Diagnostic Steps

The Lexmark MS410dn error 34 occurs when sensors in the paper tray detect a different paper length than what is selected in the printer menu. If the error occurs even with the correct size, the tray guides may be positioned incorrectly.

Troubleshooting Steps

  1. Open the tray and verify that the paper guides are securely locked against the stack.
  2. Check the printer's display panel under 'Paper Menu' to confirm the tray size matches the physical stock.
  3. Verify the print driver settings on your computer match the document size being sent.
  4. Re-insert the tray firmly to ensure it triggers the size detection switches.

Prevention and Maintenance

Do not overfill the paper tray, as this can force the guides to slip. Keep the tray area free of dust and debris that could potentially trick the size sensors. Use the correct size markers provided on the tray floor to assist in alignment.

When to Call a Technician

If the printer persists in reporting the wrong size despite manual settings and guide verification, the size detection switch/sensor inside the tray bay may be malfunctioning and requires professional attention.
