Honeywell RL4 Plus II error E-005: Sensor fix

The Honeywell RL4 Plus II error E-005 indicates a media sensor malfunction, preventing the device from finding the start position of your labels. This error causes the printer to stop as it cannot synchronize the print head with the label edges. Knowing why does Honeywell RL4 Plus II show error E-005 is essential for keeping your mobile printing operations running smoothly.

Common causes

  • 1Dust blockage.
  • 2Incorrect media type.
  • 3Sensor misalignment.
  • 4Calibration error.

Solutions

Diagnostic

The printer cannot find the gap (the space between labels). If the printer feeds excessive blank labels or stops after every print, the sensor is likely blocked.

Troubleshooting Steps

  1. Open cover: Remove the label roll.
  2. Clean sensor: Blow out dust from the sensor slot using canned air.
  3. Check labels: Verify that your labels have visible gaps between them.
  4. Calibrate: Run media calibration through the printer settings menu.

Maintenance

Keep the sensor path clear. Use high-quality labels to avoid debris generation.

When to call a technician

If repeated calibration fails, the optical sensor may be failing and requires hardware replacement.

Frequently asked questions

The media sensor cannot distinguish between the label and the backing material.

Cleaning the sensor area and performing a media calibration usually works.

Yes, but make sure the sensor type matches your media (gap, mark, continuous).

Regular dusting of the sensor area during media swaps prevents failure.
