Method of controlling sheet manufacturing apparatus

A method of controlling a sheet manufacturing apparatus configured to manufacture a sheet from a material containing a fiber, the sheet manufacturing apparatus being provided with

• a defibrating portion that defibrates the material containing the fiber and generates a defibrated material,
• an accumulating portion that forms web by accumulating the defibrated material,
• a web transporting portion that includes a transporting belt to come into contact with one surface of the web and to transport the web, and
• a pressing portion that includes a pair of pressing rollers formed from a first roller and a second roller, and forms the sheet by pressing the web,
• the method of controlling a sheet manufacturing apparatus comprising:
• a first step of transporting the web with the transporting belt;
• a second step of peeling a tip end of the web off the transporting belt;
• a third step of bending the tip end of the web by rotating the first roller in a first direction;
• and
• a fourth step of folding the tip end of the web by rotating the first roller in a second direction being opposite to the first direction and passing the web between the pair of pressing rollers wherein the sheet manufacturing apparatus includes an air injecting portion that injects pressurized air, and in the second step, the tip end of the web is peeled off the transporting belt by injecting the pressurized air, and comes into contact with the first roller.
