Having issues with a cyan channel what do you think?

[Mrteajunkie]

Today I went through the normal Monday cleaning routine on the bn-20.

As always printed a nozzle check to find one of the cyan channels is blank.
panicked I performed about 20 cleans from standard to power clean and eventually got back to 100% nozzle check.

then Randomly I printed another check being paranoid and nothing again.
It’s coming and going so I don’t think it’s the head but I suspect a damper faulty maybe?

I have found a kit for 6m maintenance on digiprint supplies for €135 but it seems a little too cheap?
Considering 1 damper is around £70-90 each here.

Any advice at this point would be extremely grateful.

If its only a few lines that are dropping I wouldn;t worry too much as it will not affect the print (to any sort of noticeable difference). It could be old ink or, like you say, the dampner.

Monitor it over the next few weeks and if it gets worse then I would probably replace the damper depending on how old that ink is.

This weather is playing havoc with printers so don;t be suprised if it settles when the heat comes down a bit.

Its the whole channel for the cyan see pics. There’s a gap where there should be lots of cyan lines.

ink is genuine Roland ecosolmax ink under 2 months old from grafityp.
I do have a full set of the Maribu inks I bought last week as a trial but not fitted yet otherwise I would be blaming those lol.

one minute it’s fine then next it’s missing.
what I don’t want is the cyan being blocked drying the head and then being stuck having to replace a £1700 print head.

Give Sean Taylor a call at GB Inks he will probably be able to assist you more as you are right, get it sorted now or very expensive fix later
