• Code: E074-0000-05
• Description: Primary Transfer Roller disengagement control error
• Causes: Signal was not detected although the ITB Pressure Release Switch was turned ON/OFF for 6 times.
• Remedy: [Related parts] R1.00 - Harness between the DC Controller PCB (UN04/J162) and the ITB Pressure Release Switch (SW07/J6005) - Harness between the DC Controller PCB (UN04/J140) and the Primary Transfer Separation Solenoid (SL01/J5708) - Fuse in the DC Controller PCB (UN04/FU07) - ITB Guide Rail - Main Drive Unit - ITB Unit - DC Controller PCB (UN04) [Remedy] Perform the following in the order while checking whether the error is cleared. 1. Check that the ITB Unit is installed in the machine. 2. Replace the ITB Unit. 3. Check the harness between the DC Controller PCB and the ITB Pressure Release Switch. 4. Check the harness between the DC Controller PCB and the Primary Transfer Separation Solenoid. 5. Measure the both ends of the fuse in the DC Controller PCB using a tester. a. If the measurement value is less than 1 ohm (conduction state), 1. Replace the ITB Guide Rail (Front/Rear). 2. Replace the Main Drive Unit. 3. Replace the DC Controller PCB. b. If the measurement value is 1 ohm or higher (non conduction state), replace the DC Controller PCB. [Reference] Before replacing the DC 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> DSRAMBUP - Restoration: COPIER (LEVEL2)> FUNCTION> SYSTEM> DSRAMRES
