Solutions

Diagnóstico rápido

If the panel displays C-D160 when scanning, check if the scanner glass is clean. Watch to see if the scanning light (usually an LED strip) turns on briefly at startup. If there is no light, it is a direct illumination failure.

Solución paso a paso

  1. Clean the exposure glass with a soft cloth and ammonia-free glass cleaner to eliminate obstructions.
  2. Update the scanner firmware via the control panel if the version is outdated.
  3. Power cycle the unit by unplugging it, allowing the lamp controller to reset.
  4. Check brightness settings in the scanner menu; extreme adjustments can cause calibration errors.

Prevención y mantenimiento

Keep the device away from direct sunlight, as it interferes with scanner calibration. Clean the glass weekly to prevent the system from overworking the light source. Keep the office environment free of excessive dust.

Cuándo llamar a un técnico

Replacing the LED lamp or its internal controller board is a precise task. If the error persists after cleaning and rebooting, the component has reached its end of life and requires professional replacement.
