We have a Xerox Phaser 8860 printer that constantly shows a paper jam error. The exact error is: "Paper Jam - Open Exit Cover to clear". During the past several days at work I seached the entire printer for paper or small pieces of paper but I can't find any. I took off the top and side plastic covers, searched in the drum and rollers areas and I lifted up all the levers inside, but there is no paper. I also sprayed out the printer with canned air to remove all the dust. Any help would be appreciated. The printer is out of warranty.
