The 13.A2.D2 error means that the paper is failing to get to the pre-feed sensor (PS102). Several things can cause this error. Here are a few troubleshooting tips to help isolate the problem and get it fixed with as little cost as possible.
Is the paper stop arrow lined up?
Remove the paper and paper tray. Verify the paper stop arrow is lined up with the mark on the bottom of the paper tray. If the paper stop is moved too far forward the paper will bind when the tray raises. Also, make sure the paper is properly loaded. Sometimes a few pieces of paper will bend up in the front of the tray causing the tray to not properly lift and feed paper.
