E732 0001 00 Title Scanner communication error
Description A communication error between the Reader Controller
PCB and the Main Controller PCB 2 was detected at
standby/scanning.
Remedy [Related parts]
- Harness between the Main Controller PCB 2 (J3003)
and the Reader Controller PCB (PCB1/J109) (Unit of
replacement: CABLE, INTERFACE)
- Harnesses from the Relay PCB to the Reader Controller
PCB
1. Relay PCB (UN5/J426) to Relay Connector (6P) (Unit
of replacement: CABLE, DC POWER SUPPLY)
2. Relay Connector (6P) to Reader Controller PCB (PCB1/
J101) (Unit of replacement: CABLE, READER POWER
SUPPLY)
- Main Controller PCB 2 (Unit of replacement: MAIN
CONTROLLER PCB ASS'Y, 2)
- Reader Controller PCB (PCB1) (Unit of replacement:
READER CONTROLLER PCB ASSEMBLY)
- Relay PCB (UN5) (Unit of replacement: RELAY PCB
ASSEMBLY)
[Remedy]
1. Place an original on the Copyboard and make a copy.
a. If the error is not reproduced, collect debug log (Sublog)
and contact to the sales company without replacing the
parts because of the possibility of sequence error.
b-1. If "Scanning..." is displayed or the error is
reproduced, check (connection and conduction state of)/
replace the related harness/cable, connector and parts.
b-2. Check that the copy image is output normally.
b-3. If the error is not cleared, collect debug log (Sublog)
and contact to the sales company.
[Reference]
- If the cause of the error cannot be identified by
analyzing Sublog, it may require investigation separately.
- Before replacing the Reader Controller PCB, back up
the service mode data (approx. 2 min) and restore the
backup data after the replacement so the data may be
able to be protected.
