How do I check for and remove paper jams in my Epson L120 that might be causing the 'Error Printing in Queue'?

Turn off and unplug the Epson L120. Open the printer cover and carefully remove any visible paper fragments. Check the paper path, including the rear access panel, for any stuck paper. Gently pull the paper in the direction of the normal paper path. Avoid tearing the paper. Once clear, close the covers and restart the printer.
