Solutions

Diagnóstico rápido

If you see black lines or the scan stops with the E004 light, check the glass underneath the cover. If there are scratches or grime, that is the source of the error.

Solución paso a paso

  1. Open the scanner cover.
  2. Carefully clean the exposure glass using a lint-free cloth.
  3. Disconnect the power and USB cable, wait 5 minutes, and reconnect.
  4. If the device attempts to start and fails again, confirm if the LED light under the glass turns on briefly.

Prevención y mantenimiento

Clean the scanner glass with a dry microfiber cloth weekly to prevent dust from interfering with optical sensors. Avoid abrasive glass cleaners.

Cuándo llamar a un técnico

If the error E004 persists after cleaning the glass, the LED lamp has reached its end-of-life and must be replaced professionally.
