Abstract
In an ejection test of a clear ink nozzle, a controller drives a printing unit to eject a clear ink and a color ink to a sheet such that a dot formed by the clear ink ejected from the clear ink nozzle and a dot formed by the color ink ejected from a color ink nozzle at least partially overlap each other on the sheet, and then determines presence and absence of misfiring in the clear ink nozzle based on a degree of spreading of the dot of the color ink on the sheet after the driving.
