If you saw some improvement after a head soak, I would recommend changing the captop and making sure the exit lines were clear of clogs.

how's the damper?

how would i tell? I am waiting for a kind person to send me a service manual so i would know how to remove the damper for inspection without damaging anything.

ok so far i have tried:

1 firmware update (no change)
2 overnight head soak (some improvement then back to square one after short print run)
3 checked ribbon cables (ok)

now considering new captop from digiprint supplies all thought current captop looks mint. any one used the generic captop insted of the roland one?

While changing the captop I would also change the dampers. I would recommend OEM parts.

im thinking of removing the damper and injecting cleaning fluid directly into the head with a syringe what do you guys think

are you running white and metallic ink set up? those inks thicken in your captop and drain lines much more then the lmlcCMYK inks do... you may need to replace your captop and clear your drain lines... mine will back up ink in the top of the cap top and reside on the head and the test prints look like hell...

not using whites or metallics. just cmyk-lc-lm i checked the drain lines they are clear also the captop in not flooded. Thanks for the suggestion
