HP LaserJet IIP simply quit

[Gene]

My HP LaserJet IIP simply quit running. It was sitting on the desk turned
on with the on line light lit and when I walked into the room a short while
later it was dead. Tried switching in on and off a couple of times and of
course made sure it was plugged in. Opened the front and the area where the
toner cartridge goes and enclosed but the printer did not respond. It is
totally without power as no sound is emanating from it. Is this a known
symptom of a problem and if so where do I start to troubleshoot it ? I can
do some basic repairs if given a little guidance. Thanks........

Try checking the fuse in the power supply. You have had a brown out
in your home and it could have blown. Just a thought, always start at
the most logical point is what I say.

Clicked on the switch this morning and the printer started up again.
Printed a test page and it looked great. Left the room and came back about
15 min's later and the printer was dead again. Tried to turn it on and off
but no luck. Now about 5 hours later still no luck so something is wrong and
intermittent so I'll try and get the case off and see if I can spot any
components that 'look' bad. Thanks for the idea's.

It does sound like the power supply as Don suggested. But have you tried
another power cord?

Sounds like the power supply might be on it's last legs. We just had a
supply in a VME system go in a somewhat similar manner. Turned the system
off to reboot it, would not turn back on. Later that day (after pulling the
whole VME chassis from the rack) the power supply powered up when turned on,
but after being turned off, would not come back on. Next day, it powered
up, but again would not turn on after being shut off for a few moments.

One poster to my problem suggested (and I tend to agree) that the
electrolytic capacitors in the power supply were drying out. Don't know if
you are into swapping electrolytic, or if IIp supplies are readily
available.

I metered the power cord wiggling it around as I held the probes to it and
all seemed ok, but I will dig up a substitute cord and give it a try.
