Honeywell PC23d Plus Error: GAP not found - Fix Guide

The 'Gap not found' error means the Honeywell PC23d Plus printer cannot detect the physical gap between labels. This often occurs after loading new media or using non-standard label sizes. The most effective solution is to perform a sensor calibration to re-teach the printer the new media properties.

Common causes

  • 1Debris buildup: Paper dust blocks the infrared sensor.
  • 2Miscalibration: The firmware has lost the transparency baseline of the media.
  • 3Wrong mode: Driver settings mismatch (e.g., set to 'Black Mark' instead of 'Gap').
  • 4Hardware failure: Wear and tear on the optical sensor array.

Solutions

Diagnóstico rápido

The error usually presents with a blinking red light on the control panel. If the printer feeds continuous paper or ignores the stops between labels, the media sensor is likely obscured by debris or miscalibrated.

Solución paso a paso

  1. Check Loading: Verify the roll is correctly seated and the media guide matches the label width.
  2. Clean Sensor: Use 99% isopropyl alcohol to wipe the media sensor of any adhesive residue.
  3. Hard Reset: Power cycle the unit while holding the Feed button to initiate calibration mode.
  4. Run Calibration: Use the printer's touchscreen menu or PrintSet 5 software to perform 'Media Calibration'.

Prevención y mantenimiento

  • Monthly Cleaning: Clean the print head and media path whenever changing a roll.
  • Environment: Maintain the device in a low-dust area to keep sensors functioning accurately.
  • Label Quality: Use high-quality labels to prevent adhesive build-up on the sensor housing.

Cuándo llamar a un técnico

If the error persists after thorough cleaning and calibration, the media sensor hardware might have failed, requiring professional servicing or a mainboard diagnostic.

    Launch PrintSet 5 and trigger the media calibration command.

Frequently asked questions

It is a standard configuration error, not a permanent hardware failure, and can usually be fixed in minutes.

No, the printer stops to avoid wasting labels until the sensor is correctly calibrated.

Use premium-grade direct thermal labels compatible with the PC23d series to prevent residue issues.

Cleaning should be part of your routine whenever you load a new roll of labels.
