At my work, they are throwing away a HP LaserJet 5SI printer. I am thinking that perhaps there is something valuable here, like stepper motors or whatever that I can salvage for my "projects". Any suggestions?

Thanks. I already have more bearings than I would like to admit. The rest does not seem very worthwhile, given that taking the printer home is difficult (I take train to work).
I have no idea what I need. With the military surplus stuff that I throw away, my standard procedure is to take out all motors and screws and switches and large semiconductor devices. Given the excellent webpage suggested by someone else, there is little truly worthwhile stuff in that printer.
Given what they get for refurb and pulled parts for these printers, a computer parts recycler would probably pay a not inconsiderable amount for the carcase, even if it seemed totally dead. Some places, tossing computer parts in the trash will get you in legal trouble. I've never actually tossed an HP laser printer, they've always been revivable with a little effort. The paper trays alone are worth a bunch.
For parts of interest, you've got a laser in there, some kind of scanning mirror and motor, rudimentary optics, gears and bearings, a power supply with semi-HV output. The sum of the individual parts and assemblies is far more than the whole works costs.
The whole printer itself, if in working condition, is quite valuable. I'd grab the fusor assy. from a few just for insurance along with the ozone filter and then a couple of full working units for home. Also, any toner cartriges are going home too. I've got several of the older LJ2/3 units and they have been very good workhorses.

Probably a couple of nice steppers, if it's got a duplex unit maybe a couple more, loads of gearwheels, a few solenoids maybe a synchronous belt and associated pulleys, the drive electronics for said steppers and solenoids and my favourite bit, a laser scanner assembly with some nice quality mirrors, lenses and a nice rotating mirror (could be hexagonal, octagonal or a twin faced unit) The PSU's (HV and DC) *might* be useful to you but I'd be surprised.
We find that the old 4100 and 4200 series printers are currently the best HP printers. The 5SSi is nothing more than a dinosaur that takes up too much space. Make an attempt to find a sucker locally for $100 cash or toss it.
