Remedy: 1 Check the cable and connector for proper connection and correct as necessary. 2 Change PH Unit. 3 Change PWB-A.
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.
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 SL4 connector for proper connection and correct as necessary. 4 Check the PWB-A connector for proper connection and correct as necessary. 5 PC5 sensor check. PWB-A PJ14A-3 (ON) 2-G 6 SL4 operation check. PWB-A PJ11A-2 (REM) 2-G 7 M1 operation check. PWB-A PJ8A-5 (REM) PWB-A PJ8A-8 (LOCK) 2-G-H 8 Change PWB-A.
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 SL3 connector for proper connection and correct as necessary. 4 Check the PWB-A connector for proper connection and correct as necessary. 5 PC6 sensor check. PWB-A PJ9A-11 (ON) 2-F 6 SL3 operation check. PWB-A PJ10-5 (REM) 2-F 7 M1 operation check. PWB-A PJ8A-5 (REM) PWB-A PJ8A-8 (LOCK) 2-G-H 8 Change PWB-A.
Code: 16H
Description: Transfer Belt rotation failure
• The Belt Positioning Sensor does not detect the Transfer Belt position detection hole a second time even after the lapse of a predetermined period of time after it has detected one while the Transfer Belt is rotated.
Remedy: 1 Check the PWB-A connector for proper connection and correct as necessary. 2 PC4 sensor check. PWB-A PJ9A-8 (ON) 2-E. 3 Change Transfer Belt Unit. 4 Change PWB-A.
Code: 17H
Description: Rack rotation failure
• The Rack Positioning Sensor is in the blocked state when the Rack Motor remains deenergized. • The Rack Positioning Sensor is not blocked a second time even after the lapse of a predetermined period of time after it has been blocked once while the Rack Motor remains energized. • The Rack Positioning Sensor is unable to detect the• The count value of the edge of ON signal of the Rack Positioning Sensor during each developing positions are not a predetermined value while the Rack Motor is turning. deceleration control position after the lapse of a given period of time after the Rack Motor has started while the Rack Motor is turning.
Remedy: 1 Check the M2 connector for proper connection and correct as necessary. 2 Check M2 for proper drive coupling and correct as necessary. 3 Check the PWB-A connector for proper connection and correct as necessary. 4 PC3 sensor check. PWB-A PJ5A-11 (ON) 4-C 5 M2 operation check. PWB-A PJ5A-1-4 (Pulse Output) 4-B. 6 Change PWB-A.
Code: 18H
Description: Heating Roller warm-up failure
• The Thermistor does not detect a predetermined temperature value even after the lapse of a predetermined period of time after the current warm-up cycle has been started and the current warm-up cycle is thus not completed.
Remedy: 1 Check the Fusing Unit for correct installation (whether it is secured in position). 2 Check the Fusing Unit, PU, and PWB-A for proper connection and correct as necessary. 3 Check the lever of the Safety Switch and correct as necessary. 4 Change the Fusing Unit. 5 Change PWB-A. 6 Change PU.
