Common causes
- 1LED exposure lamp end of life.
- 2Faulty electronic ballast feeding the lamp.
- 3White calibration table corruption.
- 4Severe dirt on the scanner glass preventing accurate reading.
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
