Description: At start-up, home position is not detected when the horizontal registration assembly is moved 100 mm in the direction of home position
Causes: The horizontal home position sensor is faulty. The horizontal registration motor is faulty. The DC controller PCB is faulty.
Remedy: 1. Connector Are the connectors of the horizontal registration home position sensor and the horizontal registration motor connected? a. DC controller PCB (J304) <-> relay connector <-> horizontal registration home position sensor b. DC controller PCB (J304) <-> relay connector <-> horizontal registration motor NO: Connect the connectors. 2. Sensor lever (damage and interference), Sensor Is abnormal noise heard from the horizontal registration assembly in keeping with the motor rotation? YES: a. The horizontal registration assembly is out of place because of damage to the sensor lever. Replace the sensor lever. b. The horizontal registration assembly malfunctions because of the presence of foreign matter. Remove the foreign matter. c. The sensor is faulty and cannot detect home position. Replace the sensor. 3. Horizontal registration motor, DC controller PCB Is the horizontal registration motor control signal generated by the DC controller PCB? J304-1/2: 24 V, J304-3/4/5/6: motor excitation signal YES: The horizontal registration motor is faulty. Replace the motor. NO: Replace the DC controller PCB.
Code: E064-0000
Description: The presence of a high-voltage error is communicated by the composite power supply PCB (The output for primary charging, developing, or transfer has deviated from a specific level of voltage)
Causes: The contact has poor connection. The wiring is faulty. The composite power supply PCB is faulty. The DC controller PCB is faulty. proce
Remedy: 1. Contact Is any of the contacts of the primary charging roller, developing assembly, or transfer charging roller soiled? Or, is there poor contact? YES: Clean the contact, and set it once again. 2. Wiring Is the wiring between the contacts for the following normal: DC controller PCB (J301), composite power supply PCB (J136), primary charging roller, developing assembly, transfer charging roller? a. DC controller PCB (J301) <-> composite power supply PCB (J136) b. composite power supply PCB (J130-7) <-> primary charging roller contact c. composite power supply PCB (J130-1) <-> developing assembly contact d. composite power supply PCB (FT133) <-> transfer roller contact NO: Correct the connection. 3. Composite power supply PCB, DC controller PCB Try replacing the composite power supply PCB. Is the problem corrected? YES: Yes. NO: Replace the DC controller PCB.
Code: E100-0001
