Abstract: Variation in the amount of material that is dispersed when material containing fiber is discharged by a sieve is suppressed. A fiber processing device has a drum that screens defibrated material containing fiber, a mesh belt that accumulates first screened material discharged from the drum, and a processor that processes the first screened material accumulated on the mesh belt. The drum operates at a first speed during processing by the processor; and when the drum starts from a stationary stop, a startup operation including a state in which the drum operates at a slower speed than the first speed executes for a specific time.
