Hi You had the same issue with your VJ1304 as i do: one of the black channels has 70% of its nozzles that are stuck, i tried soaking the head in capping station with cleaning solvent, i even pulled out the printhead and tried to flush it slightly. Did it work like so (with a solvent resistant one)? Also: did you change the gasket from the water based printhead or did you reuse that one?Grtz,T.
