Were they obviously dirty?
Did you clean the laser lens?

They were just detectably dusty.

I cleaned both of the large lenses, the optic just after the laser diode
module, dusted off the scanner mirrors, and blew out any dust on the long
turning mirror. There is no window on the output (I seem to recall someone
mentioned something like that).

This is a LaserJet 5, C3916A.

Thanks guys, it's not worth the time to do more to this 12+ year old printer.

Yeah pretty stupid that alll the 5x printers I've worked needed just a

hell you probably designed and built them yourself right?

You *are* an asshole, aren't you?

Just checking.

No, they don't.

Ah ok so a 5/5n/5blaha have different engines. Gotcha.


Looks to me like the laser guts are dirty and the optics need cleaned.


One of several possibilities. That's like claiming every defective

I really hate satisfied customers. It's really bad for my repair biz.

Is it an HP 5M, 5P, 5L, 5N, or 5Si. They're all quite different.

LaserJet 5

Ok, EX II series printer:
http://www.printerworks.com/Printers/LaserJet_5_5M_5N.html

In this case I tend to agree but might explore the scanner assembly, probably
after I get a new printer!

You might be able to get away with just a (dry) air hose cleaning. The
laser slot is at the top of the printer. Remove the toner cartridge
and you should see the slot. There's no window. Just blow some (dry)
air into the slot and hope that it removes the dust. I would give it
about a 30% chance of success. If not, remove all the plastic outer
case parts. When you get the top off, you should see the laser
scanner assembly. No need to remove it. As I vaguely recall, the top
is held on with one screw and some simple snaps (not sure). Once the
lid is off, clean the haze off the optics and mirrors.

I once had a customer with about 10 laser printers including several
HP5m models. Some of them required cleaning the scanner optics about
twice per year. It took me a while to figure out what happened. They
were using refilled toner cartridges. The cart vendor was applying
stickers onto the cartridge that eventually would just fall off. I
was wondering where the glue went. I eventually suspected that it was
being volatized and was coating the inside of the laser printers,
including the scanner optics. Wiping down the inside of the printer
and finding a thin sticky layer confirmed my guess. I told the
vendor, who initially thought I was nuts, but eventually thanked me
for solving a running mystery.

OK, well, cleaned the two large lenses with isopropyl, dusted off the scanner
mirrors, blew out the long mirror. Basically, no change.

Time for new piece of junk printer, but that should be adequate for my needs.

Thanks!

FWIW, I got, off of eBay, a really nice Xerox 5400 40 PPM duplex laser
printer the other day. Incredible performance, had about 33K copies on
the counter. Price? Well, 49.95, and I was able to pick it up and save
on shipping. I didn't complain about the fact it came with a brand new
toner cartridge, either. I still laugh whenever I look at it. <bg>

There are some good deals on higher quality printers right now, as
companies either upgrade, or go out of business.

Sam, I think he's asking:

LaserJet 5M?
LaserJet 5P?
LaserJet 5L?
LaserJet 5N?
or
LaserJet 5Si

Nope. Some are totally different.

I'm jealous. Nice buy. The problem I have with Xerox printers
(mostly Tek color Phaser models) is getting parts. Xerox does not
make it easy for independents to buy parts and pieces direct:
<http://www.xerox.com/go/xrx/template/018p.jsp?Xcntry=USA&Xlang=en_US>
I can get most of what I need from recyclers and eBay parts cannibals,
but it's MUCH easier with HP products, where original parts and clones
are common and cheap.

Shipping on large printers is usually the problem.

My favorite printer of the week is the HP2200dtn. They're fast,
duplex, network ready, and most important for me, don't make any noise
or suck power when in standby. About $100 to $175 on eBay. I
obtained a pile from the local recycler for about $25/ea. One problem
with the HP2200dn is decomposed foam on the solenoids causing paper
jams. Here's the fix:

That's more than we need to know. :(

He presents himself as an expert, then screams when someone points
out an error. No, I haven't done tens of thousands of laser printer
repairs. The total is close to 100, but I am working on older printers
no one else will touch around here. I currently have about 15 laser
printers waiting to hit the bench, and about 150-160 inkjets and a
couple dot matrix. I repair them, just for the hell of it. I do look at
all the models with similar numbers so i am familiar with them. I have
a database of what is waiting for repair and like to have at least three
similar units so I can be a little more efficient. Then I can scrap any
not worth repairing and sort out the good parts.

I was put on 100% VA disability a few years ago, but I need a hobby
to keep my sanity so I don't start posting like Meat Plow. :)

I picked the 5400 because I already have a GCC XL-40, which is the
same print engine, just different software. That made two of them, but
the GCC didn't have duplex. Then after getting the second one, I
figured 'spare parts would be nice'. OK, found a third one for $20,
and that one did have a duplexer. I pulled the duplexer and put it in
the GCC, and kept the rest fo the $20 printer for parts.

(The $20 printer was heavily used, so I didn't feel bad about parting
it out--the thought of cleaning it was too much! And I didn't need
three printers, either.)

I know it's cheating, but I bought a $99 HP P1006 on-line and it is actually
perfect for what I need - small, light weight, trivial install, decent print
quality. I know it will probably fall apart in a year from loneliness given
the amount of printing I do - mostly mailing labels and tax returns. :)
Between now and then maybe another friend will dump off a half-working printer
at my door step. :)

Thanks for all the comments!
