1638X Streaking?

Hey everyone,

Currently I'm having an issue with the 1638X leaving red streaks in the prints. At first it was doing that and also leaving super tiny red dots also. Since I read up something could be clogged, I printed a giant red rectangle, and that took care of the dots for the most part. The streaks remain. I've thoroughly cleaned it 3 times since, and keep doing nozzle checks but no fix. Everything but the one red section on one of the heads is 100%, with that one red one being maybe 95%. Hoping someone can point me in the right direction on what I should try next? Also, anywhere I can find a tech for south eastern Massachusetts while I'm at it incase I can't figure it out?

Thanks in advance.

 

Machine is 3 years old, I've owned it since new. Doesn't get a super ton of action as my main work is paint protection, tint and color change vinyl wrapping, with some print graphics on the side. It sits in my basement with 2 dehumidifiers running when it is humid. Not a ton of foot traffic, basement is finished, no carpet in site either. I've checked and checked to see if there was a fiber dragging any ink and I can't see anything. But its there nonetheless.

The pictures are attached. They are faint, but they are there. Almost looks like the first pass of the nozzle check deposits the ink, and something brushes it alongm but I see nothing. If you look at the image where you see the little white reflection, just above it you see a line, and it is consistent. Tried head 1 or head 2, same result. Makes no sense.

The only change is I had to upgrade to the newest addition of Flexi due to getting a new Summa and my last software not being compatiable with it. Is there a chance something might be messed up on that? Total shot in the dark since I have no idea myself.

 

Something has to be hitting. I raised the head to high, no issues. Back to medium, back to streaks. I'll be looking real close tomorrow at it.

 

Put the head on low, this was the result through the whole print.

 

Mutoh believes it's a voltage irregularity in the head. Solution is to replace the head.
