Fixing Label Gap Sensing Error on Honeywell PB51
The 'Gap Sensing' error occurs when the Honeywell PB51 cannot distinguish between labels and the liner. This is typically due to a sensor needing recalibration or incorrect media configuration. Proper sensor maintenance ensures precise label tracking and prevents printing over the gaps.
Common causes
- 1Debris or paper dust obscuring the sensor.
- 2Mismatch between label type (e.g., black mark) and settings.
- 3Misaligned media roll leading to sensor bypass.
Solutions
Running Sensor Calibration
- Ensure the label roll is properly loaded.
- Power off the device.
- Hold the Feed and Power buttons to trigger the auto-calibration sequence.
- Wait for the printer to feed labels automatically.
Software Media Settings
- Access PrintSet utility.
- Navigate to the Media tab.
- Verify the sensor mode matches your label type (Gap vs. Continuous).
Steps to follow
- 1
Sensor Cleaning
Gently clean the optical path with an alcohol swab.
- 2
Media Loading
Ensure the media width guides are snug against the roll.
- 3
Calibrate
Initiate calibration mode via the hardware buttons.
Frequently asked questions
Skipping labels usually indicates that the printer failed to detect the gap, meaning the sensor needs re-calibration.
Inspect the sensor window for any visible residue. If dusty, a quick blow of compressed air usually resolves it.
Yes, PrintSet allows you to trigger calibration directly from your computer without using the printer buttons.
