ok, one side of my print magenta head completely dropped out... i didnt realize it but the cartridge ran out of ink... i replaced ink, ran countless powerful cleans, sucked ink thru the cap top with a syringe many times. it appears the line going to the damper is full??? i even pulled off the damper off the head took the damper off the line and sucked ink to the end of the line with a syringe, put line back on damper and damper back on the head and tried to pull thru the cap top still nothing? any ideas what i could do?
