3-3-1 PAPER FEED MOTOR Adjustment

Perform the following adjustments when the paper feed motor unit is replaced:

1) When attaching the motor, fasten the screws so that the belt is properly stretched (in the

direction indicated by the blue arrow in the figure below).

2) After replacement, be sure to perform the service test print, and confirm that no strange noise or

faulty print operation (due to dislocation of the belt or gear, or out-of-phase motor, etc.) occurs.
