• Code: C0F32
• Description: Faulty ATDC Sensor
  - The measurement taken by the ATDC Sensor (UN1) at a time 2.0 sec. after the Main Motor (M1) has started turning is less than 5% (greater than 4.63 V).
  - The measurement taken by the ATDC Sensor (UN1) at a time 2.0 sec. after the Main Motor (M1) has started turning is 19% or more (1.41 V or less).
• Remedy: 1 Check to see if developer is available. 2 Check the ATDC Sensor connectors for proper connection and correct as necessary. 3 Change UN1. 4 Run ?gATDC Auto Adjust. 5 Change PWB-A. 6 Change PU1.

• Code: C0F33
• Description: Improperly adjusted ATDC Sensor
  - The adjustment of the ATDC control voltage is not completed within 1 sec. after sampling has started of the ATDC Sensor (UN1) as part of an operation of ATDC Sensor Automatic Adjustment.
  - The ATDC Sensor control voltage falls outside the range of 5.39 V to 8.15 V during an operation of ATDC Sensor Automatic Adjustment.
• Remedy:

• Code: C1038
• Description: Engine connection failure
  Master Board (PWB-A) to Control Board (PWB-C/C) connection failure
  - There is no acknowledge signal transmitted from the Master Board (PWB-A) to Control Board (PWB-C/C) for 1.5 sec. or more.
  - An error command signal is transmitted from the Control Board (PWB-C/C) to Master Board (PWB-A).
  - An error status signal is transmitted from the Master Board (PWB-A) to Control Board (PWB-C/C).
• Remedy: 1 Turn OFF and ON the Power Switch. 2 Check the PWB-A connectors for proper connection and correct as necessary. 3 Check the PWB-C/C connectors for proper connection and correct as necessary. 4 Check for proper connection between PWB-A and PWB-C/C and correct as necessary. 5 Change PWB-A. 6 Change PWB-C/C.

• Code: C1200
• Description: Faulty ASIC/memory
  ASIC/memory (for image and control) fault
  A write or read error occurs with SRAM on the Control Board (PWB-C/C).
• Remedy: 1 Turn OFF and ON the Power Switch. 2 Check memory on PWB-C/C for connection and correct as necessary. 3 Change PWB-C/C.

• Code: C1300
• Description: Polygon Motor malfunction
  -Startup failure
  - Lock signal fault: Unstable after the first Lock signal has been detected
  - Lock signal fault: Lock signal out-of-timing
• Remedy: 1 Turn OFF and ON the Power Switch. 2 Check for proper connection between the PH Unit and Master Board and correct as necessary. 3 Change the PH Unit. 4 Change PWB-A.

• Code: C133B
• Description: Communication with option error
  - It is not possible to communicate with the Printer Board within a predetermined period of time during a print cycle.
• Remedy:

• Code: C133D
• Description: ROM check error
  - An error is detected of the flash ROM chip on the Fax Board when the Power Switch is turned ON.
• Remedy:

• Code: C13F0
• Description: Faulty HSYNC
  Laser scanning system malfunction
  - The SOS Sensor does not detect a rising edge of SOS within a given period of time after the Polygon Motor (M2) has started turning and a laser output has been started.
  - The SOS Sensor detects no rising edges of SOS while VIA (image area control) is ON.
• Remedy: 1 Turn OFF and ON the Power Switch. 2 Check for proper connection between the PH Unit and Master Board and correct as necessary. 3 Change the PH Unit. 4 Change PWB-A.
