HP Accused Of Expiring Ink Cartridges

from the must-use-by... dept

What is it with printer manufacturers and their increasingly sophisticated means of screwing over the customers who buy ink from them? Even going beyond various attempts at using technology to block out competition, printer makers have long been accused of having their printers claim a cartridge is empty when it's still 25% full. However, some consumers are claiming that HP goes a step further, and includes a "must use by" date encoded in the chip in their ink cartridges, meaning that if you don't use the ink by a certain date, no HP printer will let you use it any more. It's not clear if the complaint focuses on the fact that this exists at all, or (more reasonably) that the expiration date isn't given to consumers. HP's defense, of course, will most likely be to point out that older cartridges may clog up, causing damage to the printers. Which may, in fact, be true. However, without telling the buyer that the cartridge expires, they may have opened themselves up to trouble, as many people will assume the cartridges will remain good.

    Battery is problem with HP OfficeJet Pro L7650 and the expired cartridges problem

    I've got a L7650 and was having the problem with it complaining about expired cartridges and wouldn't let me print anything. I also have a CISS.

    I finally located the CR2032 3v button battery. It was a real pain to remove. I don't recommend trying unless you're hardware savvy. The battery is behind the PCBoard under the RHS lower cover (facing toward the inside of the machine). It is very hard to get at and there is the possibility of breaking your machine.

    This requires a Torx screwdriver set (like Allen keys but with a six pointed star shaped head).

    • Open the machine up so you can see the printer heads.

    • Then remove the power/network cables from the back.

    • Take the three screws out of the lower white case side (one top, two back).

    • Slide the side-case directly backwards and then it falls off to the side.

    • Then you have to unsocket all the cables and ribbons attached to the PCB.

    • Remove the screws holding the PCB down.

    • Carefully manoeuvre the PCB out (Valium might help). The battery is on the other side.

    • Pop the battery out of the socket and set it aside

    I've left my battery out and the printer seems to work fine without it.

    To reassemble you just have to reverse the dis-assembly. I found the PCBoard really difficult to get back into place. Be gentle and patient -- you don't want to damage the board. One of the ribbon cables had a tiny(3/4" x 3/32") hinged black clamp piece which fall off but is easy to replace (comb side towards socket, clicks on).
    Good Luck!
