I have an HP LaserJet 8150 which is displaying a 50.1 Fuser error,
which I tracked down to the Low Voltage Power Supply's 24V rail being
dead. I poked around the power supply a bit, but nothing is
immediately obviously broken. unfortunately, a replacement power
supply is about $250-$400. Are there any components on this power
supply that are common failure points I should specifically check?
Thanks!

I assume you've already hit the repair FAQ on SMPS repair?

Also with these beasts, IIRC, there's possibly some involvement from the
logic circuits telling the PSU to turn on certain sections. This *can* be
just poor ribbon cable connections or open circuits.

I am not sure where you are, but in the US a refurb C4265-69006 power supply is
available from HP for $101 with return of the bad unit. See http://partsurfer.hp.com/cgi-bin/sp...e=main&cpric=&psrchmode=&partsrch=C4265-69006 or go to http://partsurfer.hp.com and search for the LaserJet 8150.

that route. Thanks!

Also, can anyone reccomend a good site on preventive maintence on these
printers? Unfortunately, service contracts were allowed to lapse on
these printers and I suspect these printers have been neglected, so I
would be interested in any tips/maintaince we can do (other than the
obvious of installing maintaince kits) to help keep them working well.

Apart from the maintenance kits there is very little service needed on these,
the kits are recommended at 350,000 page intervals and you will need to reset
the counter each time you fit a kit. This printer is inclined to dump a little
toner which can be picked up with a dry lint free cloth easily, and they
generate paper dust just in front of the transfer charge roller, worth
vacuuming that out on a regular basis otherwise just clean up any dust or toner
that is sitting inside the printer cavity.
