1. A sheet manufacturing apparatus comprising:
a pressing unit that includes a pressing roller that presses a material containing fibers and a binder, the binder having a function of bonding the fibers together, to form the material into a shape of a continuous sheet;
a separate sheet shaping unit that cuts the continuous sheet into a shape of a separate sheet;
a transportation unit including a pair of transportation rollers or an endless belt, the transportation unit being provided between the pressing roller and the separate sheet shaping unit and configured to transport the continuous sheet formed by the pressing unit to the separate sheet shaping unit; and
a cutter provided between the pressing roller and the transportation unit,
when transportation abnormality occurs on the continuous sheet that is being transported, the cutter cutting off a part, of the continuous sheet, located downstream of the pressing roller and upstream of a part where the transportation abnormality occurs, in a direction intersecting with a transportation direction of the continuous sheet, the transportation abnormality being a status that the continuous sheet goes off a transportation path that is defined at least by the pressing roller and the transportation unit.
