What is Agfa CT error code HC10912?

Thermal head heater not connected or malfunctioning. It is reported by the TH Module — Heater & Cooling Fan on DryStar 5500 (Type 5364/100) and DryStar 5503 (Type 5364/300) CT systems. Severity: Alarm; subsystem: TH Module — Heater & Cooling Fan.

What should a field engineer do about HC10912?

The appendix documents no dedicated Reason or Cure for this code — the only documented path forward is the printer's generic HC-code response procedure: Service menu, Test & Diagnose functions covering the thermal head and its interface board (THIB).. Isolate the TH Module — Heater & Cooling Fan 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).
