Patent number: 9703249Abstract: When fixing is not necessary in a printing apparatus including a fixing unit, a sheet to be conveyed is allowed to avoid the fixing unit. Specifically, a fixing unit-bypass path is provided on a conveying path corresponding to the fixing unit. Further, when a surface treatment material is not applied to a sheet from a surface treatment material applying head, that is, when fixing processing is not performed by the fixing unit, a sheet is conveyed along a fixing unit-bypass path. Since a sheet is conveyed along an bypass path when fixing processing is not performed as described above, it is possible to prevent a sheet from being affected by heat or the like while the sheet passes through the fixing unit.Type: GrantFiled: February 5, 2016Date of Patent: July 11, 2017Assignee: Canon Kabushiki KaishaInventors: Kota Uchida, Kengo Nieda, Ryosuke Araki, Shinya Asano, Kanto Kurasawa, Mika Masuda, Yusuke Nakaya
