Common causes

  • 1Adhesive buildup on the optical media sensor.
  • 2Misaligned paper guide preventing proper gap detection.
  • 3Incorrect media settings configured in the driver.
  • 4Hardware wear on the sensor LED emitter.

Solutions

Diagnóstico rápido

The E1 error is characterized by a blinking red LED and an interruption in printing. Confirm the error by checking if the media is positioned correctly within the sensor channel.

Solución paso a paso

  1. Power off the printer and unplug it.
  2. Clean the optical sensors using a soft, lint-free cloth or compressed air.
  3. Ensure the media guide is snug against the label roll.
  4. Perform a hard sensor reset by holding the FEED button while turning the power on.

Prevención y mantenimiento

Keep the internal housing free of label adhesive and dust. High-quality media reduces sensor wear and prevents sticky residue buildup.

Cuándo llamar a un técnico

If the error persists after calibration, the internal mainboard or optical sensor array may be failing and require professional servicing.
