Title is my issue... I replaced the Magenta-Yellow print heads in my HP DesignJet z6810 on Tuesday, and it seems like since then, when I print anything from our normal Onyx RIP, no settings having been changed, the front 1" or so will be a lighter color than the rest of the print. In darker prints you can't see it very much, but in light colors it's like night and day.
It seems to do this on the 'leading edge' only, and my workaround has been setting Onyx to print 'Group Jobs Together,' and then let all the signs I need to print go in one 'batch' (i.e. turning the 'Print All Rows at a Time' setting on). And I will run a dark colored strip in front of the first print, so this issue messes up the bar, but doesn't encroach on my other prints. Aka if I queue up 12 signs it will only do this on the 'head' of the batch, but the other 11 behind it would be unaffected.
Any idea what's going on? These errors are not in my artwork. I am just thinking because it only started once I changed printheads that maybe the alignment is faulty or the heads aren't firing for the first few passes and need to be tossed/replaced.
