    Help!

    I finally managed to get my printer up and running (it use to have severe horizontal banding), but I purchased a new printhead... Issue fixed! The issue I am now having is it won't stay "unclogged". Every morning, I wake the machine up, run a print head cleaning, and it's clogged again. Its to the point where I remove the printhead, sit it in an alcohol bath, push air through the top ports and it works! Who wants to do that every morning though? Is there anything else I can do? Printhead cleaner kits are rare finds, and at the rate I am going Im going to need a new kit soon. Help!

    P.S. Its my YK printhead only.

    What ink are you using HP or aftermarket? Are these HP genuine heads or some chinese?
    And I hope you are not actually pushing air trough the top ports or you might have already broken the head. It only takes a small small amount of air at very low pressure.

    Daily clogging is weird...
    we could leave our 25500 turned off for 4 weeks, turn it on again and it would be ok.

    im thinking its not ur printhead...
    as you say it fixed with new printhead...
    nope...im sure it 'fixed' because new printhead had ink in it...
    pushing air into head can burst the filter inside it

    i think you have an ink supply issue to the head...
    like as if the lines are clogged or an 'o' ring has failed somewhere...

    Well that's unnecessary difficult. You can just prime from the service menu.

    Check the primer assembly. Its probably missing the rubber stoppers, not allowing the printheads to properly prime. Sometimes it just affects one head instead of all of them.

    Just replace if any are missing, should be about $100.
