MX-M364N F2-78

[boutn]

We have an MX-M364N that keeps throwing F2-78.

Sensor on the transferunit has been cleaned, FWupdate done, laserunit cleaned...

Any other suggestions?

Clean the connection between the right side door and the engine.

If this does not work then I suggest replacing the transfer roller unit.
