Receded all for Drum units and it's still getting code.
Originally came here for service call of poor copy quality.

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)

**(This is your likely culprit!! Check the drive gear on the rear of the Magenta drum to make sure it's not cracked!!)**



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

Probably a coupling problem if it makes a clicking noise... To check, boot with front cover open and push in the cover sensor. touch the M Drum, you'll feel it when it's clicking/jumping over the coupling...

I Hope it's the drum itself... replacing the main drive unit is quite a hassle...
