Lexmark MS71x ? Troubleshooting 203.01 Paper Jam Error

What you will see

The printer posts a 203.01 paper jam error. The error may be observed after printer has been asleep for hours, (such as first thing in the morning). Often, no jammed paper can be found in the paper path.

Suggested Remedy

A. Look for any media that may be jammed in the fuser area and remove it.

1Pull down the rear door.
2Firmly grasp the jammed paper on each side, and then gently pull it out.


Make sure all paper fragments are removed and then close the rear door.

B. Check the media that you are using and verify the following:

  • The media is in good condition and not damaged.
  • The media is stored per manufacturer’s recommendations.
  • The media is supported. See the printer's User's Guide about "Supported paper sizes, types, and weights."
  • The media meets all the recommendations in Lexmark’s cardstock and label guide.
  • The printer is operating in a supported environment.

If no jammed material is found and the media you are using meets the recommendations above, please contact Lexmark Technical Support for additional troubleshooting suggestions.

C. Check the consumable status.

End of life consumables such as fuser, transfer roll, and/or pick tires can cause some errors. Check the fuser's status using the printer's Control Panel or xref_HO3373_xref. Order a maintenance kit if the fuser is already near its 'end of life' state.

Audience: ‘Lexmark only’ below

Some MS71x fusers were built with a minor defect in the narrow media assembly. The defect can cause the narrow media sensor flag to stick in the down position and cause 203.01 paper jams.

Suspect range of MS71x printers with this defect:

    • Manufacturing date: March 26, 2014 – October 14, 2014
    • Printer serial number: 406347990HR00 – 406347990PV00
    • Fuser date code: 14085 – 14286

How to read fuser date code

StepActionClick Image to Enlarge
1Look for the Fuser date code label (sticker).

The Fuser date code is the 10th to 15th digits starting from the left of the alphanumeric code. See portion of the image boxed in red.


The 10th and 11th digits represents the year while the succeeding 3 digits represents the day of the year.

In this example:

  • Date code = 14287
  • 14 = 2014
  • 287 = 287th day of 2014 = Oct 14

Should the fuser fall in the suspected range, send a replacement fuser using the appropriate part numbers below.

MS71x Return Program Fuser part numbers:

  • 40X8503 – 110-120V (Type 11)
  • 40X8504 – 220-240V (Type 13)
  • 40X8505 – 100V (Type 15)

You can also guide the customer in booting the printer to Safe Mode. This will temporarily recover the device's basic printing function while waiting for the replacement parts to arrive. See "How to boot the printer to Safe Mode" in this document's Partners-level section.

Rework marking

Reworked fusers at the factory are marked with a white or silver dot above the left cover screw as shown by the image below.
