HP Laserjet III P problem

[Stefan Toftevall]

Hi everyone,
My good old laserprinter suddenly refuse to print with the display
showing: "50-Needs service". Anyone know what is wrong?
I heard somebody say it has got an internal counter, and after a
certain amount of printouts, it display this message though it must
not be anything wrong. The counter needs reseting in some way.
Anyhow, any advice is appreciated,
Regards, Stefan

This code indicates a problem with the fuser. This model series is
famous for an underrated capacitor in the fuser circuit causing this
code. I'm not a tech, but I'm sure someone here will be able to help
you further on this.

BTW, a simple check on google gives:

Sounds like a motor assembly, pretty common, its deep inside the
machine = $$$.

get another printer at ebay.com if you want a cheap one.

50 is a fuser error, there can be several causes but 99% of the time it's a
small usually green electrolytic capacitor on the board that controls the
fuser lamp (it's near the power supply). If you get that board out and look,
you may even find that the cap is leaking or bulging. Replace it, reassemble
and you should be good to go. Those are very good printers.

Yep as others have said

the fuser or the PSU cap = service 50

You can check the fuser bulb with a meter should read 20-30 ohms


Ref the counter and all that crap... thats on the larger range of Laserjets
ie laserjet 5si.. laserjet 8000 etc

That error means the fuser isn't getting up to temperature. It could
be a blown fuser heater lamp, thermal fuse, or the control circuit.

This site should have a repair manual for this. It should show you how
to disassemble and check the components...Do a search for Laserjet 3 or
such...
