B554e prints nothing, copies nothing.

Drum and Dev changed as were due. no change.

Drum confirmed to rotate.
Stop mid print and no image on Drum

Load checked Laser (Print Head) and it spins up, so think thats fine.

Get no C codes just P codes due to failed stabilisation.

Im thinking either Print head or HV Board

Under time pressure to solve this, im thinking the HV Board, do you concur

thanks?

If you had the transfer belt out I would make sure it is installed correctly.
Also check that there isn't something physically blocking the printhead.
HV board, as you stated, could also be the culprit.

no data to the print head does this on some KM machines

I hope you have re-seated HV and PH connectors already. If no result, try changing 1 by 1.
No data to PH is Worst case.:(

In my experience a bad HV board causes washed out prints not completely blank. So good to know, thanks.
