Sheet conveyance apparatus and sheet conveyance method
In accordance with an embodiment, a sheet conveyance apparatus comprises a roller, an acceleration sensor, and a controller. The roller conveys a sheet. The acceleration sensor is attached to the roller to output a signal indicating a direction of gravitational acceleration applied to the roller at the time the roller rotates. The controller acquires cumulative angle at which the roller rotates based on the signal output by the acceleration sensor. The controller determines whether to replace the roller based on the cumulative angle acquired by the rotation angle acquisition section.
