Hp HP LaserJet 5MP

HP Laserjet 5MP

My HP Laserjet 5MP prints black pages. When it is left on for a long period of time (maybe 2-3 hours)it prints fine. Can anyone please help me with this problem. Thanks
Are there white borders or is it solid black?

Solid black

That would mean it's not generated by the printer logic. This narrows it down to high voltage. It would have to do with a loss of high voltage to the cartridge drum. Normally it would be a bad contact issue, but the warmup period woud argue against that. I would just leave it on all the time as it doesn't consume much power at idle.
