Honeywell PX45 Error 3002: Paper and Sensor Fix
The 3002 error on the Honeywell PX45 relates to a label sensor failure. This occurs when the printer cannot detect the label gap, often due to improper loading, misaligned labels, or debris covering the sensor lens.
Common causes
- 1Sensor blocked by paper debris or torn labels.
- 2Lack of calibration after switching label sizes.
- 3Label material with poor contrast between gaps.
- 4Media guides over-tightened causing paper waves.
Solutions
Diagnóstico rápido
If the machine stops and displays '3002' during a print run, ensure the label guide is not too tight and the sensor is properly aligned with the label gap or black mark.Solución paso a paso
- Open the printer and remove the label media.
- Clean the sensor using dry air or a lint-free cloth to remove paper dust.
- Realign the sensor by sliding it to the correct position based on your label type.
- Calibrate the sensor via the 'Settings > Calibration' menu.
Prevención y mantenimiento
Clean optical sensors monthly using dry air to prevent fiber accumulation. Ensure labels are clean and free of adhesive overflow, which can block the light-based sensor.Cuándo llamar a un técnico
If the error persists after performing a factory calibration, there may be a hardware fault in the light sensor, requiring specialized technical assistance.Ficha técnica del equipo

Frequently asked questions
It is an operational error that stops printing; it is medium-priority and generally easy to fix.
Compressed air is preferred. If alcohol is used, apply a very small amount to avoid damaging the optics.
Avoid low-quality labels with bleeding adhesive that can stick to the optical sensor.
Calibrate whenever you change label media or types, or once a month in dusty environments.
