My Epson ET-2800 printer is giving me an E-01 printer error. It is telling me that there is a paper jam. I do not see any paper inside of the printer. It makes a loud click sound prior to giving the error. I have read that I should remove paper trays and clean the pick up roller. I have no idea how to remove paper trays on this model. Any help would be welcomed. I have contacted Epson Support, but no one has replied. Thank you,
