IMAGE FORMING APPARATUS THAT PERFORMS USER AUTHENTICATION BY WIRELESS COMMUNICATION, METHOD OF CONTROLLING THE SAME, AND STORAGE MEDIUM

摘要

An image forming apparatus capable of returning from the power saving state and performing user authentication by one action of holding an authentication card over a card reader even when the apparatus is in the power saving state. The apparatus performs short-distance wireless communication with an external device. A controller performs control processing including at least authentication processing. When short-distance wireless communication with the device is started, a short-distance wireless communication section delivers a return-starting interrupt, to the controller, receives authentication data from the device to thereby store the authentication data during returning of the apparatus. The controller performs authentication processing based on the stored authentication data after returning of the apparatus from the power saving state, and notifies the device of an authentication processing result by a different channel.

主权项

1. An image forming apparatus that performs wireless communication with an external device, comprising:
a control unit configured to perform control processing including at least authentication processing; and a communication unit configured to, when wireless communication with an external device is started, deliver an interrupt signal for returning the image forming apparatus from a power saving state to said control unit, and receive authentication data from the external device to thereby store the received authentication data in the course of returning of the image forming apparatus from the power saving state, wherein said control unit performs the authentication processing based on the stored authentication data after the image forming apparatus has returned from the power saving state, and notifies the external device of a result of the authentication processing by a method different from the wireless communication.
