Color and K pressure - Color and K Color and K retraction OFF (blocked): OFF (blocked) retraction.K pressure - Color and K pressure Color and K pressure ON (not blocked):ON (not blocked).Color and K retraction - Color and K pressure.Color and K pressure - K K pressure ON (not blocked) :OFF (blocked) pressure.Operation Position Sensor status (K: Color) Even after a predetermined period of time has elapsed since the transfer belt starts pressure/retraction operation, the pressure welding alienation sensor/K or the pressure welding alienation sensor/color is not in the status corresponding to each of the transfer belt pressure/retraction operations.At the completion of transfer belt pressure/ retraction operations, the pressure welding alienation sensor/K or the pressure welding alienation sensor/color is not in the status corresponding to each of the transfer belt pressure/retraction operations.Description: Transfer belt pressure welding alienation.2 PS50 I/O check, sensor check PFTDB CN4-9 (ON) Q-5 3 M3 operation check PFTDB CN5-3 (REM) Q-6 4 Change M3 - 5 Change PRCB Remedy: 1 Check the M3 connector for proper connection and correct as necessary.Causes: Pressure welding alienation sensor (PS50) 2nd image transfer pressure retraction motor (M3) Printer control board (PRCB).The pressure welding alienation sensor doesn’t turn ON (pressuring) even after the lapse of a given period of time after the 2nd image transfer pressure retraction motor has started rotating during the 2nd image transfer roller is pressuring.The pressure welding alienation sensor doesn’t turn OFF (retracting) even after the lapse of a given period of time after the 2nd image transfer pressure retraction motor has started rotating during the 2nd image transfer roller is retracting.Description: Secondary transfer roller pressure welding alienation.3 PS43 I/O check, sensor check PRCB CN25-11 (ON) C-12 4 PS44 I/O check, sensor check PRCB CN25-14 (ON) C-12 5 M15 operation check PRCB CN8-1 to 2 C-12 6 Change drum unit /K - 7 Change M15 - 8 Change PRCB 2 Check the M15 connector for proper connection and correct as necessary. Remedy: 1 Check the drum unit/K for proper connection and correct as necessary.Causes: Drum unit /K Charging cleaner home sensor (PS43) Charging cleaner return sensor (PS44) Charge cleaning motor/K (M15) Printer control board (PRCB).During backward movement of the cleaner, the charging cleaner home sensor is not blocked after a predetermined period of time has elapsed.
#BIZHUB C452 TRANSFER BELT PC#
Description: PC charge cleaning malfunction.3 PS7 I/O check, sensor check FSCB PJ16-3 (ON) FS-527 J-5 4 M8 operation check FSCB PJ9-4 (REM) FS-527 J-2 5 Change M8 - 6 Change FSCB 2 Check the connector of M8 for proper drive coupling, and correct as necessary. Remedy: 1 Check the motor and sensor connectors for proper connection, and correct as necessary.Causes: Tray1 path switching motor (M8) Tray1 path switching home sensor (PS7) FS control board (FSCB).The tray1 path switching home sensor (PS7) is turned neither ON nor OFF even after the set period of time has elapsed after the tray1 path switching motor (M8) is turned ON.Description: Tray1 path switching motor drive malfunction.3 PS26 I/O check, sensor check FSCB PJ21-9 (ON) FS-527 J-2 4 M6 operation check FSCB PJ9-1 (REM) FS-527 J-2 5 Change M6 - 6 Change FSCB 2 Check the connector of M6 for proper drive coupling, and correct as necessary. Causes: Upper lower path switching motor (M6) Upper lower path switching sensor (PS26) FS control board (FSCB).The upper lower path switching sensor (PS26) is turned neither ON nor OFF even after the set period of time has elapsed after the upper lower path switching motor (M6) is turned ON.Description: Upper lower path switching motor drive malfunction.
