    MFC-L6900DW Print unable 0B

    Today got call from a client with message - Print unable 0B.
    Manual is vague about this type of errors(there are 2 of them - 0B01 and 0B02) and in both leads to change of HVPS or Main Board(PCB).
    After little Google research decided to go with new Drum unit and BAM that did the trick. Kinda bad old drum unit shorting out high voltage PS.
    Tip: Always use Service Manual, Never underestimate Google search
    A tree is known by its fruit, a man by his deeds. A good deed is never lost, he who sows courtesy, reaps friendship, and he who plants kindness gathers love.
    Blessed are they who can laugh at themselves, for they shall never cease to be amused.

    Nice Catch ... but that is pretty common...

    can't remember the 'Unable to Print' code.. but it referred to Toner - Clean Drum Corona ... but 9/10 times it was the drum unit OR drum set on some of the lower rated color MFP's.
