Developing screw rotation 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

You might need rail assembly FM3-8110-010 for Cyan.
