2050 Air Detection Check
Use this SP to check air sensor detection. There is one air sensor at the top of each print
head sub tank (K1, K2, C, Y, M).

Pressing [EXECUTE] acquires the result of air detection by the air sensors and sends them
to SP2050-2.
• Results are displayed at SP2050-2 only if detection succeeds.
• Before you execute this SP, open SP2050-2 and record the display so you can
compare the values before and after execution of SP2050-1.
