• Code: SC282-11 ... SC282-15
• Description: Air Detection Frequency Error The amount of air allowed in the print head tank exceeded the threshold from the start of checking cycle. If the machine remains idle, small amounts of air will leak slowly into one or more of the sub tanks. There are two thresholds: •X The first threshold sets the amount of leakage within a 10-day period. •X The second threshold sets the amount of leakage allowed greater than a 10-day period.
