HC11228 — Ambient temperature too high, measured on the MEC board (image quality only)
Agfa CT error code, reported by the Print Drum Module.
What HC11228 means
On DryStar 5500 (Type 5364/100) and DryStar 5503 (Type 5364/300) CT systems, status code HC11228 indicates: Ambient temperature too high, measured on the MEC board (image quality only). The code originates in the MEC Board — Ambient Temperature Sensor section of the Print Drum Module. Severity level alarm (Warning).
Reported action: If triggered by continuous printing in an already-warm room, wait for the temperature to come back down; otherwise the site's ambient temperature itself has to be brought down. No hardware fix is documented for this code..
Raised on the Drystar 5500/5503 when the ambient-temperature reading taken on the MEC board is too high. Classed as Accidental — the engine keeps printing, but image quality may decrease. Local display shows "Amb. temp. high". Distinct from HC10817, which measures ambient temperature on the THIB and does stop printing.
