• Code: E025-04C0
• Description: Error in Bk Toner Insertion Inlet Cover Sensor (PS7). Unable to detect opening of the Toner Insertion Inlet Cover when removing the Toner Container
• Remedy: Identify the cause of the error whether it is due to link mechanism to open the Toner Insertion Inlet Cover or problem at the Toner Insertion Inlet Cover Sensor side. 1. Perform the user mode (Adjustment/Maintenance> Replace Specified Toner) to check if the Toner Insertion Inlet Cover opens normally (damage, slide of shaft area, etc.). 2. Check if the Toner Insertion Inlet Cover Sensor is soiled and the installation of the sensor. 3. Check the service mode (COPIER> I/O> DC-CON> P051 bit3) to see that the output value of the Toner Insertion Inlet Cover Sensor is changed normally when opening/closing the Toner Insertion Inlet Cover. If it is normal, the value becomes 0 by driving the Hopper Unit with the Toner Container Removing Tool and opening the Toner Insertion Inlet Cover. When closing the Toner Insertion Inlet Cover by hand, it becomes 1. 3-1. When the Toner Insertion Inlet Cover is not opened although the Hopper Unit is driven, check the drive system from upstream (Hopper Unit -> link mechanism of Hopper Tray -> Toner Insertion Inlet Cover Unit). If it is damaged, replace the damaged part and then perform step 5 and later steps. 3-2. When the output value is not changed normally although the Toner Insertion Inlet Cover can be opened/closed, check the Sensor Harness (to see if the harness is caught, disconnected or physically removed, *including the Relay Connector). If there is no problem, replace the sensor. After checking the output value in step 3, perform step 5 and later steps. 4. If the problem is not solved by replacing the foregoing parts, replace the DC controller PCB and then perform step 5 and later steps. 5. Clear the error in service mode (COPIER> FUNCTION> CLEAR> ERR), and then turn OFF and then ON the main power. 6. Replace the toner (reinstall the removed Toner Container) at least once in user mode (Adjustment/ Maintenance> Replace Specified Toner), and check that toner replacement can be performed normally.

• Code: E056-0001
• Description: Reverse Roller disengagement home position error. At initial operation, the Reverse Roller Disengagement HP Sensor (PS101) failed to detect home position despite an operation of the Reverse Disengagement Motor (M54).
• Remedy: 1. Replace the Reverse Disengagement Motor. 2. Check the mechanism to detect home position for disengagement of the Reverse Roller. 3. Replace the Reverse Roller Disengagement HP Sensor.

• Code: E056-0002
• Description: Reverse Roller operation error. During printing, the Reverse Roller Disengagement HP Sensor (PS101) failed to detect change in the detection flag despite an operation of the Reverse Disengagement Motor (M54).
• Remedy: 1. Replace the Reverse Disengagement Motor. 2. Check the mechanism to detect home position for disengagement of the Reverse Roller. 3. Replace the Reverse Roller Disengagement HP Sensor

• Code: E060-0001
• Description: Primary Charging Wire Shutter HP open error. The Primary Charging Wire Shutter HP Sensor (PS92) detected that the shutter was open although it was moved to the close position.
• Remedy: 1. Check connection of the Primary Charging Wire Cleaning Motor (M1). 2. Replace the Primary Charging Wire Cleaning Motor (M1). 3. Check connection of the Primary Charging Wire Shutter HP Sensor (PS92). 4. Replace the Primary Charging Wire Shutter HP Sensor (PS92). 5. Check shutter mechanism of the Primary Charging Assembly. 6. Replace the Primary Charging Assembly. 7. Replace the DC Controller PCB.

• Code: E060-0002
• Description: Primary Charging Wire Shutter HP close error. The Primary Charging Wire Shutter HP Sensor (PS92) detected that the shutter was closed although it was moved to the open position.
• Remedy: 1. Check connection of the Primary Charging Wire Cleaning Motor (M1). 2. Replace the Primary Charging Wire Cleaning Motor (M1). 3. Check connection of the Primary Charging Wire Shutter HP Sensor (PS92). 4. Replace the Primary Charging Wire Shutter HP Sensor (PS92). 5. Check shutter mechanism of the Primary Charging Assembly. 6. Replace the Primary Charging Assembly. 7. Replace the DC Controller PCB

• Code: E060-0011
• Description: Primary Charging Wire Shutter error 1 when cleaning the Primary Charging Wire. The Primary Charging Wire Shutter HP Sensor (PS92) failed to be detected although 10 seconds have passed since the Primary Charging Wire Shutter started its operation.
• Remedy: 1. Check connection of the Primary Charging Wire Shutter HP Sensor (PS92). 2. Replace the Primary Charging Wire Shutter HP Sensor (PS92). 3. Check shutter mechanism of the Primary Charging Assembly. 4. Replace the Primary Charging Assembly. 5. Replace the DC Controller PCB.

• Code: E060-0012
• Description: Primary Charging Wire Shutter error 2 when cleaning the Primary Charging Wire. The Primary Charging Wire Shutter HP Sensor (PS92) remained to be detected although 10 seconds have passed since the Primary Charging Wire Shutter started its operation.
• Remedy: 1. Check connection of the Primary Charging Wire Shutter HP Sensor (PS92). 2. Replace the Primary Charging Wire Shutter HP Sensor (PS92). 3. Check shutter mechanism of the Primary Charging Assembly. 4. Replace the Primary Charging Assembly. 5. Replace the DC Controller PCB.

• Code: E060-0023
• Description: Error in the Primary Charging Wire Shutter position during rotation of the Bk Drum. Faulty position of the Primary Charging Wire Shutter was detected while the Bk Drum was rotating.
• Remedy: 1. Check connection of the Primary Charging Wire Cleaning Motor (M1). 2. Replace the Primary Charging Wire Cleaning Motor (M1). 3. Check connection of the Primary Charging Wire Shutter HP Sensor (PS92). 4. Replace the Primary Charging Wire Shutter HP Sensor (PS92). 5. Check shutter mechanism of the Primary Charging Assembly. 6. Replace the Primary Charging Assembly. 7. Replace the DC Controller PCB.
