I see a bit of laziness in K head but other than that it looks more like a vinyl issue. Is your print heater on?

Please post a nozzle test print.

Your K head is most likely on its way to meet its maker. Ready to kick the bucket and cease to be. It's going to be a non-head. This is almost a late head.

Hi Sawdust,

Mrtn is right that head is well on it's way out now. Give us a call on Monday and we will see if there is anything that can be done.

Hi all!
We had the same problem with Сyan nozzles on Roland fj600.
I'd like to know just one thing - is it not recovered process?
Reinstalling head - the one way to get quality?

Generally when the test print looks like this the head is too far gone to be repaired. A replacement is almost always necessary in order to restore acceptable print quality.

If the FJ-600 was on dye or pigment inks then the nozzle condition can usually restored by flushing and printing hard because the nozzle deflection is usually just clogging. With solvent machines there's also an active chemical component which deteriorates the head. The more the head sits unusable the more it generates issues because the internals harden up and all kinds of chemical process in ink and in combination with the head materials complete. I have customers with solvent machines working for 12+ years every day, all day with original heads and the heads are still in perfect condition, the nozzle test print looks like new.

Print, my friends, print hard.

I second Martins advice.

It's the same as a car. If you just leave it to sit you will encounter more problems than if you run it all day every day.
