What is Agfa CT error code HC10904?

MDM lamp or light sensor failure — module down. It is reported by the MDM / Densitometer Module on DryStar 5500 (Type 5364/100) and DryStar 5503 (Type 5364/300) CT systems. Severity: Alarm; subsystem: MDM Module — Lamp / Light Sensor.

What should a field engineer do about HC10904?

The source gives no specific repair steps for this code. Check the MDM lamp's connection and the light sensor circuitry on the DSH board before replacing the lamp or the DSH board.. Isolate the MDM Module — Lamp / Light Sensor subsystem and follow the status-code troubleshooting in the service manual. FSELIB documents the full diagnosis and remedy for the DryStar 5500 (Type 5364/100) / DryStar 5503 (Type 5364/300).
