• Code: C0F33
• Description: ATDC adjustment failure
  • In an F8 (ATDC control voltage automatic adjustment) operation, the adjustment of ATDC control voltage is not completed within 1 min. after the ATDC Sensor sampling. • In an F8 operation, the control voltage falls outside the range of 5.39 V to 8.15 V.
• Remedy: 1 ATDC Sensor and Master Board are connected properly. NO Correct connection. 2 The voltage across PJ6PU1-5 on Power Supply Unit and GND is DC5 V. YES Change I/C. Change Master Board. NO Change Power Supply Unit.

• Code: C1038
• Description: Engine connection error
  • The system fails in checking initial engine connection when the Power Switch is turned ON. • The system succeeded in checking initial connection when the Power Switch was turned ON; then it fails in rechecking initial connection through the execution of a software reset when a communications error occurs during operation.
• Remedy: 1. Check the connection between Master Board and MFB2 Board. 2. Reset the malfunction and turn OFF and ON the Power Switch. 3. Change MFB2 Board. Change Master Board.

• Code: C1300
• Description: Polygon Motor malfunction
  <Faulty start detection> • The Lock signal is not detected at any time during a given period of time 1 sec. after the Polygon Motor has been energized. <Faulty Lock signal detection> • No Lock signals are detected at any time during the 1-sec. period which starts 1 sec. after the first Lock. <Out-of-timing Lock detection> • The Lock signal is not detected for a continuous 0.5sec. period while the Polygon Motor is in the stabilized turning state. <Abnormal Lock detection> • The Lock signal remains ON for a continuous 5-sec. period while the Polygon Motor remains deenergized.
• Remedy: 1. Reset the malfunction and turn OFF and ON the Power Switch. 2. Check the connection between PH Assy and Master Board. 3. Change PH Assy. Change Master Board.

• Code: C133A
• Description: Communications error (G/A)
  Communications with the gate array for expansion I/O (the IC mounted on the Master Board) fail
• Remedy: 1. Reset the malfunction and turn OFF and ON the Power Switch. 2. Check the connection between each of the following and Master Board. A. 2nd Drawer paper source unit B. 3rd Drawer paper source unit C. 4th Drawer paper source unit D. 5th Drawer paper source unit E. OT-102 F. JS-201 3. Disconnect the connection between the copier and A to F and then turn OFF and ON the Power Switch.- If the malfunction code display persists, change Master Board. - If the malfunction is no longer detected, connect the connectors sequentially and turn OFF and ON the Power Switch. When C133A is detected, check the connector of the corresponding paper source unit and, if it is intact, change the PWB-A of the unit.

• Code: C133B
• Description: Communications error (option I/F)
  The connection status of a finishing option is changed after the power has been turned ON.
• Remedy: 1. Reset the malfunction and turn OFF and ON the Power Switch. 2. Check the connection between Master Board (copier) and Control Board (Finisher). 3. Unplug the connector between Master Board and Control Board and turn OFF and ON the Power Switch. - If the malfunction code display persists, change Master Board. - If the malfunction is no longer detected, change Control Board.

• Code: C13C0
• Description: I/C initialization failure
  After failing to blow the imaging cartridge fuse two consecutive times, the I/C is determined to be new.
• Remedy: 1. Reinstall I/C, reset the malfunction, and turn OFF and ON the Power Switch. 2. Check the connection between I/C fuse and Master Board. 3. Change Master Board.

• Code: C13D0
• Description: Faulty EEPROM
  EEPROM, in which no initial data is written, is found.
• Remedy: 1. Reset the malfunction, turn OFF and ON the Power Switch, and unplug the power cord and plug it back in. 2. Check the connection between IC3 of Master Board and EEPROM. 3. Change Master Board. 4. Change EEPROM. For the precautions to be observed when changing the EEPROM, see DIS/ REASSEMBLY, ADJUSTMENT.

• Code: C13F0
• Description: HSYNC detection failure
  • The SOS falling edge is not detected for 0.2 sec. or more after the Polygon Motor has been energized and laser output started. • No SOS falling edges are detected while VIA remains ON.
• Remedy: 1. Reset the malfunction and turn OFF and ON the Power Switch. 2. Check the connection between PH Assy and Master Board. 3. Change PH Assy. Change Master Board.
