I think I need to change the head on my VS540i and just wanted to bounce my logic off someone to confirm my thoughts please.
I've had a recurrent problem with the 'G' channel / right hand yellow channel dropping out partially and/or completely, problem has got progressively worse. Printer has been running OEM inks, parts and fluids all its life.
Initially, this had been resolved by a powerful clean, subsequently by flushing the relevant section of the head. After it occurred several times I changed the damper to no avail and have since swapped said damper with another damper in the head and the issue stays with channel 'G' and does not follow the damper. O rings at both ends of the damper were intact, moistened, don't seem to be causing the issue and can't see any cracks in the head manifold. Several other methods have also brought the channel back to life - pulling ink into the head/damper via the cap top tubes, flushing the head again, medium cleans, overnight soaking of the head and all have worked short term. Once the test print eventually comes out ok I am able to print a run and the ink doesn't drop at all during the run, whether it's 1m long or 20m long, however it all goes back to square one after a print run.
Cap top was replaced 3 months ago, a new suction pump + motor and both yellow OEM cartridges were fitted last week.
Issue to me doesn't seem to be electrical and I cannot see any air in the lines at all having inspected several times from the choke valve to the damper. All other channels are perfect on the test print and haven't been an issue during the process of fault finding.
Time for a new head?
Your time is much appreciated,
Danny.
