LaserJet II Turns Off and On Intermittently

My Laserjet II has ground out about
200,000 pages with one overhaul. About
3 months ago, a numb-brained
secretary left a stack of papers over
the output vent on the right side on
a Friday, and simultaneously accidentally turned on the printer. Despite cooking all weekend, the printer seemed to work fine. However,
over the last few days, it has started
turning itself off and on. That is,
with power on, a variety of strange
symptoms occur, including the all indicator lights turning off and the
LCD screen going blank. Now here is the
strange part. I find that, if I open
the top of the printer slowly, the
lights turn back on as the door moves
halfway up.

Even more strangely, I pulled the paper
tray out, restarted the printer, and
it powered up normally, saying "Paper Out." I put the paper tray back in,
and the printer worked fine for about
an hour.

I overhauled this printer once 3 years
ago and paid $330 for a new fan, fuser,
and general cleanup. This printer has been a workhorse, and seems built better than the 2100M I'm contemplating. Should I try to fix it?
Any ideas what is happening?

Thanks,

Jim

Jim, I haven't worked on too many II's or III's lately, but I did have a rash of overheated DC power supplies with bad solder joints. Some of the power supplies I saw were quite toasted. Maybe a failed upper fan contributed, or as in your case, a blocking of the air vents.

Thanks, Raymond:

You hate to junk a printer that is the size
and weight of a small battleship, especially
when consumables are so cheap and so widely
available.

Guess I'll try to revive it one more time.
