    Does anyone here know how to replace/remove one? If so, do you have a video or paperwork that shows how?

    Thank you.

    LaserMan, what do you mean by the INK SENSOR?

    The sensor that tells you the ink is running low or empty.

    My yellow ink sensor (#8) keeps telling me my ink is at end, but i can kind of jiggle the cartridge a bit and it reads it fine. So, that tells me the sensor is either lose or wearing down??

    The issue is that the JV3 reads that there isn't a cartridge (yellow) in. It just started after a run. The ink is pretty full and the date is march of 2013. I've gotten it to read the cartridge, only if i "wiggle" the cartridge a few times.

    Any thoughts on how to fix this??

    From the service Manual, here are the possibe causes...

    Cannot read the IC.
    Problems Cannot read the IC.
    Causes
    1) The ID board contact of the ink cartridge is stained.
    2) The board on the ink cartridge side is damaged.
    3) Failures regarding the main unit board.
    Checking procedure 1) Visual check of the ink cartridge board contact.
    2) Replace the new ink cartridge.
    3) Change to the connector of the slot from which the IC can be read
    normally.
    < Make sure that the changed slot number is selected.>

    Remedies
    1) Wipe off dirt.
    2) Replace the ink cartridge with a new one. If the IC can be read normally,
    the board on the ink cartridge side is defective.
    3) If the IC can be read after changing the connector, replace a IO PCB or
    main PCB.
    If the IC cannot be read after changing the connector, replace a ID board
    or ID cable.

    There's a small toggle switch on the side of the cartridge bay assembly that reads the depth of the tab on the cartridge itself. Either you have a problem with that, firmware, or the chips on your carts.

    You can replace the entire cartridge assembly in one shot, as it's ordered as a single piece, but if you can get away with it, I'd just re-seat the toggle switch sensor, and see if that does the trick. Getting to the cartridge assemblies is pretty easy if it's on the left side of the machine. If it's on the control panel side though, you have a bit of careful disassembly to do.


    Edit:

    Also, what Bobby said. Posted before the thread updated with his post.

    Loose connection of the ID Board maybe?
