    Hi Everyone
    I have the 7900 woes.
    I bought one used and am not able to get past an error in the boot up phase.
    If anyone can shed some light on my problem I would appreciate it.
    Here's what happens:
    If I insert the ink cartridges in, up to 10, the machine will recognize them and accurately show their ink amount and the one empty bay saying:
    "No cartridge Install ink cartridge"
    As soon as I push that last one in, the printer does its little boot up procedure and them announces:
    "Ink cartridge error Replace ink cartridge" and flashes ALL compartments as empty with the red circle and white cross; not one cart is seen.
    It does not matter which cartridge is left as the last one to be inserted. They all register accurately until that last one is pushed in.
    I believe that the machine is satisfied they are all present and filled enough and moves on to its next boot up item and flashes this error.
    It is so fast but I imagine I can see the display showing the carts are ok before the "Ink cartridge error Replace ink cartridge" but it might take some slow motion photography to confirm this.
    Nevertheless I am stumped.
    The cost of parts alone is $1200 and for a tech to knock on the door $100, to come in and cough $175 per hour.
    If that gets resolved there is no guarantee the head will print.
    I am sure it is worth every penny but I have so few these days.
    So can anyone offer some insight into this mysterious behavior?
    Thanks in advance, Peter

    original carts, or not?

    if the carts are original, you may have a pressure leak in one of them, or in the pipes since the ink delivery in 9700 is pressurized. same goes with the non original plus there may be some faulty chips (not excluded with originals but very rare).
    one thing to try: press the ink valve on the cart with some pointy object, and with a small tube blow some air, gently cose you can spill to much ink, thru the nipple near by to eliminate bubbles.

    Epson 7900 ink error

    The carts are original and 8 are new and the remaining I "burped"
    It's something more insidious!
    Thanks
