Need Help Help! We have a Mutoh Value Jet VJ-1324

[Priced Right Signs]

Not understanding why I am getting this streaking or banding.(not sure exactly what to call it) I keep it clean and performed nozzle checks and those are good. But anything solid black will come out like this lately, all other colors come out fine. Does anyone have any ideas on how to fix it?

Specific media profiles can cause it.
Bad roll of media can cause it.
K head going south can cause it.

I would try a different roll of media and see what happens.

Are those lines in the feed direction or the print direction? if they are the feed, check the rollers. clean with alcohol only, not cleaning fluid.
