• Code: E302-0002
• Description: During stream reading, the edge white addition processing does not end on the rear controller PCB after 10 sec
• Causes: The CCD PCB is faulty. The wiring is faulty (short circuit, open circuit). The reader controller PCB is faulty
• Remedy: 1. Connector Are the connectors (J6001/J6002) on the CCD PCB and the connectors (J5002/J5003) on the reader controller PCB connected securely? NO: Connect the connectors securely. 2. CCD unit Try replacing the CCD unit. Is the problem corrected? YES: End. 3. Reader controller PCB, Main controller PCB Try replacing the reader controller PCB. Is the problem corrected? YES: End. NO: Check the wiring; if normal, replace the main controller PCB.

• Code: E315
• Description: Any of the following is true in the image processing by the main controller:
  The image data has a fault The encoding/decoding operation for image data has a fault The image processing element of the main controller PCB has a fault
• Causes: The image data is faulty. The main controller PCB is faulty. The HDD is faulty.
• Remedy: If this error occurs during normal copying or printing, the job in question (image data) is cleared when the main power switch is turned off and then on again; i.e., the machine will be reset. If this error occurs frequently, however, a fault on the main controller PCB is a possibility. Further, if this error occurs in a specific image within the MAIL BOX, damage in data may be assumed; be sure to delete the image from the MAIL BOX.

• Code: E420-0001
• Description: When the power switch of the host machine is turned on, the back-up data from the EEPROM cannot be read or the data that has been read has a fault
• Causes: The EEPROM is faulty. The ADF controller PCB is faulty.
• Remedy:

• Code: E421-0001
• Description: The back-up data cannot be written to the EEPROM, or the data that has been written has a fault
• Causes: The EEPROM has a fault. The ADF controller PCB has a fault.
• Remedy:

• Code: E422-0001
• Description: While the ADF is in standby, the communication with its host machine is disrupted for 5 sec or more; or, while the ADF is in operation, the communication with its host machine is disrupted for 0.5 sec or more
• Causes: The IPC communication is faulty. The communication line has an open circuit. The ADF controller PCB is faulty.
• Remedy:

• Code: E500-0000
• Description: The communication between the copier and the finisher is disrupted and is not corrected for 5 sec or less
• Causes: The copier harness is faulty. (disconnected connector, open circuit) The finisher controller PCB or the copier’s DC controller PCB is faulty.
• Remedy:

• Code: E501-0001
• Description: The communication between the finisher controller PCB and the puncher drive PCB is disrupted
• Causes: The finisher controller PCB is faulty. The puncher drive PCB is faulty.
• Remedy:

• Code: E505-0001
• Description: When the main power is turned on, the checksum of the finisher controller PCB has a fault
• Causes: The EEPROM is faulty. The finisher controller PCB is faulty. The puncher driver PCB is faulty.
• Remedy:
