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

I did not know HP will swap it out for only $101. We're going to go 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.
