Hello. I have an imagegraf ipf 700. I have run the head cleaning many times trying to solve. All colors will usually print fine after cleaning and maybe for one image afterwards, but then prints will be very dull u till I run the cleaner again. I have tried to ru. Nozzle adjustment, but I just get an " unable to adjust nozzle" message after I try it. Ink cartridges are full. I even took the printhead off and soaked it for a day to clean All the jets. Any ideas? Thank you
