Soooo I've been battling this issue the last 2 weeks. My Printer is leaving these lighter spots on my vinyl material BUT it prints banners FINE with the exception of a dark blue that I am trying to print where it spots in it as well.
I am also experiencing some pretty prominent banding as well.
Things I've troubleshot:
Ordered and Changed O Rings
Material contamination (I've rotated between two rolls plus the vinyl roll that printed fine but the other vinyl did the same thing)
Cleanings on cleanings (manual, normal, medium, & powerful have all happened)
Cleaning any thing that touches material
Any help is appreciated but I this is my last resort -- hoping someone else might have experienced this as well.
You will need to post a nozzle test
banding are nozzles, wrong profile, calibration related
spots that you are showing are called fisheyes - when oil or substance is on the surface of media and when ink hits it, it disperses the ink. You wipe your media down prior to printing.
I would agree with the idea that something was on my material if I hadn't already used up a whole bunch of it and that oil would've had to be distributed through my whole roll.
