    Would anyone happen to know why overspray would occur? I am seeing red on the edges of a lot of prints. It's not very strong or visible but it's definitely there. Any idea what would cause this or how i can fix it? Thanks.

    A cleaning, or slow print speed down or head alignment

    usually the cleaning will clear that up, if the auto cleaning doesn't work try the manual. sometimes dust or fuzz can get on or around the print head area and cause that

    We clean it pretty frequently and that hasn't helped. How can i slow the print speed down and regarding the head alignment, is that something in the setting or something i physically have to do? I'm pretty sure it started when we got a tech in here to replace our black print head, related you think?

    In your other thread you said the printer was frozen for a few days. I would think that things will expand and contract enough to throw allignments out of wack. The tech should have done all the test prints and allignments even without replacing the head. IF he did not do all these tests, did he set the head rank number for the new head. If you can get into the service menu there should be a bunch of test prints for the allignment. Before he left he should have shown how it was printing to see if things were set up ok again.

    The printer seemed fine when we did the test prints and the overspray only happens randomly. We manually clean the printer at least once a week.

    Can You say anything more about printing conditions? Head speed, head height, humidity in the room, temepature etc.?

    When was the last time you changed the damper? If the damper is semi-clogged, it is restricting ink flow to the head and ink will spray out deflected rather than straight out.
