Multi Bypass Misfeed Troubleshooting Procedures
• Paper is not detected.
• Paper is not taken up at all.
• Paper is stopped at the Transport Rollers.
Step Check Result Action
1 I/O check for Manual Feed Paper Empty Sen-
sor operation: the voltage across PJ2A-3 on
Master Board and GND is DC0V when the sen-
sor is unblocked and DC5V when the sensor is
blocked.
YES Change Master Board.
NO Correct actuator.
Change sensor.
Step Check Result Action
1 Paper meets product specifications. NO Change paper.
2 Paper is curled, wavy, or damp. YES Change paper.
Instruct user in correct
paper storage.
3 Friction Pad and guide plate are dirty with
paper dust, deformed, or worn.
YES Clean or change.
4 Manual Bypass Take-Up Roll is dirty with paper
dust, deformed, or worn.
YES Clean or change.
5 Upper Vertical Transport/Manual Feed Motor
turns when the Start key is pressed with the
Multi Bypass Tray selected.
NO Correct drive coupling.
Change motor or Master
Board.
Step Check Result Action
1 Manual Feed Paper Pick-Up Solenoid opera-
tion when the Start key is pressed with paper
loaded in the Multi Bypass Tray: the voltage
across PJ2A-6 on Master Board and GND is
DC24V when the solenoid is deenergized and
DC0V when the solenoid is energized.
YES Change solenoid.
NO Change Master Board.
2 Transport Rollers are dirty with paper dust,
deformed, or worn.
YES Clean or change.
3 I/O check for Transport Roller Sensor opera-
tion: the voltage across PJ4A-13A on Master
Board and GND is DC0V when the sensor is
unblocked and DC5V when the sensor is
blocked.
YES Change Master Board.
NO Correct actuator.
Change sensor.
