But the printer power supply was standalone, not in a box but the board
mounted on a piece of metal bent at 90 degrees. I though of looking in the
inkjet because I'd noticed that printers often had higher voltages inside.
It was very easy to extract the switching supply.

This is now dated material since there many inkjet printers that have
external supplies, so you can grab one of suitable voltage and use it.
Indeed, with the switch to switching supplies, AC adapters become much
more useful in the past. You get a compact power supply with more current
capacity than most of the old ac adapters, and you can find a wide range
of voltages.

The reality is that the mundane is often the most useful things one can
find in the garbag. That iPod is a neat thing, but I didn't really need
it. That usb to microUSB cable I needed, so it outright saved me some
money. I tend to save AC adapters because they can be used for other
things, but also because you never know when you might bring home some
interesting piece of electronics that needs such and such a voltage.

That looks like a serial interface using 0-3.3V instead of. -12-12V. An attempt could be made to decode the data by interfacing that to a PC serial port with a MAX232 and trying some settings until some meaningful data shows up. If they used some proprietary encoding instead of ASCII we may be out of luck still a binary analysis could be done.

I also used the parallel port with a software with good results as a digital analyzer.

Yep. That's what I just found. HP C7250 AIO printer.

There are 4 pins on each cart. I'll arbitrarily number them 1-4 from
top to bottom.
1 +3.3v DC
2 Data cartridge --> printer
3 Data cartridge <-- printer
4 Ground

OK. Did a quick measure on the bad cartridge, and it goes 1.2 ohms 3 to 4,
so that ties in nicely with what you found with your checks, and the
symptoms that it caused my printer

I had to rewire the parallel interface (including adding an inverter
or two) to make it 'Centronics Compatable' for connecting to my
Transam Tuscan S100 Bus machine.

It only printed unidirectionally but the bi-directional version
wouldn't have sped it up very much since the carriage return action
was so swift it was more akin to its predecessor, a Teletype Model 33
ASR.

I think it eventually got replaced by an HP Deskjet 960C and I
eventually hauled it out of my basement 'shack' to sneak it onto the
back of an untaxed wagon that had been illegally parked across the
road for the past couple of months ( I thought that if we'd had to put
up with this eyesore which was seemingly being pointedly ignored by

some utility out of it

That was replaced by a much smaller dot matrix printer
that I only stopped using when I got the first inkjet printer
that produced a much better result and cost peanuts.

I gave up on inkjets long before they 'got cheap'. The plain fact is
I simply didn't do enough printing to stop the heads clogging up
between jobs. I'd have done much better using a good old fashioned
impact dot matrix or daisywheel printer and a small box of re-inkable
ribbons (cartridge or open spool). The price of the consumables for
all inkjet printers is hundreds of times greater than that of the
impact based technology which, imho, is a total disgrace.

You don't need to print anything to stop them blocking up.
If you leave it on the printer will clean itself as needed.
My Brother aio has been sitting there happy for four years now.
It doesn't use much power as all it is doing is keeping the network
alive so it can wake up and print when required.

The ink level goes down slowly but you are talking about years if you
don't print anything. And as it uses optical level sensors you can
refill or use Ł1.99 carts in it.

For a long time, my primary printer has been an HP Photosmart series
all-in-one. It's a 6 ink job, which makes it expensive to replace inks
if you use the genuine HP article. So, for several years, I have been
using cheapo eBay inks. They come from China originally, and the most
recent ones I have been using, have translucent cases so you can even
see how much ink is actually in them. They are high capacity cartridges,
and the chip on them says so correctly. I have never had a problem with
the printer failing to recognise them as a high capacity cartridge of
the correct colour, and the usage indicator seems to remain accurate.

So, a couple of weeks ago, I come down in the morning, and it's sitting
there saying "copy abandoned", and the exclamation mark LED is flashing.
Sure enough, one of the missus's documents is in the top that she's
obviously been trying to copy before going to work. So I try the cancel
button - nothing. Nor the on / off button. No buttons work, so I pop the
power, just expecting to get the usual lashing for not turning it off
properly. But no. As soon as it gets going, it tells me that "The
following ink cartridges appear to be missing... " That would be all
six of them, then ...

Nothing would recover it from this. I had a trawl around on the net, and
there was a number of mentions of a couple of caps that bulge on the
main board, so I dived in to check, and yes ! there was one of them. I
checked its ESR for sport, and it was out the window. I stuck a new one
in, expecting all to be well, but it was just the same :-(

A friend lent me a printer in the meantime, while I had a think about
this one. Another friend is a pro photographer, and he has one of these
HPs also, and I knew that he only used genuine inks, so I rang him and
asked if he happened to have any empties laying about. He did, as he
takes them back to Staples, who give you half off in exchange. He came
over today with a bag of them, so I started by taking all of my
cartridges out. As expected, it told me that all of the cartridges were
missing, so I put in an empty colour one and restarted it. This time, it
told me that only five were missing, and the one that I had just put in
was nearly empty and should be replaced soon.

One by one, I added 'empty' genuine cartridges, and each time, it read
the cartridge ok. I eventually got to a full house, and all was well. So
one by one, I put my cheapo cartridges back in, and all remained ok,
until the very last one, dark magenta, when back came the message that
all six cartridges were missing. I went and got another from my stock
and put it in, and all was still ok.

I have actually seen the same symptoms with a brand new Canon printer
except that it was the genuine black cartridge that took the entire lot
down. I established this by trial and error after the cartridge OK leds
all went out unexpectedly when I put the black one in. I got a new
genuine black cartridge to make sure I didn't invalidate the warrantee
but it was a faulty supplied with the printer OEM cartridge.

So I'm guessing that the comms to these cartridges are just a simple 2
wire bus, and each colour just has its own address to allow the
processor to read them individually. I'm also guessing that the faulty
dark magenta cartridge, must have a short on one of the bus lines so
that when the processor issues the addresses in sequence to read each
cartridge at boot up, none of them are able to reply so the machine
assumes that they are not present.

How easy it would have been for the printer to have just got chucked in
the bin, for what was ultimately a simple problem ...

Not just HP where this sort of issue can arise. The first trick is to
take all the cartridges out and then insert them individually.

one evening (100% wool, Berber carpet). At the last moment, I decided
that SWMBO might kill me if I spilt the ink, so I did the job in the
workshop. Part of the job called for pressurising the cartridge after
re-filling. I dtifully pumped air into the cartridge. No print. I
pumped a little more air in. No pump. I pumped a little more air in
and BANG. Ink went everywhere. It's been ten years and I am still
finding ink in places I never expected.

I hate ink jet printers.

That's a sad story Trevor. To be honest, I can buy Chinese cartridges
for this HP so cheap that it's not worth arsing about doing re-fills.

While you're on, don't suppose you've got a schematic for a Mackie

of the usual suspects. It has a permanent overload LED, although it
seems to be an indicational problem as otherwise, it works just fine.

Bingo. I measured near infinity on all the pin connections on a known
good cartridges. I'm not a big fan of COB (chip on board)
construction, but I don't think that was the problem. COB failures
usually cause opens, not shorts. So, my guess(tm) is either crappy
constuction (adjacent wire bonds shorted), or static damage.

Yep, although I double it's RS-232 type data (startbit-data-stopbit).

An attempt could be made to decode the data by interfacing that
to a PC serial port with a MAX232 and trying some settings until
some meaningful data shows up.

That's why I included the link to the bus pirate board:
<http://dangerousprototypes.com/docs/Bus_Pirate>
The system looks so simple, that I doubt that a protocol converter
would be needed to deal with converting the binary data to something
meaningful.

If they used some proprietary encoding instead of ASCII we may
be out of luck still a binary analysis could be done.

Yep. I doubt if it's ASCII. I suppose grabbing a pile of carts and
looking at the data might be useful. I'll leave that for someone else
to do, as I'm not a programmist and don't see a way to make money
doing it.

>I also used the parallel port with a software with good results as a digital analyzer.

I didn't get to capture a data burst, so I don't know the data rate.
Looking at the scope settings, it looks like around 100KHz but I'm
guessing. That could probably be done with a parallel port logic
analyzer. I have several logic analyzers that could be used to figure
it out. Unfortunately, they're all inoperative and need some repair
work. Maybe if I get inspired (later).

I would try to apply some current through the short, it might clear and get the chip working. I once fixed an IC input this way.

What solder? The chip is glued to a gold plated PCB (no tin) without
any other components. See lousy photo at:
<http://inkjet411.com/?page_id=35>
In my experience with tin whiskers (in GE MSTR radio cavities and tin
plated connectors), the whiskers are "blown" by even the smallest
voltage across them. In this case, all 4 pins have a fairly large
(3.3v) potential between adjacent pins at various times, which is more
than sufficient to blow any tin whisker. Maybe a broken piece of wire
left around the chip during wire bonding, could easily produce a
short.

I wonder how they do these? Emulation?

No, I couldn't either. Mackie nor Loud Technologies will not help, even

way or another, it needed to go back to its owner Friday. Strangely, it now
works correctly, and has done all day. I replaced the comparator I.C. that
drives the LED a few days ago, but as expected, it didn't cure the problem.
About the only other thing that I did was to give the board a good scrub
down with alcohol, as a lot of the joints had that sort of 'grey, dusty'
look to them when an item has been stored somewhere a bit damp. At the time,
that didn't have any effect on the fault either, but now I'm wondering if it
has all dried out, and some moisture under a surface mount component has
gone, and cleared up a leakage path across the print. I'll try it again in
the morning, and if it's still ok, I'll stick the amp back in its cab, and

Why didn't they just leave the fucking thing alone ? If it ain't broke don't fix it !

Really, I am getting to the point where I want to be a caveman and shit.

HOLY SHIT ! Lookie what I just found !

https://www.youtube.com/watch?v=VlRXQEA0yj0

This is from a local movie host show called Big Chuck and Hoolihan. Later Hoolihan the weatherman (he was on the local news) left and it was Big Chuck and Little John, who had been their sidekick and worked these stupid skits and shit in between the segments of the movie. they showed the shittiest movies ever. I mean zero stars in the TV guide. But people watched because they liked the hosts, and their stupid skits. This one was from before Hoolihan left which makes it quite old. Let's put it this way, there were no VCRs. Video recorders yees, but probably no VCRs. I mean even Cartovision.

They did other ones, like "When I'm Calling YOU" and had Little John (the guy in THIS skit) running around like crazy and when they went "Shoo-wop-de-dop" he like opened a door and then shut it real fast. They also did the Nirobi trio one, but that has since been declared politically incorrect.

But yup, that is now in my collection, probably never to be watched again. When we are all dead and gone and aliens come to see what's up, they will go through my collection and all these artists, assholes and whatnot shall be then, thus immortalised, although I am not so sure that all of them would appreciate the, in retrospect.

Posthumously actually, I am not suire if ant of them folks are still breathing. What a trip.

You need to use a hot air drier after giving a PCB a 'Washdown" with
IPA. It's not sufficient to rely on the stuff evaporating out of the
PCB board 'under its own steam' and making it 'look' like it has dried
up as I discovered when cleaning the carbon smoke damage from my
homebrewed portable sound mixing box which had caused the op-amp
perfect rectifier driven VU meters to show a -10dB reading after I
replaced the burnt out safety resistors in the phantom power feed cct
to the stage box (the result of trusting a coon DJ's shoddy equipment
not to have mains voltage on its supposedly earthed connections).

When I powered the mixer up after the IPA and toothbrush cleaning
exercise, the meters shot over to the end stops. I figured that maybe
I needed to dry it out more thoroughly with a hair drier. I was right!
Once properly dried out, the meters stopped showing any spurious
readings and all was well again.

Yes, agreed. However, it has only been on very rare occasions that I've ever
suffered such problems after a cleandown, and I guess doing this stuff day
in day out, you get complacent. In theory, the only thing that should make
IPA conductive, is water content, and the stuff I use is 99.7% electronics
grade, and kept in a sealed tin, so it shouldn't be conductive at all - wet
or dry. If the symptoms had changed after the cleandown, I might have
suspected that a drying out was required, but it was identical before and
after. Still, it's all working now and has gone back to its owner. One of
the little mysteries that this trade flings at us from time to time, I guess
....

Also, I have to view online PDFs in IE right now because Firefox
wants a plugin. I DO NOT WANT TO up my version of the Acrobat reader.

May I recommend PDF-Xchange viewer (free) instead.
http://www.tracker-software.com/product/pdf-xchange-viewer
The advantages over Acrobat are:
1. No built in Javascript engine which the virus writers just love.

2. Does not crash randomly like Acrobat reader.
3. Does not hang on exit like Acrobat reader.
4. Does not fail to release allocated memory like Acrobat reader.
5. Somewhat better screen rendering.
6. Options and controls actually work, unlike Acrobat.
7. Built in OCR to convert unsearchable scans.
8. etc...

PDF-Xchange has been my default PDF viewer for several years now, and very
good it is, too.

Going back to the shorted bus lines on the ink cartridge, I 'blew' the short
off with a bit of DC, and when measured again, it had indeed gone. So just
for sport, I hung the cartridge back into the printer.

"The following ink cartridges appear to be missing or damaged" - all six
of 'em again ! Oh well, it was worth a try

I put the replacement back in, and all was well again, at which point, I
lost all interest, and chucked the bad one in the workshop bin. I say I lost
all interest, but it is one with a translucent tank, and you can see that it
is nearly full of magenta ink. And it's a high capacity one as well. And
yes, I know that these Chinese copies only cost me about a quid apiece, but
still, as I see it laying on the top of the pile of workshop detritus in
that bin, I still baulk at all that precious ink going to waste ... :-\

I have a collection of blunt syringes that came with various refill
kits. You could impale the defective cartridge, suck out the ink, and
inject it into a different cartridge.
