Problem with overspray in high speed mode

[cfbeagle]

This just started on my SP540. I am using the profile GCVP: Glossy Calendered Vinyl ESM in Versaworks. When I run it in "High Speed" mode I get some "overspray" like streaks on the white areas following an area of heavy color.
Attached is a picture to illustrate.

Does anyone have any idea what is causing it? I don't think it is a file problem because it does it when I print both an EPS file and a TIF.

theres quite a few threads on overspray...maybe a search is in order?

Overspray might not be the right word... the edges are crisp. there are just streaks of black as if a nozzle is not shutting off or something.

ah I see it now...is your encoder strip dirty at all?

Move the carriage out and shine a flashlight from the other side of the carriage. You probably have some hair or string trailing from the printhead.

Looks like static issues. Media?

Encoder strip is clean and no debris dragging from the print head... Static raises an interesting question. Seems like static has been really bad in my shop lately. Any suggestions how to get rid of it?

For some reason manually cleaning the prinheads with a swab and some alcohol seems to help the static issues.
