Thank you for at least giving me a logical explanation! Exactly the same thing happened to me – I have an HP officejet d145 & an HP officejet d135. Sick of paying exhorbitant prices for HP cartridges I started to source recycled cartridges online & low and behold both printers have stopped working & display ’supply expired – replace cartridges’ messages. I have replaced the cartridges 3 times & now the print heads but still the same message. Looks like HP have found a way to force people to stick with HP original cartridges. Unbelievable in this day and age that any organisation thinks they can treat their customers with such contempt & keep them – I too will never buy from HP again.

Like everything, there is a way to get around the problem if you’re willing to look around a bit. Go to

and the find the solution I found in January 2008. Short version of all the posts there:

Ger around the expired battery issue by taking out the button batter for about an hour. Do this either by removing the battery, as explained in
http://www.land.netonecom.net/tlp/ref/letters/hpPrinters.php

Or simply putting a non-conductive material (the posts pretty much agree on a business card folded lengthwise) between the battery and the retaining clip.

Latter parts of the thread have folks not returning the battery or removing the card and *not* affecting printer operation.

Yes, I just found out that my Laserjet toner cartridges (4 color) all expired at the same time. Evidently the black is on a different “tracking” system. Cartridge World told me that HP puts a chip in the toner cartridges that count your number of pages. When you reach the limit, it cuts off. Cartridge World also stated that they have changed plenty of cartridges that were 1/2 full of toner! What a scam by HP. This should be illegal and a lawsuit should be brought on any company that would steal from its customers in this manner. Basically HP and other companies are telling US what we are going to pay per page for prints.

Did not notice the “battery not required” note, so when I broke the battery clip, I just taped the battery back in with very sticky cellophane tape. Seems to work fine.

Well well well … another facet of the mysteriously vanishing ink the the color cartridge. I just talked to an HP technician today who told me that they use some color ( “Cyan” which is blue) in the black and white printing process “for clarity” … Well here’s some more bulls**t for the consumer to digest. Obviously when the “cyan ” tank runs out, the rest of the color cartridge won’t print. So even if you don’t use color …. they’ve found a way to sneak some cyan into their print process to make sure you have to consume that color cartridge. Otherwise too obvious a scam. SHARE THIS ….

if you look carefully at some large fonts, you’l see a faint bluish shadow …. NOT a clarifying agent …. but a way to force you to use color anyway.

I dont have to buy these overpriced cartidges. I get refill ink from Japan and about 1/4 cost. If we could learn to get things cheaper elsewhere, then these companies could go under and we wouldnt be ripped off so much.

I have an HP 9110 OfficeJet and and am encountering the cartridge expired problem.

Since I am severely visually impaired I have been unable to locate the battery.

I would sincerely appreciate **explicit** instructions to help me locate it for removal.

Almost certainly the OfficeJet 9100 series printers have batteries.

I make this claim because even if the printer is unplugged from the wall for a day or two it keeps the date current.

It’s hard to imagine that any but the most expensive capacitor can supply sufficient charge to keep the clock ally for that long.

HP is EVIL. Right up there with Microsoft

Found a plastic keycard worked great betwen clip and battery.

HP business inkjet 1200 solution for expired cartridges. There is a 9 pin connector located under the ink cartridges. The cover can be removed by prying it off. It is held in by 4 fingers the lock it in place. Under the cover there is a plactic barrier that I cut the middle section out to get access to the connector. I unplugged the connector and removed the white wire and plugged the connector back in and my expired cartridges works just fine.

For those who wonder, HP 9100 All-in-One series (I mean 9110,9120 and 9130) do have a battery. It is located on the left-hand side of the machine. There is a panel that you can pull out to ad extra-memory sticks to the machine. If you remove this pannel, and the steel piece that protect the memory slots, on the bottom-left-hand side of the compartiment when you face the machine, you will find the battery. Just proceed as you would add more memory to your printer, and you will not miss the battery. In case of need, see your user manual. i am not sure however pulling-out this battery reset the expiration date things. It did work for me for the black cartridge but it did not work for the colour cartridges. My mistake, maybe.

Removed the battery on my HP officejet d145. Works fine now. Use this link to find the battery. http://www.land.netonecom.net/tlp/ref/letters/hpPrinters.php
The clip is pretty tight. The battery is slightly bigger than the ones used in watches. Now using the printer without the battery.
