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

  1. Open the printer and remove the label media.
  2. Clean the sensor using dry air or a lint-free cloth to remove paper dust.
  3. Realign the sensor by sliding it to the correct position based on your label type.
  4. 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.

Steps to follow

  1. 1

    Verify path

    Ensure media moves freely over the gap sensor.

  2. 2

    Clean sensor

    Clear the area around the optical sensor using compressed air.

  3. 3

    Run calibration

    Initiate calibration routine via the LCD screen.

  4. 4

    Adjust guides

    Set guides to leave 1mm clearance to prevent jams.

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.
