PRINTER AND CLEANING METHOD OF PRINTER

摘要

PROBLEM TO BE SOLVED: To efficiently clean without the necessity of visual monitoring by a user. SOLUTION: The printer (100) has a head part (110), a control part (140), an optical sensor (120) and a cleaning part (130). The head part (110) where a plurality of nozzles are set discharges ink from each nozzle (112) to a medium (150). The control part (140) controls each nozzle (112) so that the ink is discharged from each nozzle (112) of the head part (110) to the medium. The optical sensor (120) detects whether or not the ink is discharged from each nozzle (112) to the medium (150). The cleaning part (130) cleans the nozzle (112) by sucking the ink from the nozzle (112) which is detected by the optical sensor (120) not to discharge the ink to the medium (150).
