RICOH MPCXX04/04ex squeaking

[enricos]

Hi everyone,
I noticed that various multifunctions MPC 04 and 04ex series, after some months of work produces a high and annoying squeak from the right side (duplex). I've tried to switch the entire duplex with another one (used), transfer unit and the itb unit. Does anyone have any ideas?
Thank you

Have you run output checks to ensure it is the duplex?

Usually squeaks come from the PCU when they are near/past PM life.

Black PCU,run in output mode

Exit assembly.

As mentioned above, it's either your K PCDU or the ITB unit.

Also at mentioned above run the output check on the K drum dive/transfer motor
