This section explains how to discharge unnecessary air inside the damper from the air purge ports of the carriage.

Air purging discharges unnecessary ink and air mixed inside the print heads from the air purge ports of the carriage.

Wear gloves before working.

If the display panel is idle for 10 minutes or more, maintenance work will be canceled, and the panel will return to the home screen. If this occurs, the process will need to be performed again from the beginning.

Do not place any object on the platen as the carriage moves there.
