HP LaserJet III: manual and power saving?

[John Smith]

I recently became the owner of one of these beasts and it still runs great.
I've been trying to find a manual for it, but no luck so far. The HP web
site doesn't seem to have it. I read on HP that the printer uses 170 watts
in standby mode. From the front panel I can't find a menu reference to a
power saving mode.

Does anyone know where I can find a manual? Does anyone know if the
LaserJet III has a power saving mode (other than the 0/1 switch)?

TIA.

T'isn't one.

We are still using the HP LJ III that we bought on July 27, 1990 for
$1,874.50. How I know in such detail is that we were clearing out
years-old boxes of detritus and came across the canceled check we wrote
to buy it. I taped the check to the top cover.

It is our primary printer -- tho', we don't print all that much
now-a-days. I save $$$ on toner cartridges by shopping at The Salvation
Army, ARC, Goodwill, etc. When other folks get rid of their LJ III's,
they donate their unused toner cartridges (I assume.) Haven't paid more
than $10 per cartridge in a decade or so, and I have maybe a 4-year
supply on hand now.

Just the ON/OFF switch. Not that much of a hassle in our 1-room home
office here.

I have all our original manuals -- plus a couple more technical ones
that were bought along the way. So, I have no knowledge where you might
locate these. Hopefully, someone else here can point you in The Right
Direction.

Our back-up printer is an HP LJ 4 -- which I bought at a second hand
store for $7.50 some 8-9 years ago (Wednesday was "Half-price
Electronics Day")! The LJ 4 _does_ have a power save / sleep mode.
I have been getting its toner cartridges the same way as the LJ III's.

So, my cost average for our 'printer farm' works out to be $940.00 per
printer. Pretty good for 1990 dollars.

I know what you're talking about. I usually buy HP 5L per cubic metre on
ebay, and use the cardridges for my 6L

Sadly no power saving mode.

I would look online for a manual. But I do have one that I would send
for the postage etc. I would imagaine you can download one somewhere.
So the choice is yours.

I have a couple of IIIs I will be dumping but they are costly to ship.
Probably 30 or more.

Printerworks.com for parts and anything else you need.

I have a IIID and a second one for backup. I use the IIID daily. Love
the duplex feature.

This printer does not have a power save mode. The first printer to have
one was the Laserjet 4.

I actually do have a manual for it, but I don't have any good way of
giving it to you (e.g. it's a printed manual, not a PDF file). In fact,
it's still shrink-wrapped. The HP 3 was a Canon SX engine (same as the
Laserjet II), but the controller was enhanced to add "RET" (resolution
enhancement technology). Other than that, the HP II and III are very
similar.

Not really true. The HP LaserJet 4 did not have a power saving
mode. The 4L was the first printer to have the Power Save mode. You
may be thinking of the LaserJet 4 Plus which did have the Power Save
mode. The first incarnation of the 4 didn't have it however.

Great tanklike 300 dpi printer. Uses a lot of electricity; cheap to feed
otherwise. But there's one serious problem: it spews out a lot of ozone.
There is an ozone filter, which many people in the printer business have
no awareness of. Further, on the aftermarket, most ozone filters are
junk and will work only for about a day. I understand that there was/is
one source of decent ozone filters someplace.

Mine was an HP II retrofitted with an HP III board. The ozone problem
was so bad that I could only print if I had a window open.

One of the things that I really like about it is that the paper path is
accessible, so you can clean it easily and clean out ripped paper
properly. These days, this is a big deal. But the ozone problem's a killer.

Actually, you are correct in that I'm basing my comment on a Laserjet 4
Plus. So you may be right about the original Laserjet 4 (both printers
used the Canon EX engine and look and largely are identical, but there
are some differences ... including a speed increase from 8ppm to 12ppm).

 

[Barry Watzman]

Some people are sensitive to this, but I never had a problem with it (in
this or any other printer or copy machine) and neither did anyone that I
know.

[The ozone comes from the transfer corona. More modern printers and
copiers don't have one, and thus eliminated the entire issue (they have
a transfer charged roller instead of a transfer corona).]

Thanks for your help. I still haven't been able to find a manual, but now I
just turn the printer off as soon as I'm done printing.

... I still haven't been able to find a manual, but now I

That's what we've always done here with our HP LJ III for the
last 17 years. In the Winter we may leave it on after a print job to
help heat the room. Not so in the Summer!

Zippo for maintenance in 17 years -- just a vacuuming and toner
cartridge replacements.
