Patent number: 12090766Abstract: A print medium is conveyed in a first direction and a printing head prints an image on the print medium by using a printable region of the print head that extends in a second direction crossing the first direction. Storing units can feed multiple sorts of print media. Among the multiple sorts of the print media, the print medium to print a check pattern for checking a printing state of the printing head is selected as the print medium to be fed from the corresponding storing unit. The check pattern is printed on the print medium by using a portion of the printable region of the printing head corresponding to a size of the print medium fed from the storing unit.Type: GrantFiled: January 5, 2021Date of Patent: September 17, 2024Assignee: CANON KABUSHIKI KAISHAInventors: Norihiro Kawatoko, Masashi Hayashi, Junichi Nakagawa, Seiji Abe, Kentaro Muro, Eiji Komamiya
