E021 0120 05 Title Developing screw rotation detection
Detection The difference between the maximum and the minimum of
detected inductance sampling values is equal to or lower than
0.5V.
Remedy Possible cause: The screw is not rotating due to failure in the
coupling between the main body and the Developing Assembly,
or the value of ATR Sensor (M) (UN40) failed to be read due to an
electrical trouble.
1. Remove the Drum Unit (M) and check no damage. (Replace
the Drum Unit (M) if defective)
2. Lift the pressure lever after the Drum Unit (M) is pushed all the
way in.
3. Check failure of the harness between the Drum Unit (M) and
the DC Controller PCB (UN09/J25) (trapped cable, open circuit,
connector disconnection)
4.Check the Drum Unit Relay PCB (M) (UN27) (Soil/ deformation/
damage)
5. Check the Drum Unit Memory PCB (M) (UN31) (Soil/ damage)
6.Replace the Drum Unit (M)
7. Replace the DC Controller PCB (UN09).
8. Replace the Main Drive Unit
E021 0220 05 Title Developing screw rotation detection
Detection The difference between the maximum and the minimum of
detected inductance sampling values is equal to or lower than
0.5V.
Remedy Possible cause: The screw is not rotating due to failure in the
coupling between the main body and the Developing Assembly,
or the value of ATR Sensor (C)(UN41) failed to be read due to an
electrical trouble.
1. Remove the Drum Unit (C) and check no damage. (Replace
the Drum Unit (C) if defective)
2. Lift the pressure lever after the Drum Unit (C) is pushed all the
way in.
3.Check failure of the harness between the Drum Unit (C) and
the DC Controller PCB (UN09/J25) (trapped cable, open circuit,
connector disconnection)
4.Check the Drum Unit Relay PCB (C) (UN28) (Soil/ deformation/
damage)
5.Check the Drum Unit Memory PCB (C) (UN32) (Soil/ damage)
6.Replace the Drum Unit (C).
7. Replace the DC Controller PCB (UN09).
8. Replace the Main Drive Unit

E021 0320 05 Title Developing screw rotation detection
Detection The difference between the maximum and the minimum of
detected inductance sampling values is equal to or lower than
0.5V.
Remedy Possible cause: The screw is not rotating due to failure in the
coupling between the main body and the Developing Assembly,
or the value of ATR Sensor (Bk) (UN42) failed to be read due to
an electrical trouble
1. Remove the Drum Unit (Bk) and check no damage. (Replace
the Drum Unit (Bk) if defective)
2. Lift the pressure lever after the Drum Unit (Bk) is pushed all the
way in.
3. Check failure of the harness between the Drum Unit (Bk) and
the DC Controller PCB (UN09/J25) (trapped cable, open circuit,
connector disconnection)
4.Check the Drum Unit Relay PCB (Bk) (UN29) (Soil/ deformation/
damage)
5. Check the Drum Unit Memory PCB (Bk) (UN33) (Soil/ damage)
6.Replace the Drum Unit (Bk).
7. Replace the DC Controller PCB (UN09).
8. Replace the Main Drive Unit
E022 0000 05 Title Error in detection of abnormal opening/closing of the Laser
Shutter
Detection At the Laser Shutter open/close control, the sensor fails to detect
although the specified time has passed (the specified time differs
depending on the mode)
Remedy Error in the Shutter Motor or the Laser Shutter Sensor
1.COPIER > FUNCTION > PART-CHK > MTR; move M05
When it works
2-1. Check the harness between the DC Controller (UN09/ J11)
and the Laser Shutter Sensor (PS05)
3-1. Check condition of the Laser Shutter
4-1. Check the Laser Shutter Sensor (PS05) in the Main Drive
5-1. Replace the Main Drive
When it does not work
2-2. Check the harness between the DC Controller (UN09/ J31)
and the Developing Disengagement Motor (M05)
3-2. Check conduction of the fuse (FU6) in the DC Controller
(UN09)
4-2. Replace the Laser Shutter Motor (M05)
5-2. Replace the Main Drive
