Roland VP540 Cyan ink not coming through
Having real trouble printing blues as the cyan head is only firing half of what it should be at best.
various test prints as per photo.
I have tried everything I know how to and now totally lost as what it could be.
Done so far:
> change both cyan dampers
> switched damper placings
> changed capping station
> switched around outlet pipes to pump.
After doing this originally and syringed ink through from capping to pump I got it up and running.
Printed a fair bit until yesterday when it went back to as it was, tried all I know again with no joy.
Could it be the pump even though I have switched the other pipes around?
Any suggestions greatly appreciated
