Lexmark MS622de error 31.01: Paper Jam Solution

The Lexmark MS622de error 31.01 indicates a paper jam detected within the input tray area. This code triggers when the printer senses that a page failed to reach the registration sensor within the allotted window. Users often ask why does my printer show error 31.01, and the cause is frequently related to misalignment or improper paper loading. Keeping the rollers clean is key to preventing this issue in high-speed printing environments.

Solutions

Diagnóstico rápido

Error 31.01 points directly to the input path. If you can see the paper, remove it carefully. If not, small debris from previous jams might be blocking the sensor trigger located near the front of the feed rollers.

Solución paso a paso

  1. Slide out the input paper tray completely.
  2. Scan the internal path for any crumpled paper or scraps.
  3. Clean the pick-up rollers with a soft, lint-free cloth.
  4. Reload the paper stack making sure it fits snugly against the guides.

Prevención y mantenimiento

Fanning the paper stack before loading is essential to prevent multiple sheets from sticking together. Perform roller maintenance every 3 months. Genuine Lexmark paper guides ensure the best performance for heavy daily use.

Cuándo llamar a un técnico

If the tray is empty and clear, yet the error 31.01 persists, the internal paper registration sensor has likely failed and requires a part replacement.
