Patent number: 9139014Abstract: Conveyance of a sheet in an inkjet recording apparatus may be stopped under various conditions. In one example, a control device of the inkjet recording apparatus may stop conveyance on the sheet depending on the image to be formed in one or more portions of the sheet. Alternatively or additionally, conveyance may be stopped based on an amount of ink ejected or to be ejected onto a sheet, or portion thereof. The conveyance stoppage control may be used in conjunction with a corrugate mechanism in some arrangements.Type: GrantFiled: March 29, 2013Date of Patent: September 22, 2015Assignee: Brother Kogyo Kabushiki KaishaInventors: Tsuyoshi Ito, Takashi Omura, Yuki Matsui
