HP Secretly Rendering Printer Cartridges Unusable?
Momoru writes "Looks like a woman is suing Hewlett Packard, claiming that their "smart chip" technology, besides giving information about ink usage, is also secretly programmed to not work after a certain certain date." From the article: "HP ink cartridges use a chip technology to sense when they are low on ink and advise the user to make a change. But the suit claims those chips also shut down the cartridges at a predetermined date regardless of whether they are empty." We've reported recently on printer companies making questionable business decisions.
Since the article didn't back this up with any technical evidence, it's hard to tell if it's true. However, HP could have piggybacked this onto the low ink indicator, but only have it work like this 20% of the time. This would make enough people think, "hey, it doesn't happen to me so it's probably not true". However, 20% could still be a large enough percentage to make some money off this scheme.
Since this seems to be the first major suit announced, it'll be interesting to see how it works under the new law. Will there be real limits on attorney's fees? Will it be tied up in Federal Court even longer than it would've been in State Court? Will customers see something other than a coupon to buy more ink?
Stay Tuned to find out!
Inkjet was always touted as the 'razor' for any company coming up in the ranks. The problem is ... much much much research $$ goes into finding pigments and dyes that are permanent and light fast... as well as fit the receiver requirements.
/pill thats been in a bottle for 4 years. Ink's not a drug (tho as expensive as cipro!) but it is used to print a photograph that will, if said photo should fade, be lambasted as a "cheap ass company" for producing a bad product (See http://www.wilhelm-research.com/ ... mind you I dont have a very high opinion of his work... but it's still a consumer 'start' ... he'll be re-inventing quite a bit of knowledge because he's refused help)

And companies want to recoup that cost as fast as possible.
I worked on some yellow dyes and can tell you it's a very difficult process. Very expensive- you might have 6 months of failures.. and the floor lab might be stained a million colours.
But when it's done (and your scale up engineers have done it right) you'll get the cost of your ink way down.... I seem to remember some were down around 30$/kg. Pretty cheap. But that was the 'cost' of making the ink, not including all the $$ into research.
And being a chemist I can tell you inks in suspension aren't good after sitting for awhile. Yes, it's in a dark cartridge, but I don't know many people that will tell you it's safe to take a drug
Anyways.... this shouldn't surprise anyone that works with inkjets. The high-volume people will never see the problem, only the low volume people. And those that know will probably do something like this instead http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&cat
Take your computer offline, reboot, set your BIOS date forwards four years, bring it back up in Windows and try printing again. If it comes up bitching, take the debugger to their printer drivers and sniff out any Win32 API calls to GetSystemDate(). Patch according to taste (hardwiring a return value of 1/1/2000 should make their carts happy that they haven't expired yet.)
I can't think of any legitimate reason for a printer driver to know the current date, so there doesn't appear to be an immediate reason why this wouldn't work.

This evil device has 4 ink cartridges (black, cyan, magenta, yellow) and it will refuse to print if one of the cartridges is deemed empty. Now I never really print any color printouts, and yet, I keep running out of colored ink. I cannot seem to be able to print black and white without replacing the color. It goes through some sort of cleaning process every so often, and I think it just wastes the ink or something. Anyways, it claims these cartridges are empty even when they aren't! They haven't even been used to print anything! HP aren't the only thieves in the business. Something must be done, and I am glad to see this suit.
Panasonic laser copiers/printers have a trick that after X number of copies/prints the machine indicates that a new cartridge will be needed soon.
If you keep ignoring it eventually the machine shuts down and asks for a new cartridge to be installed.
On the side of the cartridge is a small plastic cover with a couple of electrical connections nearby, underneath the cover is a pico-fuse (small fuse that looks like a resistor) when you insert a new cartridge the printer detects the fuse, resets the counter and then blows the fuse.
Replacing the fuse on one of these used cartridges will indeed give you a few more thousand uses.
