Paper jam in duplexer - Article 538

A message on the printer display (13.12 error) will indicate a paper jam in the duplex area. This is located at the back of the printer (HP printers). Remove the duplex option, hold both sides, slightly lift up and pull straight back. There should be a piece of paper stuck in the duplex option. Remove the paper and put the duplexer back in the printer. The printer should reset itself and start printing again.
