    I agree with the above post that the cyan belt charge roller is loose or the grounding spring is not positioned correctly.
    I seem to recall a new transfer belt that had one of the charge rollers fall out before it even came out of the box. I don't remember the symptom though. =^..^=

    If you'd like a serious answer to your request:
    1) demonstrate that you've read the manual
    2) demonstrate that you made some attempt to fix it.
    3) if you're going to ask about jams include the jam code.
    4) if you're going to ask about an error code include the error code.

    Typically it will not calibrate and lead to errors "Sub Cyan xx front/rear".

    Cthulhu for president! Why settle for the lesser evil?

    just to be clear when you say you change out the "drum" you are replacing the whole pcu right? because it comes as a whole on that model. 'mx-c40nrs'. Interested in this fix, let us know what you come up with.
