Block supply timeout (Y) error
The toner supply screw rotation sensor cannot detect
rotation of the screw.
1. Check the connection between the hopper/stirring
supply motor (M6) and the hopper driver PCB.
Motor side: J7100, J8106 PCB side: J1340
2. Check the connection between the toner feed screw
rotation sensor (PS9) and the hopper driver PCB.
Sensor side: J7418, J8106 PCB side: J1340
3. Replace the hopper/stirring supply motor.
4. Clean and replace the toner feed screw rotation
sensor.
5. Replace the toner supply pipe unit.
6. Replace the hopper unit.
CAUTION:
Remedies 5 and 6 are taken when the motor is
overloaded due to toner adhesion in the unit or gear
interlocking failure, etc. Since it is difficult to identify the
cause, it is recommended to replace the unit.
Toner container sealing/release holder shift cam HP
sensor timeout (Y) error
HP sensor of release holder shift cam cannot detect
within specified period of time.
1. Check the connection of the toner container drive
motor (M10) harness. (Check whether the wire is
not caught by parts.) Check the connection with the
hopper driver PCB.
Motor side: J7104 PCB side: J1370
2. Check the connection between the release holder shift
cam HP sensor (PS8) and the hopper driver PCB.
Sensor side: J7123, J8106 PCB side: J1340
3. Replace the toner container drive motor.
4. Clean and replace the release holder shift cam HP
sensor.
5. Replace the hopper unit.
CAUTION:
As for Remedy 5, since it is difficult to identify the cause,
