Publication number: 20170087821Abstract: A nozzle-clogging determining device is provided for detecting nozzle clogging without causing an increase in the cost. A nozzle-clogging determining device is configured to detect pass of droplets ejected from a plurality of nozzles of a head of an inkjet printer, and includes a droplet detector and a determination controller. The droplet detector includes a light emitter configured to emit detection light for detecting pass of droplets in a direction intersecting with a traveling direction of droplets, and a light receiver configured to receive the detection light. The determination controller consecutively ejects a plurality of droplets from each nozzle of the head at equal intervals, and has a threshold for performing determination on nozzle clogging on the basis of a light interception rate of the detection light which the light receiver receives when droplets are positioned inside a spot of the detection light which the light receiver receives.Type: ApplicationFiled: May 15, 2015Publication date: March 30, 2017Applicant: MIMAKI ENGINEERING CO., LTD.Inventors: KAZUMI SAKURAI, AKIHIKO MIZUSAKI, EIJI MIYASHITA, MASAKI KODAIRA, NAOKI TAKIZAWA
