Hi,
There should be a number of precision shafts,
some with rubber coatings. But it all depends on
what you do and what you need.

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.

Why are they throwing it away? If it's repairable, it's probably
worth more as a printer than as anything else.

If it's a paper jam problem, see this link:
http://www.fixyourownprinter.com/kits/hp/12

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.

We hauled five of them to the landfill a while back and had to pay for them
to take the heavy suckers. All were working perfectly.

Your local thrift will often take these if working.

Do pass the word around about http://freecycle.org/

"The worldwide Freecycle™ Network is made up of many individual groups
across the globe. It's a grassroots movement of people who are giving (&
getting) stuff for free in their own towns. Each local group is run by a
local volunteer moderator (them's good people). ...

One main rule: Everything posted must be free, legal, and appropriate for
all ages. ... "

I didn't bother to ask the question you are asking. I simply tore down a
couple of obsolete printers
and kept what looked interesting.

When a third printer came along, I simply trashed it, along with most of the
parts that looked "interesting"
from the first two printers.

Hope this helps,
Ace

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.

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.

A 5SIMX with PostScript, duplexer, and a hard drive remains an excellent

The regular 5Si ain't all that great.

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.

That's the real answer.

I still have a cigar box of parts from an old Wang word processor circa
1967 laying around here somewhere. Lots of interesting stuff in there.
I kept most of it in bigger boxes that gradually got thrown out until
all I have left is the cigar box, mostly odd springs and metal screws.

I did not use a single part from that Wang in oll the time I kept them.
Not a spring, not a screw, not a shaft or a motor or a washer.

Yep, they are good for that, but you'll be very hard pressed to find one

printing a lot of pages would have used a LaserJet 4. I've had some that
exceeded 400,000 total pages. The LaserJet 4 was the only really reliable

See the many tutorials on my website.

Pen plotters are useless. Pen plotter motors are useless.
But heh heh heh laser lightshow galvos fly on outta here.

Relay racks are unsellable at any price.
But heh heh heh their drawer sliders resell for sixty bucks a pair.

Water soluble swimsuits are very much in demand by quilters and felters.
Astronomers snarf up voting booths as fast as you can offer them.

Precision ways and sliders sell for outrageously high prices.As does
robotics anything.

Monitors and TV's typically have a good assortment of power semiconductors,
not to mention all sorts of capacitors and other parts. I tend to pull the
boards out of anything I scrap and salvage parts from them as needed.

Using a 6 mp here too. Getting on 8 or 10 years old and still going
strong. Also, the toner seems to last forever and the drum rarely needs
replacing. FAR better than some other printers around here that scream
for a new drum and toner what seems like every other week. I hadn't
thought about it but I should search for another one used as this has
been about the only printer that I feel has given me more than my
money's worth over the years.

A note on the original post about salvaging parts from old
printers...Many years ago when electronic calculators suddenly became
affordable, Boeing Surplus started selling the old monster mechanical
calculators for a buck a piece. I was about 12 at the time and a buck
for one of those 80 pound boat anchors kept me busy for a couple of
weeks after school disassembling and scrounging cool parts. I learned
more about assemblymethods and general mechanical stuff from that than
just about any other source.

I know that old printers/copiers are cheap as dirt (free often) and can
be used the same way, although they don't have quite as many parts as
those old calculators. I've had my daughter take apart a couple of
similar things as a learning experience (help dad by salvaging parts).
Any other ideas on cheap mechanical junk that is readily available and
may be a great learning experience for the mechanical kid to monkey
around with?

Anything. My #1 son is a "take apart junkie." he takes his wagon out
bright and early every monday morning to find stuff to bring home and
dismantle. We've done toasters, VCR's, tape recorders, toys - all kinds
of stuff. Last week we did an aqua-pic and a hose sprayer that had an
adjustable flow thingy. A 35mm camera was cool - about a gazillion parts
crammed into a 3 x 5" box. Amazing to me, who can't seem to even fit all
our clothes into the closet.

If you've got no pride, just pick up anything but a TV (unless you know

Nonsense. It's not the lead that's dangerous, it's the tube which might have
a charge although that's most unlikely. A quick whack with a clip lead will
empty that. 1 minute after, maybe. 6 months, no way.

Depends mostly on the quality of the rectifier, and on whether there are
any bleeding resistors or voltage dividers. Give a vacuum type HV
rectifier and no bleeding resistors it should be easily possible that a
picture tube retains high voltage for weeks.

A while back I read in a tabloid about a man who had a nasty accident
after he left a bar drunken in the early hours. He was walking home with
a few mates when he needed to relieve himself. His mates dared him to
pee off the parapet of a railway bridge, which he did. Apparently his
stream of urine hit the 25 kV overhead wire which supplied the trains,
and he had a difficult job explaining the situation to a doctor at the
hospital when he came to.

My parents had to hide the screwdrivers from me...nothing was safe from

I predict that your son has a great future and an interesting life

If I were his parent, I would be very proud of him.

I'd do it, I pretty regularly touch flyback HV leads, there's nothing in the
flyback that can store a charge, the tube itself does that. A B&W monitor or
a vacuum tube TV chassis can hold a charge for quite some time, but a solid
state color set has a focus divider that'll discharge the HV within minutes.
It's still always wise to ground the anode just in case though.
