Hi,
I've got a Laserjet III that's intermittently throwing Service 50
errors. Fusing lamp tests good as per
<http://www.fixyourownprinter.com/reference/guides/fuser/sx>. I assume
this means the AC power module has fried itself.
Does this happen randomly throughout the day? Or, only
when the printer is first powered up?
Best I can find on Google is that I need to replace
the triac and some
'support components'. I can find component designator IDs, but not
component values - does anyone know what needs replacing, and what to
replace it with?
It's also been throwing 13 Paper Jam errors, but there's no paper jam
visible. Anyone know what causes this? I'm guessing the optosensor on
the fuser assembly has failed, but I can't identify the opto. Does
anyone have a part number for it?
I can email you a service manual...
Finally, if by some twist of fate I manage to get
this thing running,
I'm going to need an A4 paper tray. Anyone in the UK got a spare they
feel like parting with?
