54.2 CAROUSEL ERROR CYCLE POWER
Description:
Indicates that the color toner carousel is not working correctly. This could be caused by an obstruction in the carousel path, such as a loose shutter or disengaged toner cartridge.
Remedy:
1 Turn the printer off and on to reset the printer. 2 Open the carousel door and waste toner tray. Look for an obstruction, such as a toner cartridge shutter catching on the waste toner tray. Verify the toner lock lever is fully locked. If the message does not clear after closing the doors, turn the printer off and on to reset the printer. 3 Clean the carousel position sensor (PS3) with compressed air. If the problem persists, replace the sensor. 4 Reconnect connector J701 on carousel motor PCA; connectors J641, J642, J644, and J648 on the main relay PCA; connector J672 on the subrelay PCA; and connector J102 on the power supply. 5 Check operation of the carousel stopper arm. Replace the carousel stopper solenoid. 6 Check electrical continuity between connector J641-1 (+24 VB) and J642-3 (PMP) on the main relay PCA when the door switch (SW641) is turned on. If there is no electrical continuity, replace the main relay PCA. 7 Check electrical continuity between connector J644-1 (PBK) and J644-2 (PMP) on the main relay PCA when the door switch (SW644) is turned on. If there is no electrical continuity, replace the black toner cartridge on/off switch. 8 Check electrical continuity between connector J642-1 (PYMC) and J642-2 (PBK) on the subrelay PCA when the door switch (SW673) is turned on. If there is no electrical continuity, replace the toner cartridge cover switch in the subrelay PCA. 9 Check electrical continuity between connector J642-1 (PYMC) and J648-1 (+24 VAR) on the main relay PCA when the door switch (SW642) is turned on. If there is no electrical continuity, replace the main relay PCA. 10 Measure the voltage across connector J648-1 (+24 VAR) and J648-3 (GND) on the main relay PCA after the printer is turned on. If the voltage is not 24 V, replace the main relay PCA. 11 Reconnect connectors J704 and J706 on the carousel motor PCA, and connector J220 on the controller board. 12 Reconnect connector J43 on the carousel position sensor, relay connector J42 and connector J207 on the controller board. 13 Measure the voltage across connector J220- A6 (RLSROT) and J220-B5 (GND) on the controller board after the printer is turned on. If the voltage changes to about 3.5 V from 0 V, replace the carousel motor PCA. 14 Replace the carousel motor (M1). 15 Replace the controller board.
