E009 0002 05 Title Pressure error (it is highly possible that grease is
scattered on the surface of the cam.)
Description Unable to detect stopping of the cam at the specified
position even if pressure is applied 10 times.
Remedy Clean the scattered grease and excess grease on the
gear at the rear side of the host machine. Procedure is as
follows.
1. Remove the Fixing Assembly.
2. Remove the Gear Cover at the rear side of the host
machine, and remove the Pressure Release Stopper and
the Pressure Release Support Plate (so that the gear is
easily cleaned).
3. Wipe off the scattered grease around the Pressure
Release Cam and the Pressure Plate with lint-free paper
moistened with alcohol.
4. Wipe off the excess grease on the side of the gear and
the shaft.
E012 0101 05 Title Y Drum Encoder 1 and 2 signal error
Description Y Drum Encoder 1 and 2 signal error (It was detected that
the motor was rotating, but not the encoders.)
Remedy 1. Check connection of drum encoder sensor 1 and 2
(UN31, UN32).
2. Check that the drum encoder sensor Wheel is properly
installed.
3. Check connection of the Drum Driver PCB (UN4).
4. Manually turn the Rotor of the Drum Motor
counterclockwise and check that the drum encoder
sensor Wheel rotates. -> If the wheel does not rotate,
replace the Drum Drive Unit.
5. Take out the drum encoder sensor to clean the Sensor
and the Wheel.
6. Replace the drum encoder sensor.
7. Replace the Drum Driver PCB (UN4).
E012 0102 05 Title Faulty signal with Y drum encoder sensor 1
Description The signal was not detected for 100 msec or more.
Remedy
1. Check connection of drum encoder sensor 1.
2. Take out drum encoder sensor 1 (UN31) to clean the
Sensor.
3. Replace drum encoder sensor 1.
4. Check if the harness of the drum encoder sensor is
faulty (replace the harness if it’s disconnected).
5. Replace the Drum Driver PCB (UN4).

E012 0103 05 Title Faulty signal with Y drum encoder sensor 2
Description The signal was not detected for 100 msec or more.
Remedy
1. Check connection of drum encoder sensor 2 (UN32).
2. Take out drum encoder sensor 2 to clean the Sensor.
3. Replace drum encoder sensor 2.
4. Check if the harness of the drum encoder sensor is
faulty (replace the harness if it’s disconnected).
5. Replace the Drum Driver PCB (UN4).
E012 0104 05 Title Failure in Y drum encoder sensor Wheel
Description Failure is detected with the Y drum encoder sensor Wheel
Remedy
1. Take out the drum encoder sensor to clean the Sensor
(UN31, UN32) and the Wheel.
2. Replace the drum encoder sensor Wheel.
3. Replace the drum encoder sensor.
4. Replace the Drum Driver PCB (UN4).
E012 0105 05 Title Failure in Y Drum Motor Control
Description Unstable rotation of the Y Drum Motor
Remedy
1. Check if the Drum is installed.
2. Take out the drum encoder sensor (UN31, UN32) to
clean the Sensor and the Wheel.
3. Remove the Process Unit and then install (reinstall) the
Process Unit.
4. Replace the Drum Unit.
5. Replace the Drum Driver PCB (UN4).
E012 0106 05 Title Failure in rotation of Y Drum Motor
Description The Y Drum Motor is not rotating at the specified speed/is
stopped.
Remedy 1. Check connection of the connector with the Y Drum
Motor (M1).
2. Check connection of the connector with Drum Driver
PCB (UN4).
3. Check the ITB (to see if the ITB is displaced/damaged.
Refer to E075 if the ITB is displaced).
4. Replace the ITB Cleaning Blade.
5. Replace the Drum Driver PCB (UN4).
