Howard, the LCD showed I was down to 2% on one ink and refused to print. I replaced that cartridge and still the printer refused to print. Now the LCD panel shows all cartridges as empty and naturally won't print. I'm trying again today, but If the problem continues I shall trash can the unit and get something else. BTW, Epson told me to remove all the cartridges and unplug the unit for 15 minutes and try again. Same result - no workee.
