Solutions

Quick Diagnostics

The 31.01 code appears on the control panel immediately following a jam or feed failure. If your Lexmark printer shows error 31.01, the system has suspended operations to prevent internal component wear. Look for any debris inside the paper tray slot.

Step-by-Step Solution

  1. Power down: Turn off the printer using the power switch and unplug the power cord to ensure safety.
  2. Check paper tray: Remove the paper tray entirely and check for hidden scraps of paper in the feed path.
  3. Clean rollers: Inspect the feed rollers for debris or toner buildup that may hinder smooth rotation.
  4. Restart system: Close all covers, plug the printer back in, and power on to check if the error 31.01 is cleared.

Maintenance and Prevention

Ensure you use high-quality, dry paper to minimize dust accumulation inside the printer. Regularly wipe the rubber rollers with a clean, lint-free cloth dampened with distilled water. Using original toner cartridges is recommended to maintain optimal internal cleanliness and sensor accuracy.

When to Call a Technician

If the error persists after thorough cleaning or if you hear grinding sounds from the internal gears, it is likely that a sensor or motor component has failed and requires professional repair.
