Note: Slide the green latch (1) and pull the duplex cover up (2), as illustrated in the image above.


Remove the jammed media.

Note: Depending on the media's location, pull it either up or down. Since media can tear during a paper jam, be sure to remove all its fragments from the printer.

5 Check for any broken or loose parts on the duplex section. If damage exists, a service call will likely be required to resolve the issue.
6 Close the duplex cover. Close all doors and covers completely.
7 Power on the printer/MFP and try printing again. If the page prints, the printer is functioning correctly. If the issue returns, please contact Lexmark Technical Support or a local authorized service provider for additional assistance.

NOTE: If the error is something other than a duplex (230239) paper jam, use the location described in the error or the Show Areas feature on the printer/MFP operator panel to help you locate and clear the jam. Once the jammed paper is removed, touch the Continue, jam cleared on the printer/MFP's control panel and try printing again. If you cannot locate any jammed media anywhere inside the printer, a sensor unit may be failing. This will require a service action to correct. For information on arranging repair service, contact Lexmark Technical Support or a local authorized service center in your area.
