View Full Version : HP 932c won't print; shows empty cartridge

I have a half used color cartridge that shows empty on the front of the 932c printer. I refilled it (It was only half empty) and it still shows empty, not letting me print anything.
I tried another cartridge and it shows ok, but when I put the older cartridge back in it still shows empty.

How can I 'fool' the machine into accepting this cartridge, or better yet how do I turn off this inaccurate feature?

I'm running 2k.

HP printers can be finicky wrt refilled cartridges.
Just use the cartridge that works.

Apparently the chip in the cartridge doesn't really measure the amount of ink remaining.
What it is really displaying is the time remaining until the cartridge is out of date.
It has a built in end date and whether you use ink or not it will gradually reduce the seeming content as the day approaches and show empty on that day.
One solution is to fool the chip by setting the PC's date to a time before the end date on the cartridge.
The cartridge will then work.
Ignore the irrelevant display or use it as a guide showing how much TIME of use is still available before you need to set the PC's time back again.
If you bought a full cartridge and installed it the day after it expired it would show as "empty".

I understand the printer/computer can be fooled by resetting it by tapeing the 4 top outer contacts on each side of the cartridge (first one side and then the other), I tried that but it didn't work. Also by changing out the cartridge with 2 to 5 'other' cartridges that should dump the memory of the 'bad' cartridge. Problem is I don't have 2 to 5 other color cartridges to try that one.

Question is where is the memory for the cartridges stored? In ther printer ot the computer?
If it is the computer, where in the registry is it(assuming it would be there)?

I think it's in the cartridge.

If you don't even connect the printer to the PC, but just connect it to the mains power and run a test page it would still refuse to print if the cartridge is outside it's end date.
Except the cartridge wouldn't know what the date and time was unless it's connected to the PC!
So if it was connected and it knew the time was past and it disabled the cartridge, then you disconnected it and ran a test page it wouldn't work.

I'm sure the makers could specify a time as precisely as was their inclination.
They might have specified a certain number of days, hours & minutes from the moment of the completion of manufacture.
Like 365 days, 0 hours, 0 Minutes from....

Or specified 12.00 noon on a certain date.

The time would need to be precisely specified.
Pc's don't understand how to deal with uncertainty methinks.
It would probably be timed to the second.
Otherwise how does the cartridge know the moment to disable itself?

I looked in the owners manual (you know, that booklet that is rarely looked at because it only has very basic info in it) and it states that if the light still flashes when the cover is open it is not a low ink warning.
I did clean the contacts, both on the cartridge and on the printer with no luck.

I disconnected the printer cable, unplugged the power cord for a few minutes. Repowered the printer w/o the printer cable (PP connection) swapped the cartridge with the bad one and only the power light is lit!

I reconnected the printer cable with still only the pwr light lit and printed a test page ok...........
Now I have a opened cartridge that has to be sealed somehow.

WTF!

It is the DRM of the printer world rearing its ugly head to bite you.

Most printer companies are moving to methods of trying to prevent the consumer for having to pay their overinflated prices for cartidges. This is one of them. It shouldn't really be an ink level warning light.....it should say tamper warning.

I think when you print a test page, the fact that the printer data cable is connected is irrelevant.
It would be interesting to try printing a test page without the data cable connected.
I’m surprised that it printed a test page using an out of date cartridge.

Do a google search on ink jet cartridge expiring; seems i remember seeing in another forum recently where some enterprising young programmer wrote a script to " fool " HP & Epson printers into actually using the full cartridge & ignoring the expirey date.

WTF= What the F...

What does DRM mean?

This doesn't seem to be a 'out of date' issue since it is working fine with the same cartridge now. I guess something got corrupted, but I don't know what disconnecting the printer cable would have to do with it UNLESS it was a bad contact problem with one pin! Something TOTALLY different that what we have been talking about!

AHhh!

It's "what the:

Feck = effect [Scottish]
[feckless = inef-fec-tive, weak, helpless.]
Fic = making, doing, causing to be.
Facere [latin] = Do
Fact = deed, a doing.
F*ck = http://tinyurl.com/hx4x
[Quite a nice little family of "doing" words don't you think?]
The original URL wouldn't work because it used "THE" word in the address and this site automatically replaced it with a series of ****'s.
It get's rid-ic-ule-ous [with the emphasis on RID].
But if we get RID of words the lingo-age is the poorer.

I'd have difficulty knowing the meanings of these words if they are ommitted from the dictionaries.
Robert Burns said [about the 1880's] "some of the spinsters of this parish spin their thread so fine it is fit for neither weft nor woof."

The United Kingdom Department of Trade and Industry plans to classify inkjet printer cartridges as consumables rather than electrical waste.
This then bypasses controls under the European Union’s “Waste and Electronic Equipment Directive” which sets out the rules for disposal of electrical goods.
Inkjet printer manufacturers would therefore not need to encourage users to recycle cartridges and instead could dispose of them in landfill sites.
This tends to increase the usage of smart chips.
Companies that recycle have said it will be too expensive for them to refill cartridges protected by smart chips, making it economically unviable to offer cheap refills.

Thumbs down to the UK DTI.

Why is the URL listed the way it is (tinyurl) when that isn't the address?

BTW..........someone else suggested this deal to reset the cartridge/printer:

1. Remove the cartridge
2. With the cartridge removed, unplug the printer.
3. With the cartridge removed, plug the printer back in.
4. Re-install the cartridge.

Read about it here http://tinyurl.com/

It's a system for shortening URL's easily.

You may have noticedthat the real address of the link you quoted was longer the the tiny URL posted.
