Do you have a wifi router connected to your printer??? If so, the router could be corrupted. Mine was hooked up to my desktop and wifi router. For the past week, the LCD screen on my printer kept showing a paper jam, but there was no paper jam. I talked to my Internet service provider and explained the problem. She told me it could be the wifi router that's messing up my connections. I took the router off the modem, printer, and desktop and my printer is functioning again. If that's your problem, it's way more cheaper to replace your wifi router than going out and buying a new printer...
