Today sent job to print, most greens, and suddenly it stopped printing. There is 50% of green ink left, after i try maintance cleaning, and test print, all other colors show up fine in test, but not a line on both heads for green color. What could be wrong with it?
did it go out gradually or suddenly from one job to the next? if the latter then it could be a bad data ribbon that goes to the head. i believe there are two ribbons one for each head. if you swap them you can confirm if it is the ribbon as the color drop will move to another color.
We had this happen to our GS6000. The tech after swapping out almost every part found out it was a bad ribbon cable.
Here how it went out, i start printing some green labels, its started ok but only about 10 passes green gradually went out. I am small home studio printer, so i really can't afford for those tech guys to show up and wonder about this situation, so i trying find a fix..Its always easier to just swam new heads etc.
Prior to that i did run greens on and off/ did cycle cleanings etc..
problem was the RIPs were not configured to use the green inks properly so the ink dried and caused head failures. most of the RIPS back then were just cmyklclm.
a rip update was sent out to correct it. both colorburst and onyx had updates to correct this. EFI? not sure.
sasha - if it started printing green then suddenly completely dropped out it is probably a data issue. could be your data ribbon going to that head. it happened to us.
heads usually gradually go out. you will see banding lines in the print then eventually it will go out.
