Fujitsu DL2401 paper-out-blink error: Solution Guide

The Fujitsu DL2401 error paper-out-blink signifies that the paper sensor does not detect the loaded form. This blinking alert often appears when the media is not properly aligned or there is a blockage in the path. To fix the paper-out-blink, you need to verify the correct positioning of the continuous or single-sheet paper. This dot-matrix workhorse requires proper input management to function correctly.

Solutions

Fast Diagnosis

The constant blinking of the 'Paper Out' light indicates the detection system is not receiving the signal needed to start. Check if the paper is inserted deep enough to activate the mechanical detection switch.

Step-by-Step Solution

  1. Inspect the path to ensure no old paper scraps are stuck.
  2. Align the paper against the printer's right guide.
  3. Press 'Load/Eject' to trigger the machine to capture the paper again.
  4. Clean the sensor with a soft brush if paper dust is visible.

Prevention and Maintenance

Avoid paper with adhesives near the sensor. Clean rollers with a damp cloth (isopropyl alcohol) to maintain consistent traction.

When to Call a Technician

If the blinking continues after cleaning, the issue may be the main logic board or the sensor's flex cable, requiring professional service.

Frequently asked questions

This happens when the optical sensor fails to detect paper or there is an obstruction in the feed path.

Yes, if the error continues, the printer cannot initiate any print jobs.

Use genuine Fujitsu ribbons for DL models, compatible with the 2401 series, to avoid printhead damage.

Clean the printhead periodically and keep rubber rollers free from ribbon debris or dust.
