Code: C-1279
Classification: SD: SD-513/FD-504 abnormality
Cause:
After the creaser FD roller motor (M201) starts the home position search operation, the FD roller position sensor/1 (PS203) or the FD roller position sensor/2 (PS204) does not become active within a specified period of time. At the start, the activation of the PS203 and PS204 are detected at the same time.
Measures to take when alert occurs:
The main body and the option stop immediately.
Estimated abnormal parts:
- FD roller position sensor/1 (PS203)
- FD roller position sensor/2 (PS204)
- FD roller motor (M201)
- FD drive board (FDDB)
- SD control board (PCB1)
Press help key and activate and deactivate the sub power switch (SW2) of the main body.
Note:
- Faulty part isolation allows you to use the machine temporarily.
- When you press HELP key, the message "Please call service" and "Press [Help] to disengage" are alternately displayed.
- When you press HELP key, the message "Please turn on power again" is displayed.
Solution:
- Check the spine corner forming drive section, and if there is any abnormality, clean or repair it.
- Check the connector connection and the wiring harness between FDDB and the motor, PCB1 and the sensor. Then, repair them when there is any abnormality. (Wiring diagram: FD-504: 11-F) (Wiring diagram: FD-504: 3-G, 4-G).
- Check the connector connection and the wiring harness between FDDB and PCB1, and if there is any abnormality, repair it.
- Check the I/O drive of the motor and the coupling of the gear, and repair or replace it if there is any abnormality.
- Check I/O and the operation of the sensor, and if there is any abnormality, repair or replace it.
- Replace PS203 and PS204.
- Replace M201.
- Replace FDDB.
- Replace PCB1.
