Finisher Troubleshooting Document



If a finisher is installed on the Lexmark C935 or X94x, the Paper Exit Sensor Flag has to be modified (i.e., shortened). If it is not modified, it will cause all media to feed into the finisher. It will produce paper jams when you attempt to print in duplex mode, as well.

Required tools

  • A pair of pliers (or similar tool)
