I still have some parts for the original LaserJet. If I recall
correctly, the engine was made by Canon and was also used in printers by
other manufacturers like QMS and Canon. I installed & maintained quite
a few of them.
As far as collecting printers, I still have a few that are small enough
to hold onto. I have a Kleinschmidt drum printer (1960's?) and an
Axiohm aluminized-thermal printer from the late 70's. I had to give up
all my Teletype's (ASR-33 and an older model) as well as a chain
printer, Printronix line printer, and a wet-process "laser" printer from
the early 70's (?) I think it was a Xerox. Just took up too much space.
They are all a part of history; I hope someone out there is holding onto
them.

Owned by a coworker of mine who says it still works fine.
He doesn't want to throw it out if there is someone
interested in preserving it. Somehow, I've never been
interested in adding printers to my collection. In the
"nostalgia era" of my computer experience, what I collect,
printers were noisy, messy and not worth the bother.
Anyway, if you want it and can arrange to pick it up fairly
quickly, let me know.

Yes, it was the Canon CX engine. Canon sold the CX-VDO mdoel with no
formatter board ('video interfacve') and the LBP8A1, etc with their own
formatter, Ohter manufacturers made their own formatter boards. Actually
the HP Laserjet used the Cannon formatter board with different firmware

Bieign a hardware collecotr, I colelct things other than just computers,
and as I've said before I can find beauty in a printer (or a modem, a
terminal, etc) as well as in a processor.
I try to colelct machines that are in some way unusual (which actually
covers quite a lot of them :-)). Amongst them I have :
A few mechancail teleprinters (Creed 7E, Creed 444 [1]. Teletype ASR33)
A Versatec V80 electrostatic printer
Canocn CX laserpiner (heck, an SX engine, in the form of an Apple
Laserwriter, is the main printer here).
An HP 7245A thermal printer/plotter. A strange machine, it both prints
(using a 712 element printhead) and plots (using one element and moving
both the prinhead and paper back and forth).
A Centronic printer that seems to move the carriage by havign a
contiuously moving belt running acrsos the chassis and solenoids in the
carriage that grip eiterh the top or bottom run of the belt to move the
carriage in either direction)
That Oivetti Sparkjet (JP101) I mentioned a while back
HP Thinkjets (I think I have one of every model now).
ICL/GE 'Termiprinter' A priting termianl that is actually a belt type
line printer inside.
And of coruse assorted impact dot matrix printers, daisywheels,
spark-onto-alumiium-coated-paper printers, numerical strip printers, etc,
etc, etc.
[1] I don;t suppsoe anyone knows where to get a reader drive belt for
this machine from? As far as I rememebrr it's the same pitch as the mtoro
belt in an ASR33, but that one has 44 teeth and the Creed 444 4needs a
shorter one (40 teeh? 41 teeth?).

are unobtainable now.
Try cartridges for the copier CANON PC-1. If you don't find and need
some, drop me a mail that I maybe can find some here.

I remember pretty clearly that the PC-1 copier cartridges are
physically identical, but they don't work. The composition of either
the drum coating or the toner is different.

Strange, they use even the same engine, why woulnd't work? ;oO

CX laser printer engine uses a laser diode (I don't recall if it is
visible or infrared) to scan across the drum, while the PC-1 photocopier
uses an incandescent lamp to illuminate a strip across the page as it is
scanned. The wavelength and amount of radiant energy involved are
completely different.

This is something I didn't though...Thanks for shedding a light on the
subject, Dave!

It is my pleasure.
I would love to give this old Laserjet a home, and (as I mentioned to
you in private mail) I will be in that part of the country for a while
starting in a few days. I wonder if it will still be available.

Not quite.
I do not know the specific differences, but, I do know that if you put CX
toner in a PC10 copier cartridge, you get a white on black image, but not
a clean one - it vaguely resembles solarized photos.
CX also makes vaguely round dots "inscribed" in a rectangular grid, that
do not overlap [much]. You can not get a really good black.
On the SX, which is a engine that is much different from the CX and PC
ones, the dots are larger, and overlap, so you can get a much richer
black.
