Solutions

Diagnóstico rápido

Error 50-05 is displayed when the lamp or image sensor fails its startup sequence. If the scanner head moves aggressively or stops abruptly, it confirms a hardware-level issue in the image unit.

Solución paso a paso

  1. Total Power-off: Unplug for 10 minutes to clear the firmware cache.
  2. External cleaning: Use a clean, dry cloth on the exposure glass.
  3. Inspection: Ensure no physical debris blocks the internal scanner head movement.
  4. Initialization: Power the unit back on and monitor if the startup calibration completes.

Prevención y mantenimiento

Avoid dust accumulation by using protective covers when the device is idle. Prevent exposure to extreme temperature changes that could cause internal condensation.

Cuándo llamar a un técnico

If the error persists after resetting, the image unit (lamp or motor) may have reached the end of its functional life and require a pro replacement.
