Description
Since multiple drum cartridges caused the message "Insert drum cartridge." although all the drum cartridges were mounted, the drum ITB motor (M1) was
replaced with a new one for solution.
Cause
Since the drum/ITB motor (M1) was faulty, it failed to drive drum cartridges, causing the symptom.
Field Remedy
1. In service mode > COPIER > Function > PART-CHK > MTR, enter '1' using the numeric key.
2. Press [OK] and [MTR-ON] in this order, and then check to make sure that the drum ITB motor (M1) operates. (Listen to the operating noise of the motor.)
Note: Be careful. The motor may not rotate even when the indication [OK] is displayed on the LCD.
3. If the drum ITB motor (M1) does not rotate, re-fit J11051 and J1107 connector of the drum ITB motor and J210 and J209 connectors on the DC controller
PCB.
4. If the symptom still occurs, replace the drum ITB motor with a new one.

Description
Since the message "Insert drum cartridge." was displayed upon power-on, the image formation high-voltage PCB (HV1) was replaced with a new one for
solution. In this inspection case, the message was displayed with regard to cyan.
Cause
Since the image formation high-voltage PCB (HV1) was faulty, high voltage was not supplied to the drum cartridge. This made this machine fail to recognize
the drum cartridge, causing the message.
Field Remedy
1. Re-fit the drum cartridge that the message is specifying.
2. If the symptom still occurs, re-fit J301 and J302 connectors of the image formation high-voltage PCB (HV1) and J112A and J112B connectors of the DC
controller PCB.
3. If the symptom still occurs, replace the image formation high-voltage PCB (HV1) with a new one.

Description
Since the message "Replace the drum cartridge." appeared (for all the 4 colors) although no drum cartridge reached the end of service life, the image formation
high-voltage PCB was replaced for solution. When the same symptom occurs, perform the following steps in sequence.
Cause
Since the image formation high-voltage (HV1) PCB was faulty, bias was not applied to the developing cylinder in each drum cartridge, causing the cylinders
to fail to attract toner particles. This machine recognized this situation as a fault in each drum cartridge, and displayed the message.
Field Remedy
1. Pull out the drum cartridges and then re-insert them.
2. Re-fit all the connectors of the image formation high-voltage (HV1) PCB.
3. Re-fit J112A and J112B connectors of the DC controller PCB.
4. Replace the image formation high-voltage (HV1) PCB with a new one.
