Patent number: 11964473Abstract: A printing apparatus includes an image formation unit, a tray on which a medium is placed, a movement unit, and a control unit. The image formation unit includes a first head forming a first image and a second head forming a second image. The movement unit is provided so as to be capable of moving the tray to a first position at which the medium is placed and a second position serving as a reference position. The control unit switches between a first mode and a second mode. In the first mode, a starting position is moved to an image forming region, and the tray is not moved to the second position, and a movement direction is changed to form the first image and the second image. In the second mode, after the first image is formed, the tray is moved to the second position, and then the movement direction is changed to form the second image.Type: GrantFiled: December 21, 2020Date of Patent: April 23, 2024Assignee: Seiko Epson CorporationInventor: Yohei Nunokawa

Patent number: 9527280Abstract: For a lenticular in which a lens body having low shape accuracy is disposed on one end portion, when the other end portion of the lenticular is detected, a position of a carriage at the time of detecting the end portion of the lenticular is stored in a buffer as a paper end position, a carriage motor is controlled such that the carriage is separated from a home position and moved in a main scanning direction, and a printing head is controlled such that an ink discharge having a color according to printing data is started at the paper end position. Since the lens body having high shape accuracy is disposed on the end portion of the lenticular, it is possible to land the ink onto a more suitable position with respect to the lens body, thereby allowing printing quality to be improved.Type: GrantFiled: May 28, 2014Date of Patent: December 27, 2016Assignee: Seiko Epson CorporationInventors: Manabu Kondo, Yasuhiko Yoshihisa, Takayuki Tanaka, Yohei Nunokawa

Patent number: 9481170Abstract: When printing is performed by discharging ink from a printing head onto a lenticular, a carriage motor is controlled such that a carriage is moved in a main scanning direction at a velocity which is slower than a movement velocity of the carriage at the time of performing a normal printing process with respect to a recording medium different from the lenticular as a recording paper and further separated from a home position, and the printing head is controlled such that an ink discharge having a color according to printing data is started with respect to an end portion of the lenticular, and thus the printing of one pass is started. Since the velocity is slower than the movement velocity of the carriage at the time of performing the normal printing process, it is possible to improve printing quality at the time of performing printing with respect to the lenticular.Type: GrantFiled: May 28, 2014Date of Patent: November 1, 2016Assignee: Seiko Epson CorporationInventors: Manabu Kondo, Yasuhiko Yoshihisa, Takayuki Tanaka, Yohei Nunokawa, Hitoshi Igarashi
