Description: Scanner motor malfunction
• A low motor lock signal is not detected even after the lapse of a predetermined period of time after the scanner motor has been started.
• The motor lock signal remains HIGH for a predetermined consecutive period of time while the scanner motor remains energized.
Remedy: 1 Check to see if the lock lever of the Scanner unit is unlocked and unlock the lock lever if it is locked. 2 Check the M5 connector for proper connection and correct as necessary. 3 Check M5 for proper drive coupling and correct as necessary. 4 Check the PRCB connector for proper connection and correct as necessary. 5 M5 operation check. 6 Change PRCB. 7 Change DCPU2. 8 Change DCPU1.
Code: 102H
Description: Faulty ir exposure lamp
• The intensity of the light emitted from the exposure lamp of the scanner falls short of the specified value.
Remedy: 1 Check the exposure lamp for lighting condition when the power switch is turned ON and, if any faulty symptom is evident, correct the Scanner Unit. 2 Check the PRCB connector for proper connection and correct as necessary. 3 Change scanner unit. 4 Change PRCB.nge DCPU1.
Code: 10H
Description: Polygon motor malfunction
• A low motor lock signal is not detected even after the lapse of a predetermined period of time after the polygon motor has been started.
• The motor lock signal remains HIGH for a predetermined consecutive period of time while the polygon motor remains energized.
Remedy: 1 Check the cable and connector for proper connection and correct as necessary. 2 Change PH unit. 3 Change PRCB.
Code: 12H
Description: Laser malfunction
• The SOS signal is not detected within a predetermined period of time after the output of a laser has been started.
• The SOS signal is never detected in the image area.
Remedy: 1 Check the cable and connector for proper connection and correct as necessary. 2 Change PH unit. 3 Change PRCB.
Code: 14H
Description: 2nd image transfer pressure /retraction failure
• The state of the retraction position sensor/2nd image transfer is not changed from the unblocked to blocked state even after the lapse of a predetermined period of time during predrive.
• The retraction position sensor/2nd image transfer is in the unblocked state even after the lapse of a predetermined period of time during predrive.
• The retraction position sensor/2nd image transfer is not blocked (roller in the retracted position) within a predetermined period of time after the retraction sequence of the 2nd transfer roller has been started.
• The retraction position sensor/2nd image transfer is not unblocked (roller in the pressed position) within a predetermined period of time after the pressure sequence of the 2nd transfer roller has been started.
• The state of the retraction position sensor/cleaning blade is not changed from the blocked to unblocked state even after the lapse of a predetermined period of time during predrive.
Remedy: 1 Check the M1 connector for proper connection and correct as necessary. 2 Check M1 for proper drive coupling and correct as necessary. 3 Check the SD4 connector for proper connection and correct as necessary. 4 Check the PRCB connector for proper connection and correct as necessary. 5 PS5 sensor check. 8 Change PRCB.
Code: 15H
Description: Cleaning blade pressure /retraction failure
• The state of the retraction position sensor/cleaning blade is not changed from the blocked to unblocked state even after the lapse of a predetermined period of time during predrive.
• The retraction position sensor/cleaning blade is in the blocked state even after the lapse of a predetermined period of time during predrive.
• The retraction position sensor/cleaning blade is not unblocked (blade in the retracted position) within a predetermined period of time after the retraction sequence of the cleaning blade has been started.
• The retraction position sensor/cleaning blade is not blocked (blade in the pressed position) within a predetermined period of time after the pressure sequence of the cleaning blade has been started.
Remedy: 1 Check the M1 connector for proper connection and correct as necessary. 2 Check M1 for proper drive coupling and correct as necessary. 3 Check the SD3 connector for proper connection and correct as necessary. 4 Check the PRCB connector for proper connection and correct as necessary. 5 PS6 sensor check. PRCB PJ9PRCB-11 (ON) C-5 6 SD3 operation check. 8 Change PRCB.
