HELP! Inks not getting to heads

[Signs Excetra]

I have a Mutoh Falcon Outdoor 48" did a nozzle check and I am not getting magenta, lt magenta or yellow and getting barely any of cyan lt cyan and black.Dampers are full, tried drawing ink directly through capping station with a syringe. Can't get any ink through. Any ideas, besides getting a new printer???

when you pull at the other side of the capping station, do you get resistance or does the syringe just pull air?

things to check.

pump tube disconnected?
clogged pump?
bad contact with head?

I don't feel any resistance at all, just seems to pull air.

check to make sure you pump is properly hooked up to the cap tubes. not sure exactly how your printer is laid out (one pump for all heads, etc?). or also make sure the inner pump tube isn't broken. do you see any ink on the gears of the pump?
