Honeywell PX940 RFID Industrial error E-101: Fix guide

The Honeywell PX940 RFID Industrial error E-101 is an indicator that the printer is failing to detect label positioning. This typically involves issues with the sensor reading the label gaps. Why is my Honeywell PX940 displaying error E-101? Usually, it's caused by dirty sensors or incompatible media.

Common causes

  • 1Adhesive buildup on the sensor lens.
  • 2Label media is too transparent for the sensor.
  • 3Mechanical misalignment of the media guide.
  • 4Software configuration mismatch.

Solutions

Quick Diagnosis

If the printer reports E-101, it is almost certainly a media calibration issue. Check the sensor path to ensure it is not covered by backing paper or adhesive residue.

Step-by-step Solution

  1. Use compressed air or an alcohol swab to clean the media sensor path.
  2. Ensure the media guide is correctly set for the specific width of your label roll.
  3. Enter the printer menu and trigger a 'Media Calibration' cycle to reset the hardware parameters.
  4. Confirm that the 'Media Type' setting on the screen matches your current roll.

Prevention and Maintenance

Keep the sensor path pristine. Daily cleaning in dusty environments is recommended to maintain sensor accuracy and prevent E-101 errors.

When to Call a Technician

If the sensor fails to calibrate after cleaning, internal hardware damage is suspected and a technician visit is required.

Steps to follow

  1. 1

    Sensor cleaning

    Clean the media sensor using compressed air.

  2. 2

    Check media

    Ensure the label roll is properly aligned with the sensor path.

  3. 3

    Calibrate

    Run the media sensor calibration from the printer display.

Frequently asked questions

This error occurs when the sensor cannot identify the gaps between labels, causing a calibration fault.

Yes, printing stops until the sensor can reliably detect the label start position.

Use Honeywell certified thermal labels for best results with internal sensor detection.

Cleaning the sensor path during every roll change prevents long-term E-101 issues.
