Error in the Toner Excess
Supply Sensor connection
detection
The connection detection
port was OFF at power-on.
1. Check the connection of the Toner Excess
Supply Sensor (TS2). Sensor side: J2038, J3124
(relay), J3090 (relay) PCB side: J3091 (relay),
J115 (Main Driver PCB (PCB2)) 2. Replace the
Toner Excess Supply Sensor (TS2). 3. Replace
the Main Driver PCB (PCB2). 4. Replace the DC
Controller PCB (PCB1).

The connection detection
port was OFF at power-on.
1. Check the connection of the Magnet Roller
Clutch (CL5). Sensor side: J2036, J3124 (relay),
J3090 (relay) PCB side: J3091(relay), J115 (Main
Driver PCB (PCB2)) 2. Replace the Magnet Roller
Clutch (CL5). 3. Replace the Main Driver PCB
(PCB2). 4. Replace the DC Controller PCB
(PCB1).

Developing Motor error
Lock error of the Developing
Motor (M2).
1. Check the connection of the Connector. Motor
side: J2319, Main Driver PCB (PCB2) side: J109
2. Check the voltage of the Developing Motor
(M2) J2152. If voltage is 0V, check the connection
of the Relay PCB J520. 3. Check the load of the
Developing Motor (M2). Manually turn the
Developing Motor (M2) located at the rear of the
host machine to check it. 4. Replace the
Developing Motor (M2). 5. Replace the
Developing Clutch (CL1). (When an error occurs
while the Developing Clutch is ON.) 6. Replace
the Main Driver PCB (PCB2). 7. Replace the DC
Controller PCB (PCB1).
