Patent number: 10350894Abstract: According to an embodiment of the present invention, a printing apparatus that satisfactorily sucks and recovers a printhead is provided. A printing apparatus that includes a transfer member, and the first and second printheads has the following arrangement. The apparatus includes the first and second suction units which suck a plurality of nozzles of the first and second printheads, a common negative-pressure generation unit which generates a negative-pressure for suction by these suction units, and a moving unit which moves these suction units from one end to the other end of each printhead. Then, the moving unit moves the first and second suction units so as to pass through concave gaps with respect to ink discharge surfaces of the first and second printheads corresponding to the first and second suction units at different timings.Type: GrantFiled: February 26, 2018Date of Patent: July 16, 2019Assignee: Canon Kabushiki KaishaInventors: Takashi Horiba, Hikaru Watanabe, Kanto Kurasawa
