Abstract
A sheet manufacturing apparatus includes a transport portion that transports a web formed of a material containing fibers, a humidifier that humidifies the web with air mixed with water supplied from a tank, a heating roller that is positioned downstream of the humidifier and that forms a sheet from the web, a moisture meter that is positioned between the humidifier and the heating roller and that measures a moisture amount in the web, a thermometer that measures a temperature of the water in the tank, and a hygrometer that measures humidity. A method of controlling the sheet manufacturing apparatus includes controlling, as a first mode, drive of the humidifier, based on a measurement result by at least one of the thermometer and the hygrometer until when a leading end of the web reaches the moisture meter, and controlling, as a second mode, the drive of the humidifier, based on a measurement result by the moisture meter after execution of the first mode.
