A paper jam has occurred around the duplex unit.

2. Check for jammed paper inside the machine. If jammed paper remains, remove it.

   

   Memo

   • If paper is invisible, check the innermost part of the printer.
   • If the paper removed from the printer is shredded or torn, remove all paper fragments from inside the unit so that none are left inside.
