    I was having a problem with some bad ink clogging my magenta/yellow head, finally got everything clean now i have this disasterous mess printing. Anyone ever see this?? any ideas what it could be from? bad head now?? I have done several powerful cleans, switched the ribbon cables, pulled fresh ink through with the syringe?? im at a loss.

    Check the dampers and cap tops, this could be a damper problem for sure.

    I can't see the pic very well though.

    I hate to be niave( if thats how its spelled) but what exactly is the job of the dampers?? store ink to supply to the head? just a guess and how could they fail to produce this mess?? just want to know for future troubleshooting... Thanks.
  4. Reseat the ribbon cables at the printhead and printcarriage board, also inspect the contacts (look for dirty or bent contacts).

    Are you getting pooling of ink in the capping station?

    If you had some clogging issues with the ink, are your drain lines clogged?

    Not sure about the sp 300 but if my drain lines were clogged the heads would not load with ink and I was getting a lot of pooling in the capping station. Could also cause ink to contaminate the other color in the print head. You just have two print heads and CMYK right??

    One of the functions of the damper is to filter ink preventing any particles from being trapped in a nozzle.
    The damper sits on top of the head in all wide format printer. The more ink that gets passed through the damper,
    the more likely the chance for a particle build up. As the particles build up in the damper,
    ink flow is restricted and drop out occurs.
