US 8,543,028 B2 · Maintenance system, cleaning system, and image forming apparatus

Abstract

A maintenance system includes a maintenance device and a control device that controls the operation of the maintenance device. The control device is configured to activate the maintenance device automatically when a numerical value associated with the operation of a maintenance target device reaches a predetermined threshold value and to activate the maintenance device when it receives an instruction from a user. When the control device is instructed to activate the maintenance device by an instruction from the user, the control device changes the preset threshold value such that the operation interval of the maintenance device becomes smaller.
