HP M3027 prints solid black pages

[psteelers]

Hi all. Had a fellow tech inquire on a HP M3027 that prints a solid black page when trying to print a config or any other page. He has tried a second toner cartridge with same results. I'm looking at it tomorrow for him. I suspect either a broken contact spring to HVPS or a bad HVPS.
Is there anything else you all may have run into that would cause this?

Thank you.

Poor cartridge drum ground contacts. Similar to the P3005 series.
