    Recently purchased a VJ1204. Pulled ink through the lines with syringes, but the ink seeps back up. I can remove the dampers and pull ink into them, but it does the same thing, goes back. Where else can I pull ink into? I try cleanings and nozzle checks and get absolutely nothing. I have purchased new dampers, cap top, cleaning solvent and wiper assembly. When I got it home, I followed the manual and installed ink cartridges, did a charge. Each color has two lines and where it splits into two lines there are black little caps. Could this be causing an issue.

    You have a leak somewhere.
    Please show pictures of the black caps?

    Check the needle what going into the cartridge. It can be clogged.

    I notice what sounds to be an air leak until I push this trigger down, then it stops. Is this normal?

    Is your maintenance station definitley working properly?
    The pump lines can get clogged especially at the double connector on the bottom which attaches to the cap top.
    Personally I would of replaced the complete maintenance station with a new one, especially if this machine has stood idle for a week or more.
    These machines need to be put into sleep mode if they are not used and NEVER turned off.
    You will find the more use these machines get, the less issues you have with them.

    I had this same issue a couple months ago, when installing new head in my vj 1204.
    If you pull hoses exiting maint. station insert a syringe in each line and do a easy draw
    with syringe, you should be able to pull ink. Do this with the pint head home.

    I can’t confirm if the maintenance station is working correctly or not. I see where the double connector is, but how do I disconnect the lines to try and pull ink through? I am not against replacing the whole maintenance station, just figured I would try and see if small repairs would fix it. I appreciate your help!!

    How do I pull the hoses out? I see where there are 4 lines that come together and are connected by white plastic piece and screws. Do I need to remove the white piece? Appreciate your help!

    What is the third hole on the bottom of cap top for? There is also a third line that isn’t hooked up to anything except the little black box on the right of the other picture. Looks to be a nozzle of some sort.

    That 3rd tube should connect to the 3rd whole in the cap top. If it's not connected, the maintenance station won't pull ink down and will instead pull air.
