Description: 2nd image transfer pressure /retraction failure
• The state of the 2nd image transfer retraction position sensor is not changed from the unblocked to blocked state even after the lapse of a predetermined period of time during predrive. • The 2nd image transfer retraction position sensor is in the unblocked state even after the lapse of a predetermined period of time during predrive. • The 2nd image transfer retraction position sensor 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 2nd image transfer retraction position sensor 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 SD4 connector for proper connection and correct as necessary. 4 Check the PRCB connector for proper connection and correct as necessary. 5 PS3 sensor check. PRCB PJ12-3 (ON) 1600W: C-2 to 3 1650EN: C-2. 6 SD4 operation check. PRCB PJ10-6 (REM) 1600W: C-9 1650EN: C-9. 7 M1 operation check. PRCB PJ8-1 to 6 C-2. 8 Change PRCB.
