VP540 sudden deflections on cyan head

[backwoodsgirl]

Can anyone tell me whats happening here? My cyan head did this after the holiday weekend (no printing for 3 days). It's never happened before. There was definitely not a head strike yet the test print is filled with deflections.
I've done a..... normal cleaning.... medium cleaning... manual cleaning.... soaked head in cleaning solution for 2 hours, anything else I should be doing? Other than panicking
Edit: Machine is a VP540

The most common and easiest fix is the captop. If it is not keeping the head sealed the head can dry and then the pump loses suction.

How old are the captops?
Are they Roland OEM or cheapies? (is the hose black?)

If I recall, I replaced the captops a year ago.... it makes sense... but I still need to get that head cleared up. I've got a bunch of them on hand, they have clear tubes.

clear tube captops for a VP are junk. Order one from Roland and put it on the cyan head.

Ok. What exactly makes them junk? And how do I get this head cleared up afterward?

Update.....
I've replaced the captop, pulled ink through with syringe, let the head soak overnight a few times, done multiple cleanings including manually pressing cleaning fluid onto the head gently, and the test print looks exactly the same. Anything else I can try?? This is just bizarre to me..I've never had so much trouble clearing up an imperfect head.

You have done all there is to do when trying to recover deflecting nozzles.......Try the soaking over the weekend, if no improvement on Monday, then the fix will be a new head. Would also replace the dampers at the same time.

Just my .02

Did you use the Roland captops?

You could try the limit position initialize and flushing adjustments to ensure the heads are lining up with the caps.

In case anyone is concerned while waiting on a new head I gave the current one a good ass whooping and got it 90% clear! I'm confident if I keep working on it I will get it nearly 100%. Lesson learned, use quality cap tops!!

Thank you for posting with a positive outcome.
Most that have a problem and ask for answers, never return to confirm what kind of solution they had.
