Solutions

Quick Diagnosis

Error 31.01 usually comes with a specific screen message indicating the jam location (why is my Lexmark MC3426adw showing error 31.01?). Listen for unusual gear noises before confirming that the issue is indeed a paper obstruction.

Step-by-Step Solution

  1. Power Off: Always turn off the printer before trying to remove anything to prevent short circuits.
  2. Input Tray: Remove the paper tray entirely and check for curled sheets blocking the sensor.
  3. Rear Access: Open the back door of the unit; 70% of jams occur near the fuser.
  4. Cleaning: Carefully pull out the paper, ensuring no small scraps remain inside.

Prevention and Maintenance

Use only standard high-quality paper and keep reams in a moisture-free environment. Cleaning the rollers every 5,000 pages prevents traction errors and maintains efficiency.
