    Yellow ink will not print. C/M/K/Lc/Lm print on all nozzles. We have tried replacing the ink, changed the print head, running print head cleaning cycles. Printer shows no ink in cassette, but I have verified that it is new, liquid and unclogged. The level indicator on the bottom of the cassette is functioning.

    Any thoughts? I'm kinda desperate and pretty much out of money to throw at it. I do have some spare parts from another machine.

    Was this a new machine? Sounds like you invested into a money pit. I will give you a few grand towards a new printer for that thing. (So will all the dealers out there FYI)

    No, it was running and printing the day I bought it. Then when I moved it to my location, I didn't plug it in right away. Bad news, I know. I've never owned a wide format printer before, so this has been an account-draining experience for me. I think I have learned pretty much every lesson so far the hard way.

    I can afford a new machine if that "few grand" is all the new machine costs before the "few grand" discount...

    Yeah unfortunately that wouldn't be the case.

    Have you tried powering up the machine with the yellow ink cartridge uninstalled? Then installing cartridge when it asks for it. The other thing to look at would be the contacts inside the machine itself. Check for ink residue around that area.

    Tried both to no avail. Anyone know how to test the primer pump? Or anything else relevant that I haven't mentioned?
    It's sad how little information is out there on troubleshooting this machine.
    Or I'm just incapable of finding it :/

    I had a a similar issue with one of our HP 8000. Could be several issues going on. First when it goes through a cleaning cycle do you head and grinding or chattering noises that sound like gears are slipping? If so than the issue is going to be the bushing on the gear axle, it has worn down and the motor is not properly engaging with the pumps.

    If this is not the issue try placing a few drops of cleaner into the capping station and manually prime the pumps. You should see the cap cleaning solution drain down. If you don't see this than your capping station could be plugged up, tube could be damaged or disconnected.

    Also post an image of a head print test to see of you have any clogged heads.
