Abstract
In accordance with an embodiment, a sheet processing apparatus, containing a controller that acquires a predetermined data associated with a physical quantity of one of a driving motor or a driven member driven by the motor based on a predetermined signal, compare the predetermined data with a threshold value, and determine whether to transmit a request for increasing a discharge interval of a sheet based on the comparative result.
Claims6
A sheet processing apparatus, comprising:
- a sheet processing section configured to carry out a post-processing on a sheet discharged from an image forming apparatus;
- a motor configured to drive a driven member of the sheet processing section;
- an encoder configured to convert a rotation of an axis of the motor to which rotational force of the motor is transmitted to a pulse;
- memory configured to store a threshold value;
- and
- a controller configured to
- acquire a rotational speed of the motor based on a counted number obtained by counting pulses converted by the encoder,
- compare the rotational speed with the threshold value, and
- transmit a request for increasing a discharge interval of the sheet discharged from the image forming apparatus to the image forming apparatus if the rotational speed is smaller than the threshold value.
