Hello
this problem seems to be an ink problem .. which ink are you using ????
Could you send me a picture of your nozzle test ..If the nozzles are deviated you must first correct it since this cannot be fixed with calibration.

I am using mutoh in from sign warehouse where I bought the printer. I’ll send the patter tomorrow when I get back. Thank you!

If this is something that happened out of the blue, it looks like a damaged head to me. Have you had any head strikes recently? How old is the head?

machine is around 5.5 years old. the test pattern prints colors fine its just odd.

ty for the help

It's probably the head. You could try replacing the head cables to see if that helps at all but in my experience when it fires erratically like that, it's a damaged head. We usually see 3 to 5 years out of a typical head although I've seen them go as long as 13 years!

I have them in stock here in Denver. It's up to you if you want to install yourself. Most of my customers are. We offer free tech support over the phone as well.

Your machine is a little hard to work on due to the size. As long as you take your time, work with the machine unplugged and discharged, and make sure all the cable get plugged in nice and straight, there isn't much damage you can do. If you have worked on other electronics before this won't throw any major surprises at you.
