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: 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: 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). Startup failure • A LOW Polygon Motor (M2) Lock signal is not detected within a given period of time that begins 1 sec. after the Polygon Motor has started turning.
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
Lock signal fault: Unstable after the first Lock signal has been detected • For a period of 1 sec. after the first LOW Polygon Motor (M2) Lock signal (first Lock) has been detected, the next LOW Polygon Motor Lock signal is not detected. Lock signal fault: Lock signal out-of-timing • A LOW Polygon Motor (M2) Lock signal is not detected for a continuous given period of time while the rotation of the Polygon Motor remains stabilized. Faulty Lock signal • A LOW Polygon Motor (M2) Lock signal is detected for a given period of time or more when the Polygon Motor remains deenergized.
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.
