Like many using this printer I have microbanding. I did the cleaning cycles, even removed the print head and soaked it overnight. Replaced it, refilled the inks, and did 2 'acceptable' prints, 1 color 1 b&w, still had the banding, even printing with QuadToneRip 1440 super, unidirectional. Then went to do a head alignment. The head goes back and forth and on the final left the printer turns off. Does it every time now even after restarting the computer, deleting and reinstalling the driver. It says it's a commujnication error. I checked and replaced the USB plug. Pulled one cart out and put back in. It recognizes the inks during the setup. It won't even do a nozzle check, turns itself off. anyone recognize this glitch?
