Banding/Over Spray

[Prism1]

54" printer. Print a test print about 12-16" across...looks good. But when I print a test 46"-50" across, we get banding. ALSO, it looks like "Overspray" on the "white" letters/area in the solid colors, AND around the edges of the print. Also...got a few Black ink drops on the print. ????? Printing on 2 mil white vinyl... Help....

Try Cleaning it manually, run a couple medium clean cycles, try it again.

Have done that...Uggghhhh. Push "Test Print", all bars are printing in the test. ALSO...last week, the black ran out, but I re-primed it, and it has printed a few things ok. Black damper is full...

Changed pump and suction cups, no change. WEIRD thing is the Crop Mark "Line" ( about 2 pts ) looks like a Spiderweb on the top and bottom of the print...

Any other suggestions...we have been down for 2 days and this is killin' me.

Change your inks................. Tri aren't good for the system and lay down a different spray at a different consistency then the machine specs call for, therefore hurting things and eventually messing up the interior working parts.

I have been printing with triangle for almost 2 years now...never had this problem before...

Clean encoder strip , wipers , scraper , head soak.

check your vacuum settings. try 100% not AUTO. supposedly this can also cause banding.

won't help the overspray though...

over spray is the first instance of printhead failure on epson dx4 heads.

Sorry. I have replaced many.

the mention of "spiderwebs" got me tothink it is static electricity ..that happens a lot when using sign paint ..i know ,i know its different ,,but static electricity "pulled" the paint from the brush ,creating "spiderwebs" also the droplets is the electricity "pulling" ink from the heads .......wipe with snuggles drier sheets
