Issue description

The printer displays either 31.46, 31.66, 655.84 error codes, or the 201.22 paper jam error. The error codes 31.46 or 31.66 (for MS/MXx1x) or 655.84 (for MS/MXx2x) are precursors to the 201.22 error code.

There errors are caused by the following:

  • The toner cartridge was not fully inserted before closing the printer door.
  • The toner port ratchet on the IU is in the wrong position.

Solution

  1. Open the front door and check if the cartridge button is stuck.

  2. Open the front access door and check if the cartridge plunger (MS/MX3/4/51x, MS/MX3/4/52x, MS/MX71x/81x) is broken or damaged.

    1. For MS/MX3/4/51x, MS/MX3/4/52x, remove the toner cartridge and the imaging unit, and check whether:

      1. The toner is building up on the imaging unit port due to the inner lid not opening. If so, vacuum any loose toner from the imaging unit and inside the printer.

      2. The port ratchet is in the correct or incorrect position. if in the incorrect position, carefully move the right side lever into the front position and proceed to step 4. Otherwise, skip to step 5.

    2. For MS/MX71x/81x, check if an irregular sound emanates from the device, and compare it to the thumping and grinding sound recordings below:

      If the sound coming from the printer matches any of the sound recordings, stop here and contact Lexmark Support. Otherwise, proceed to step 4.

  3. Reinstall the supplies and test the printer. It may take printing several pages to recover the print quality if starvation has started to occur.

  4. Remove and reinstall the cartridge. Push the toner cartridge body forward one last time to make sure that it is completely seated.
