I was printing on my IIISi tonight and, between jobs, it switched from
working normally to displaying "50 SERVICE" (with the "50" flashing)
and not accepting print jobs.
Power cycling doesn't help.
I've done a little poking around, but haven't managed to find a service
manual for the silly thing. Bitsavers has only one file under
hp/printers/, and that one doesn't cover the IIISi. Google finds
another file which covers a few III printers, but not the IIISi.
Anyone have the manual, or at least have some idea what "50 SERVICE"
means I need to do?
(What is it with this week and hardware? I'm beginning to feel as
though any hardware I try to use this week breaks.)

I was printing on my IIISi tonight and, between jobs, it switched from

and not accepting print jobs.
I don;'t know the IIISi, but on all the HP (and Canon) laser printers
I've worked on, error 50 is a fuser problem. Either the fuser got too
hot, or more likely it didn't get hot enough.
Power cycling doesn't help.
There is a protection circuit in these machines (certainly the ones I've
worked on). If there's a fuser error, the machine will not work unless
it's been turned off for soemthing like 15 minutes (this is so if the
fuser has rteally got too hot, it's got time to cool down). There's a
capacitor on the DC controller board you can discharge to clear this
(very useful if you know the fuser is not too hot...), but I have no idea
if it's the same on the IIISi, or where that capacitor is.
Anyway, the most common cause of this is a problem with the fuser heater
itself. On the printers Iv'e worked on, this is a tungsten-halogen bulb
down the middle of one of the fuser rollers. If you extract the fuser
assmebly, it's generally fairly obvious where the lamp connections are,
and it's easy to test the lamp filament for continuity. Most of the time
when you get this error, the lamp is open-circuit, you need to replace it.
There's also a thermal swtich in series with the lamp inside the fuser.
This isthe final protection method, if things go badly wrong this will
cut the lamp power and prevent the thing seriosuly overheating. You can
test this too, it should show a dead short.
If all that's OK, then the proeblem is with the controller circuitry. I
could easily talk you through the CX and SX stuff, I've worked on them,
I've done component-level repair on them. But I suspect yours will be
different.
I've done a little poking around, but haven't
managed to find a service
manual for the silly thing. Bitsavers has only one file under
The servie manual will certainly be a boardswapper guide, but it might
show interconnections, etc.
Have you tried the Australian HP museum? There are some printer service
manuals there.

That's a fuser error. The fuser has gone open circuit (bulb burned out). Fortunately,
fusers for that machine are not expensive.
Anyone have the manual, or at least have some idea

Dont have a manual but I used to work on these years
ago. 50 service usually means either a bad fuser or AC
(high voltage) power supply module needs to be
replaced IIRC.

BTW, I remember someone like me wrote an article on repairguide about
that... http://www.repairfaq.org/samnew/printfaq/pcfsou1.htm has the text
a..
a.. Take off the AC module, where almost all the CX engine problems are
located :o) This is the aluminum "tower" besides the fuser assembly, and
where the AC cable comes in. Dismantle everything, change the little little
little heat accumulator (yep, it is so little that should be called "heat
accumulator") from the black TRIAC besides the mains power connector, and
put a good heatsink with heat paste there. Also, clean THOROUGHLY the upper
fan assembly, because when it fails, it can make things hotter. Hot enough
to melt the fuser gears. :o) Remember: ERROR 50 = TRIAC open. A TIC 226 fits
the bill on place. Of course there are other causes for error 50. But I've
never seen that in Brazil.

In addition to the causes mentioned, I have also had this error show up if
the unit is placed too close to an A/C unit or vent. This can also prevent
the fuser from coming up to temp properly.

I think I might have a copy on my fileserver somewhere... IIRC it came from
one of the P2P networks (probably edonkey / emule) and is about 20MB or so. It
certainly covers the LJ III, but I'm not sure if it covers the LJ IIIsi.
It might take a while to find, no doubt it's somewhere in /share/public with
the other uncategorised stuff...

Hi
Here is what the quick reference says:
The fuser is improperly seated
The connector J201 is improperly connected
- reseat the connector j201 on the sensor PCA
The SW 101 is disengaged
- Check the SW101 to make sure it is engaged with the top cover
closed
A temporary error has occurred
- Turn the printer off. Short the DC controller CP005 to bypass the
Error 50 time delay
You can turn the power off and wait 20 minutes instead of
shorting the cap.
It is basically an error that says the fuser isn't getting hot
within the specified time. It could be a bad fuser heater.

Back in June (2008), I wrote about my HP IIISi laser printer
complaining "50 SERVICE". Everyone agreed it was some sort of
fuser-related problem: heating element failed, driving circuit blown,
temperature sensor shot, something of that ilk.
Today I finally collected the round tuits to check it out - and yes,
the fuser "lamp" has failed open-circuit. Fortunately, a month or two
back I spoke with an printer repair tech who came to service a printer
at work; he gave me contact info for the place he gets replacements for
such things, so I'm set in that respect.
Just thought I'd report on the status.

Today I picked up a new fuser and replaced it, and now it works.

Is this something that can be fixed, or will I just have to put up with

Also, the thing is giving me a lot of paper jams with the page stuck in

Change the cart, or at least the photossensible cylinder of the toner
cart (of course, cheaper to change the entire cart hehehe)

Hi
It is the cartridge but not the photo sensitive drum.
This is almost 100% caused by the PCR ( primary charge roller ).
If the Photo drum fails, it is missing toner or fading text.
The PCR is deep inside the cartridge but can be replaced.
They normal go for around $10 someplace.
I'm told that one can clean them but I've not tried it.
It is a rubber like material and is suppose to carry the
charge off the photo drum.
There is also a scrapper that can fail. If it gets junk in
it, it will let toner get by and contaminate the PCR. It is
a self intensifying process. The more the PCR get contaminated,
the more gets by the scrapper. More that gets by, the more that
builds on the PCR, the less it is able to remove charge,
the more builds on the drum. There is normally a thin
flim of toner on the drum. This is normal.
One needs to learn how to open the cartridges.
I also have a 4SI ( used to have a 3SI ). These use the Canon
NX cartridge. After searching the net, I finally found these
pages showing how to open the cartridge:
http://sklepamm.super.sklep.pl/pdf/NXTechGuide.pdf
In picture 1 they show a special tool to remove the plastic
pin. I found a screw that just goes into it and a pair of pliers
works well( I forget the screw size ).
Also look at:

Remember, don't touch any of the surfaces with fingers.
The oil will mess things up.

New subject: ASCII Art
Some time ago, I was looking for the FORTRAN program or data deck used
to print the large Mona Lisa picture that I saw back in the '70s. I was
directed to Dave Gesswein's PDP-8 site, and a collection of vintage ASCII
art files:
http://www.pdp8online.com/ftp/ascii_art/
A 2-page wide version of the Mona Lisa was there, along with Buzz
Aldrin on the moon, Spock holding a model of the Enterprise and a huge
picture of the moon. These were all designed to be printed on a chain or
drum printer using overstrike to create pseudo grayscale values. I
printed off several images on a Data General LDM-800 line matrix printer,
and was happy with the results.
Several of the print files had the name "Sam Harbison" on them, from
Princeton in 1973. I managed to locate an email address for Sam, and sent
him a note asking about the process used in creating those pictures. With
his permission, I posted his response on my ASCII Art page:
http://sturgeon.css.psu.edu/~mloewen/Oldtech/ASCII/
He gives a very detailed explanation about the process. Photos of my
printouts are there, as well.

Is there some rubber roller in that portion of the paper path? If so, that's
probably the culprit there, too.
I just got into the yahoo "printer support" group, and am finding it useful.

There could be something sticky on the fuser roller. On these
printers, there is (or should be) a white felt pad stuck to a plastic
frame that sits atop the fuser roller and wipes it as it rotates.
Most people never bothered with that pad, to their detriment...you're
supposed to change it when you change the toner cartridge, and new
toner cartridges (usually) come with one. That pad is saturated with
fuser oil; it cleans and lubricates the fuser.

Thank you all for your great help!
[Dave McGuire, quoting me]
No; its physical extent is not as well-defined as a scratch is, and it
is (statistically) uniform under vertical translation, not repeating
with a well-defined period the way a scratch does.
However,
there's a vertical line of what I can perhaps best describe
as fog on every page. [...] Perhaps interestingly, this fog was
not present on the first few pages printed
So, the fog on the drum is a scratch,
or are you saying that there's a toner image of
the fog on the drum?
Yes. When I open the door over the roller, there are bands of fog
wrapped around the drum, in places that correspond to the fog on the
printouts.
Use a piece of tissue and (very!) carefully wipe at it
to see if it
comes off.
If it doesn't, then the drum is screwed,
It wipes off readily, and the stuff that wipes off looks like, well,
toner powder. But when I then put the cartridge back in and print a
test page, there is no recurring gap in the fog; apparently the
cleaned-off space didn't stay clean long enough to show on the page.
[dwight elvey]
There is also a [scraper] that can fail. If it gets
junk in it, it
will let toner get by and contaminate the PCR. It is a self
intensifying process.
That matches the symptoms. I'll try opening the toner cartridge and
cleaning off the PCR and the wiper blade - I could wreck it, I suppose,
but if my alternative is to get a new cartridge anyway... :)

back I spoke with an printer repair tech who came to service a printer
at work; he gave me contact info for the place he gets replacements for
such things, so I'm set in that respect.
Just publish if you find a good address. I saw this message on my
printer (4mx?) too, so I'm proably next ;-)

I was printing on my IIISi tonight and, between jobs,
it switched from
working normally to displaying "50 SERVICE" (with the "50" flashing)
and not accepting print jobs.
This is one of the most common problem in the II and III series. Usually
a broken fusor lamp or problem in the AC Module. In the II/III it is ALWAYS
the small thyristor in the AC module. You can use a TIC106 in its place.
Open the printer, fool the door sensor and measure 120 VAC (or would it be
VDC?) on the fuser's terminals. If you don't have the 120 V(d?)AC, the AC
module is broken, just change the main thyristor.
There should be a service manual on emule...

Power cycling doesn't help.
I've done a little poking around, but haven't managed to find a service
manual for the silly thing. Bitsavers has only one file under
hp/printers/, and that one doesn't cover the IIISi. Google finds
another file which covers a few III printers, but not the IIISi.
Anyone have the manual, or at least have some idea what "50 SERVICE"
means I need to do?
(What is it with this week and hardware? I'm beginning to feel as
though any hardware I try to use this week breaks.)

Check the fusor - bad connection or blown light bulb. If it does not
reach operating temperature this is the message you get...
