    So before i took over this mimaki I guess they have spray back issues and it clogged the Primer/Clear Head.

    Does any one have any advice on fixing this?

    I have a different Mimaki, so I'm not sure if these are options for you or not. Have you tried a nozzle wash? You can also do a soak on the head using the F-200/LF-200 washing fluid. I know primer and clear are stickier inks.

    In my experience, once a UV head has been cured shut, it's virtually impossible to open up. That being said, Global Garage does have a service to flush heads and I have heard of people having success. Globalgarage.com is the site I am pretty sure.

    Are you getting any spray at all out of that head ? You can do a Nozzle wash and let it sit for a while to soak - Maintenance , Station , Nozzle wash - fill the cap with F200 fluid and set soak time to max then see if it cleared anything - you may have to do it several times - You should look at the bottom of the head and clean it with a swab and fluid . Sometimes you can luck out and the soak will loosen it up to get it with the swab .
