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
