I would try a formatter first.

I had one of these hit by a storm and not power back on. I replaced every single board in it, and still nothing. I believe one board was knocking out another board, and the only way to fix it was to replace all of them at once, instead of one at a time. I gave up, and told the cust it wasn't worth the effort. I lost money on that one.

it's the logics of the printer.. converts data into print .. the DCC is what take the DC power and sends it to motors / switches / sensors .. LVPS converts AC ---> DC power... HVPS takes the DC and shunts it to the contacts for toner/drum/transfer rollers

can you print the config page? does it give any errors? if so what?

do they have it plugged straight to the wall? DO NOT plug a laser printer into a battery backup.. it can kill the battery and CAN cause problems like you are seeing.
