Need Help Mutoh Valujet 1305 banding in black


New Member
I have a Mutoh Valujet 1305 that has run well for years. Now I am getting bad banding in the black. Nozzle check is terrible. If I print a solid black block, the banding isn't there for the 1st centimeter or so, then gets progressively worse. I have soaked the head and cleaned several times. I have run the head wash. I replaced both black dampers. If anything the nozzle check is getting worse, the more I work with it. Other than the pain of replacing the head, is there something else you suggest checking or doing that I am missing?
Thanks in advance!
