HC10817 — Ambient temperature out of window at the drum module (THIB)
Agfa CT error code, reported by the Print Drum Module.
What HC10817 means
On DryStar 5500 (Type 5364/100) and DryStar 5503 (Type 5364/300) CT systems, status code HC10817 indicates: Ambient temperature out of window at the drum module (THIB). The code originates in the Drum Module — THIB Ambient Temperature Sensor section of the Print Drum Module. Severity level alarm (Alarm).
Reported action: Two documented causes: site temperature outside the printer's installation specification, or a malfunctioning ambient-temperature measurement circuit on the THIB. Confirm site temperature against the installation specification first; if it's within spec and the code persists, power off the printer and replace the THIB board..
Raised on the Drystar 5500/5503 when the ambient-temperature reading taken on the THIB (Thermal Head Interface Board), inside the drum module, falls outside the printer's allowed window. Classed as a Defect — the printer shows "Ambient temperature problem" and will not print until it's resolved. Its counterparts HC11227/HC11228 measure ambient temperature on the MEC board instead and are only Accidental-level.
