1. An inkjet printer comprising:
a printing unit comprising a color ink nozzle to eject a color ink to a sheet and a clear ink nozzle to eject a colorless-transparent clear ink to the sheet, the clear ink causing bleeding with the color ink; a controller configured to control the printing unit and determine presence and absence of misfiring in the clear ink nozzle, wherein, in an ejection test of the clear ink nozzle, the controller
drives the printing unit to eject the clear ink and the color ink to the 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 the color ink nozzle at least partially overlap each other on the sheet, and thendetermines the 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. |
