Roland XC-540 - I believe light cyan head maybe bad

[davinciimports]

I have had overspray and already changed the dampers which helped a little but I still have overspray.
I am printing slowly to compensate at the moment. No overspray when printing slowly.

Head height is down to lowest. (I have never raised it)

6 years running : 8 hours a day X 5 days a week (print & cut so only half time printing)

Over time only replaced: blades, sponges, pinch rollers, cut strip, and recently the dampers. No mechanical parts have ever been replaced other than the dampers.

I am guessing it is probably the light cyan head so I did a Fill Pattern Test as previous posts recommend. Here is my result, any thoughts?

Sorry to be a noob but is the nozzle test the same as a Print Test? Or is there a nozzle test under another menu?

black looks the worst - head soak in cleaning solution for a few hours - see if it clears up

I have never done a head soak before. I will look through the forms to find some instructions.

We had a similar problem with our XC540, appeared to be over spray, but turned out to be a bad encoder strip. Might need a good cleaning if it's never been replaced. Or even just replace it, they are not too expensive.

I had a tech come out and he changed the K and Lc heads. Now printing without overspray.

I did try cleaning the encoder strip but that didn't help (it was dirty though so it probably helped with something in the future)

I also changed the cap tops. That didn't stop the overspray in our prints but it did stop the overspray from hitting the metal square around the miss fire sponge.
The overspray in our prints finally ended after the installation of the new print heads.
