 

 

pulse of 24 V dc between CN6-1 and ground and

 

 

CN6-2 and ground on the system board, as the

 

 

machine goes through P-O-S-T. If the voltage is

 

 

not present, check for motor pins shorted to the

 

 

motor housing. If you find a shorted pin, replace

 

 

the motor. If you still have a failure after replacing

 

 

the motor, replace the system board.
