Code: C-0520
Description: 1st tandem PF-703 paper suction fan /1 (FM14) rotation abnormality. The FM14EM error detection signal is detected twice in succession within a specified period of time after FM14 was turned ON. However, an error detection signal (blowout of ICP) is not detected.
Causes: • Paper suction fan /2 (FM14: 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: 14-L) 3. Replace FM14. 4. Replace PFUDB.

Code: C-0521
