• Code: 732-0023-04
• Description: Communication error
• Causes: A communication error between the Reader Controller PCB and the Main Controller PCB 1 was detected at startup/recovery from sleep.
• Remedy: [Related parts] - Harness between the Reader Controller PCB (UN1/J109) and the Main Controller PCB 2 (PWB02/J4031) (Unit of replacement: CABLE, INTERFACE) - Harnesses from the Relay PCB to the Reader Controller PCB 1. Relay PCB (UN7/J505) to Relay Connector (6P) (Unit of replacement: CABLE, SIGNAL) 2. Relay Connector (6P) to Reader Controller PCB (PCB1/J101) (Unit of replacement: CABLE, READER POWER SUPPLY) - Main Controller PCB 2 (PWB02) (Unit of replacement: MAIN CONTROLLER PCB ASS'Y, 2) - Main Controller PCB 1 (PWB01) (Unit of replacement: MAIN CONTROLLER PCB ASSEMBLY, 1) - Reader Controller PCB (UN1) (Unit of replacement: READER CONTROLLER PCB ASSEMBLY) - Relay PCB (UN7) (Unit of replacement: RELAY PCB ASSEMBLY) [Points to note at work] After performing the remedy, check that the copy image is output normally. [Remedy] Check/replace the related harness/cable, connector and parts. [Reference] 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. - Backup: COPIER (LEVEL2)> FUNCTION> SYSTEM> RSRAMBUP - Restoration: COPIER (LEVEL2)> FUNCTION> SYSTEM> RSRAMRES

• Code: 732-0F01-04
• Description: Communication error
• Causes: Communication error that can be recovered by reboot If it is detected again immediately after reboot, E732-0001 is generated.
• Remedy: It is not necessary to perform a remedy because the machine is automatically rebooted after log collection.

• Code: 732-0F23-04
• Description: Communication error
• Causes: Communication error that can be recovered by reboot If it is detected again immediately after reboot, E732-0023 is generated.
• Remedy: It is not necessary to perform a remedy because the machine is automatically rebooted after log collection.

• Code: 732-8888-00
• Description: Error in the reader type
• Causes: When a scanner for the different model is detected during the communication with the reader.
• Remedy: Replace to the proper reader.

• Code: 732-9999-00
• Description: Reader detection error
• Causes: The Reader was detected with a printer model for the first time. Only the message "Turn OFF and then ON the power" is displayed on the screen instead of displaying an error code. The error log is recorded in "COPIER> DISPLAY> ERR".
• Remedy: Turn OFF and then ON the main power.

• Code: 733-0000-05
• Description: Communication error between the Main Controller PCB 1 and the DC Controller PCB
• Causes: Unable to make communication between the Main Controller PCB 1 and the DC Controller PCB. (Communication error was detected at startup.)
• Remedy: 1. Check the cable connection (connector connection error/open circuit). - DC Controller PCB: J441, J442, Main Controller PCB 2: J21, J22 - Main Controller PCB 2: J2, Main Controller PCB 1: J1019 2. Replace the DC Controller PCB/Main Controller PCB 2/Main Controller PCB1.

• Code: 733-0001-05
• Description: Communication error between the Main Controller PCB 1 and the DC Controller PCB
• Causes: Unable to make communication between the Main Controller PCB 1 and the DC Controller PCB. (Communication error was detected during power distribution (while the power is ON).)
• Remedy: 1. Turn OFF and then ON the power. 2. Check the cable connection (connector connection error/open circuit). - DC Controller PCB: J441, J442, Main Controller PCB 2: J21, J22 - Main Controller PCB 2: J2, Main Controller PCB 1: J1019 3. Replace the DC Controller PCB/Main Controller PCB 2/Main Controller PCB1.

• Code: 733-0002-05
• Description: Communication error between the Main Controller PCB 1 and the DC Controller PCB
• Causes: Error was detected in the signal from the DC Controller PCB to the Main Controller PCB 1. (Communication between the DC Controller PCB and the Main Controller PCB 1 is normal.)
• Remedy: 1. Check the cable connection (connector connection error/open circuit). - DC Controller PCB: J441, J442, Main Controller PCB 2: J21, J22 - Main Controller PCB 2: J2, Main Controller PCB 1: J1019 2. Replace the DC Controller PCB/Main Controller PCB 2/Main Controller PCB1.
