Table 6-2 Control-panel messages (continued) Control panel message Description Recommended action 9 = ETB motor startup error A = ETB motor rotation error 3. Reconnect the connector J4613 between the ETB and the printer, and J1011 on the DC controller PCB. B = Developing disengaging motor startup error C = Developing disengaging motor rotation error Y Description 4. Replace the ETB. Fuser motor error 1. Reconnect the connectors J4605 for the fuser motor and J1024 on the DC controller PCB. 0 = Black or N/A 1 = Cyan 2 = Magenta 3 = Yellow 2. Run the component test to verify that the fuser motor is working correctly. 3. Replace the fuser motor. Print cartridge motor error 1. Run the component test to verify that the print cartridge motor is working correctly. 2. Reconnect the print cartridge connector on the DC controller PCB (J1018 for magenta and black, J1017 for cyan and yellow). On the motor itself, reconnect the connectors (J4603 for magenta, J4604 for black, J4601 for yellow, and J4602 for cyan). 3. Replace the drum drive assembly for the indicated print cartridge. Developing disengaging motor error 1. Run the component test to verify that the print developing disengaging motor is working correctly. 2. Reconnect the connectors J468 and J1020 between the developing disengaging motor and the DC controller PCB. 3. Replace the developing disengaging motor. 60.X ERROR To continue turn off then on A tray lifting error has occurred, where X is the number of the tray. This typically happens when a tray is overfilled or the media is not properly aligned. 60.2 = tray 2 60.3 = tray 3 60.4 = tray 4 1. Turn the MFP off and then on. 2. Verify that the tray is not overfilled and that media is aligned in the tray properly. 3. For tray 2, verify that connector J93 on the DC controller is firmly seated. This connector is for the lift motor. 4. Verify that connector J4618 is securely connected, and then check connector J1015 on the DC controller. ENWW Control-panel messages 533
