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
- Check Loading: Verify the roll is correctly seated and the media guide matches the label width.
- Clean Sensor: Use 99% isopropyl alcohol to wipe the media sensor of any adhesive residue.
- Hard Reset: Power cycle the unit while holding the Feed button to initiate calibration mode.
- 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.

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.
