Common causes

  • 1Dust buildup on the sensor lens.
  • 2Adhesive residue on the scan glass.
  • 3LED light failure in the reading area.
  • 4Optical path obstruction by debris.

Solutions

Diagnóstico rápido

The error appears upon startup or when a document is inserted, meaning the scanner detects an obstruction preventing it from 'seeing' correctly through the glass.

Solución paso a paso

  1. Open the scanner lid.
  2. Gently clean the glass strips at the top and bottom.
  3. Use compressed air to clear any dust from the lateral sensors.
  4. Close the lid and run the software calibration tool.
  5. If the issue remains, check if the LED lamp glows clearly when starting.

Prevención y mantenimiento

Clean scanner glass monthly to avoid adhesive accumulation from old documents. Avoid touching optical surfaces with bare fingers.

Cuándo llamar a un técnico

If the error continues after professional glass cleaning and calibration, the internal optical sensor assembly needs to be replaced.

Frequently asked questions

Error E006 notifies that the optical detection sensor cannot properly perceive the paper surface.

Yes, in most cases, dust or paper remnants are tricking the sensor into registering a false obstruction.

Both the top and bottom scanning strips should be cleaned monthly.

If the error persists after a thorough cleaning, the optical assembly may have suffered an internal fault.
