    Is there any way to see check the seal at the ink carts?
    Could it be the new Mutoh Ink cartriges design?

    Thanks for your help!:U Rock:

    What was the last thing you worked on?
    Why do you think you are getting bubbles?
    Where do you see them?
    How long have to had this printer?
    First remove the damper from the head and pull some ink through it. Look for bubbles if you do then not see them move back one more part and so on...

    well then start pulling ink. start at the damper and work your way back. just FYI my C had a broken nut just after the cart station so look there. The brass nut like broke in 3 parts they will do that from stress they move a little when pumping.

    I'll do a little plumbing work but I think the issue relays on the new Mutoh cartridges \ design.

    Thanks!

    The concept is pretty straight forward, the needle on the machine punctures a rubber plug on the cartridge and allows ink to flow.

    Are you seeing something that points to this as an issue?

    Yeah, this new cartridges won't fit right on the printer, hence starves the heads.

    Can you give me more info?
    A description as to how it doesnt fit?

    Any info you can provide would be appreciated.

    Pictures, drawings, etc.

    If the cart does not fit properly, get with you dealer and exchange it.
    Make sure that they send it back to Mutoh for evaluation.

    Thanks!

    i still wish someone would explain to me that why they have two cartridge designs. old one (that has reported no problems) for the valuejet, and a new design for the falcons. i think someone from mutoh said the new cartridge was to combat rising costs, but why just save money on the falcon side????? something just don't add up with all of this

    mutoh knows of the problem
    but they want us to use up the bad cartages first
    i have spent about 2000 dollars thinking something was wrong with my printer
    when it was mutoh's cartage all along
    i replaced heads 2 times, maint staition, caping station all ink lines the cqartage holder
    mutoh wont own any of it
    worked with mutoh tech through it all
    so it will be a roland for me and anyone i can convence
    it simply doesnt matter how good the printer is when ya get that kind of crap for suport
    and they know its the fault
    seem like someone could have at least told us of the problem instead of letting us flush the money away
    simply thats pretty sorry way to treat you customers
    im talking with a lawer now thinking of a law suite over the cost and lost production
    this went on for more than 2 weeks and all along mutoh knew of the problem
    pretty dam sorry!!!!!
