My friend is willing to give me his B&W laser printer:
HP LaserJet 2100TN

It still works but he says it does not print as dark as it used to.
Here is what he says.

Do you think, based on this, that the fuser is bad?

Here is what my friend wrote me just now:


Hi Misha,
Do you want my HP LaserJet 2100TN? It works ok but prints light.

Im guessing the fuser would need to be replaced if you want it to print
dark although a new toner cartridge might also work. The printer says it
has printed 37k pages and the fuser has a life expectancy of 150k pages
so there is definitely life left in it. I was considering replacing the
fuser myself €“ you can buy fusers for about $30 and they are very easy to
replace on this model. But it just doesnt make sense for me to invest
in this printer any longer

It has had the occasional paper jam but otherwise it has been great. It
has two trays that hold about 500 pages each, 24MB of memory, and a
Ethernet port. I still have some toner cartridges left but I dont know
how much toner is in them.

Fusers almost never cause light printing and on the very rare occasions that
they do they cause ghosting down the page.
Far more likely that it needs a new cartridge, bear in mind that cartridges
that have been in storage for a very long time can print light.
If the light printing is not across the entire page, cleaning the scanner glass
may improve matters. Failing that you may have a failing transfer roller (or it
may not be making good contact in its housing) but this is not common.
A new cartridge nearly always fixes light printing.

Misha-

I think you can probably get the printer to work, and it should be a
workhorse.

It is my understanding that the fuser heats the printed page as it
passes through the printer, melting the toner into the surface of the
paper. If the ink does not rub off after it leaves the printer, the
fuser may be working correctly.

If printout is light, it could be caused by lack of toner, or the
photosensitive "drum" could be worn out. Some laser printers have the
drum in the cartridge, so a new cartridge would have a new drum. I do
not know about that model, but it would only cost you the price of a new
HP cartridge to find out.

I found a service manual at
http://www.lbrty.com/tech/Manuals_HP/2100sm.pdf. Its troubleshooting
section may be helpful.

It's not the fuser. The fuser is a quartz tube "lamp" that heats the
fusing roller - which melts the electrostatically deposited
polymer/carbon toner into the paper. Either it works or it doesn't -
(or just doesn't get hot enough) the toner smudges off the paper. If
it fails totally the printer shuts down and gives an error code.

I've replaced fuses on printers a lot older than that because it made
good economic sense - but this was on heavy duty printers like Series
2 and LJ4000 printers.

A 2100tn would be worth rebuilding the fuser on IF the fuser was the
problem and you are handy enough to do the labour. The tube itself is
cheap. A rebuilt fuser is only about $55 - $85.

I've bought the bare tubes for $30

Hi,
Fuser is a heater which put the ink particles bond to paper for good.
I think the printer drum(where image is formed) is going.(usually a part
of toner cartridge) when image comes out light.

Misha:

I would take the 2100TN down to any place that rebuilds laser printer toner cartridges and ask if you can try a rebuilt cartridge in it to see if that solves the problem. I expect it will.

I thought the fuser was the heater that melted the ink particles so
they became liquid ink and stuck to the page. Tony seems to say the
same thing.

When the fuser isn't working the ink comes out llike dust on the paper
and you can shake it off or blow it off. When the fuser isn't
working at all what you get looks like a blank sheet of paper. I
sort of think it's not possible for the fuser to be working but not
well so that it gives a light image.

When I had a laser photocopier, made around 1978, the thermostat on
the fuser was broken, and like I said, it looked like the page had
printed, but all the ink fell off when I took the paper out of the
tray, or blew off when I blew on it.

I have a B&W laser printer and it's nice that there are no little
holes to clog or dry out. And that if I don't use it for weeks or
months, it's still the same.

Mine has two settings, light and regular. Maybe yours is set wrong.
Mine has gotten a little lighter lately, but I haven't investigated
it. After it wears out or when it needs more toner, I'll switch to my
dentist's printer. It was out in the hall waiting for the janitor to
throw it away when I came for an appointment a year or two ago. They
said it worked fine, but they were upgrading the computer etc.

most laserjets that I've had had software (or at least a control panel

control panel and also checking to see if there is still a downloadable

Here is a picture of the HP LaserJet 2100TN hooked up at my house:

I plugged it into the router by the ethernet cable, but, nothing
happened on the WinXP PC connected to the same router by ethernet
cable.

Probably I need drivers, but, when I went to the HP support page,
they had tons of drivers. But which one is the one needed to enable
the WinXP PC (and the other PCs connected wirelessly to the router)
to see the printer?
http://i42.tinypic.com/2ro52ty.gif

Which of these drivers will make the ethernet work?
1. hp LaserJet 2100 PCL 5e Printer Driver
2. hp LaserJet 2100 PCL 6 Printer Driver
3. hp LaserJet 2100 PCL 5e point and print bundles
4. hp LaserJet 2100 PCL 6 point and print bundles
5. 3 - HP Universal Print Driver for Windows PCL5
6. HP Printer Administrator Resource Kit

And, which of those makes the scanner part work?

I may have inadvertently misled you. The scanner I referred to is the one that
is part of the print engine, the LJ2100 does not scan documents.
I assume there is a JetDirect card in the printer, if not you will need to
either add one or use a print server if you want to network the printer over
Ethernet.

I had never heard of a "JetDirect", but, clearly the printer has
an ethernet port as shown in this picture below:
http://i43.tinypic.com/1oosug.gif

Also, the test pages that printed show under "General Information"
1. HP JETDIRECT = J3110A
2. PORT SELECT = 10BASET
3. I/O CARD = READY
4. SNMP SET CMTY NAME = NONE
5. TCP/IP STATUS = READY

Kewl! Thanks. My 3200m has two problems that I need to fix.

One is that it grabs too many sheets of paper in the fax feeder, making
multi-page faxes or copying impossible without hand intervention.

The other is that it streaks the paper with toner (so something must
be dirty).

I'll check out the service manual to see if it handles those two problems.

You can get a new laser printer for as little as $100,
multifunction, ie copier and fax too for maybe $150.
I would consider that for sure before spending money
on stuff that *might* solve the printing problem on

http://www.printerworks.com/Catalogs...ay2PickUp.html

Perce

Buyer beware.

The same thing is happening in the laser printer business as happened in the ink jet printer business over the past decade. Ink jet printer manufacturers were practically giving their colour ink jet printers away, or selling them for $39.99.

That's because colour ink jet printers ate cyan, yellow and magenta ink like a horse eats alfalfa, and a new colour ink jet cartridge would cost you $79.99.

Printer manufacturers had discovered that they can make more money selling the ink for their printers than they could selling the printers themselves.

So, nowadays you can buy a new laser printer for $129 instead of $429.

Beware that the toner cartridge in the $129 printer has a microchip on it. That microchip tells you when the cartridge has printed the estimated number of pages that cartridge should be able to print. Once that number of pages has printed, the chip shuts the printer down.

Before, with the $429 printer, you could take the cartridge apart, empty out the waste hopper bin, dump the unused toner out of the supply hopper bin and refill with new toner. Put the cartridge back into the printer, and you're good to go again.

Now, with that chip, you can't do that anymore. Now, you have to buy a new OEM cartridge or a rebuilt toner cartridge with a new chip in it for anywhere from $50 to $150.

So, what looks like a great price is a wolf in sheeps clothing. It means that you no longer have the option of refilling the cartridge with toner. Unless you also replace that chip with a new one, the refilling won't work. The printer won't print a page unless and until there's a new chip on the toner cartridge.

You can, however, buy the chips online along with all the other parts you need to rebuild a toner cartridge, but the cost of the parts and shipping will be about the same as a rebuilt toner cartridge.
