Code: C-0504
Description: 1st tandem PF-703 paper leading edge separation fan /Fr2 (FM7) rotation abnormality. The FM7EM error detection signal is detected twice in succession within a specified period of time after FM7 was turned ON. However, an error detection signal (blowout of ICP) is not detected.
Causes: • Paper leading edge separation fan /Fr2 (FM7: PF-703) • PF drive board (PFUDB: PF-703)
Remedy: 1. Check the connector connection and the wiring between PFUDB and the fan, and repair it if any abnormality. 2. Rotate the fan or I/O by hand, and repair it if any abnormality. (Wiring diagram: PF-703: 11-F) 3. Replace FM7. 4. Replace PFUDB.

Code: C-0505
