Media Feed Probelm?

[thebump]

Thanks for reading. Have had our ValueJet 1604 a year now with no problems and running this all the time. Just this past week we are having print issues that look like media feed problems. The print is lighter at one end than the other. Or just bad prints in general, looks like maybe ink starvation. Is there some maintenance at a year old I should be doing that might be causing this? Nozzle checks and all test look great. Print starts out ok sometimes then it turns washed out for an inch or two. I seen this on our UV, but not on the Mutoh where there is not tension on both feed rollers. Any insight would help, pulling the hair out!

hi ,

check the dumper , i think is the problem of the quantity of ink

It looks like it could be a media problem. Have you tried a different media to see if the problem goes away?

Check the heaters. You may be drying too fast. Directional and Bi-directional printing can cause this also.

we tried different medias, changed the heat settings, replaced all the dampers, charged the ink system, rechecked bi-di alignments and PF, cleaned and cleaned, tried different profiles and resolutions from Onyx, chaged to different wave patterns...what am i missing??? we just keep getting light areas in the print and it seems to be either a feed issue or ink starvation but i can't think of anything else to try.

got it! we flipped the media feed encoder...why that helped, i don't know. the encoder is transparent so why does it matter? who cares, we're back up!

Check and make sure your pump lines are clear to waste bottle. Had a issue like that myself.
