  • 1Sensor coated with adhesive residue.
  • 2Label path misaligned.
  • 3Incorrect sensor type selection.
  • 4Sensor component failure.

Solutions

Quick Diagnosis

Error 001 typically means the printer is "blind" to the labels. Check if adhesive from previous labels has coated the optical sensor.

Step-by-Step Solution

  1. Remove the label roll and ribbon.
  2. Gently wipe the optical sensors with an isopropyl alcohol swab.
  3. Reinstall media, ensuring it travels through the sensor bracket correctly.
  4. Perform a 'Media Calibration' from the printer UI.

Prevention and Maintenance

Establish a cleaning protocol after every media change. Use high-quality Honeywell consumables to prevent sensor buildup.

When to Call a Technician

If the calibration fails repeatedly after sensor cleaning, the sensor hardware may be faulty and need replacement.
