I’ve been happily pumping out dozens of prints a day on my 2880 for the past four weeks. Took two days off and resumed today. Started with a nozzle check and experienced a paper jam (plain white paper). Cleared it and discovered that a cartridge was empty. Filled the cartridge and tried to nozzle check again. Paper jammed again. Tried several more times, shutting down the printer each time. Also unplugged it and waited a few minutes before firing it up again. Same result.
Any suggestions before I haul it down to the Epson Service Center?
