HP LJ4 Problem. 50 Service, error message

[Guest]

Can anyone kindly help with a '50 - Service' Error Message?

The m/c has given me a couple of years of perfect service but suddenly,
today, this message keeps coming up. Nothing appears to be wrong externally,
it starts its self test and warm-up, but then this message appears.

If I check my list of messages it says 'Call the HP service engineer' but
that is not what I really have in mind!

Is there anything that I can check myself?

Many thanks in anticipation.

Eric

It's a fuser fault.

It could be the thermistor, or the lamp (most commonly).

New fusers aren't cheap but are trivial to fit (5 minutes max). Look on
eBay as they occasionally appear. Lamps are cheaper ($20 or so) but take
a bit of time to fit into the fuser. It may well be that if the lamp is
knackered so are the rollers, although I fitted a new lamp to a
28000-pages printer and it's now over 70,000 pages (a younf=gster in
LJ4+ terms).

Email me if you'd like more detail.

I had one stripped down yesterday for a major cleanout. I got a "50 -
service error" when I accidently forgot to plug the leads back into the
laser assy.
