Hello ARTBOT im writling from ireland i have a jv 33 running sublimation inks ,brand new pressurised cartridge bulk system .black was going out partially ,test draw showed blocks of black cells out after a meter or so ,next time possibly complete right side black completely out ,1 hard clean brought them straight back.then today we tested cartridges and released some air in cartridges at top with needle & tube (nit bulk system)
printed 20 meters black perfect then both black went completely.i cleaned ,fill up 3 times and even half hor nozzle wash and nothing.i switched yellow damper with black and cleaned ,then test draw printed yellow where black should be and nothing in yellow section where black was switched.to me this proves problem is from damper back can you help
