Code: 8A
Description: Paper jam in Tray 1 (T1)
Causes: 1 Harness connection failure of registration front sensor PCB ASSY. 2 Paper feeding kit worn out (MP/ T1/ LT). 3 Registration front sensor PCB failure (MP/ T1/ LT)
Remedy: 1 Harness connection failure of registration front sensor PCB ASSY Check the harness connection of the registration front sensor PCB ASSY in the appropriate tray, and reconnect it. 2 Paper feeding kit worn out (MP/ T1/ LT) Replace the paper feeding kit of the appropriate tray. (MP/ T1) Check the sensor performance following the procedure described in “Maintenance mode 32”. If any problem occurs, replace the front door unit ASSY. 3 Registration front sensor PCB failure (MP/ T1/ LT) (LT) Check the sensor performance following the procedure described in “Maintenance mode 32”. If any problem occurs, replace the LT paper feed frame unit. 4 Engine PCB failure Replace the engine PCB ASSY.

Code: 8B
