Abstract
Official abstract text for this publication.
An image forming apparatus includes a main control unit including a plurality of control units, and a sub control unit configured to respond to a request from an information processing apparatus via a network in substitution for the main control unit when the main control unit is being operated in a power saving state, wherein, in a case where the sub control unit receives a request to which the sub control unit cannot perform proxy response from the information processing apparatus, the main control unit determines a number of the control units for responding to the request among the plurality of control units and returns from the power saving state to a normal state using the control units the number of which is determined.
First claim
Opening claim text (preview).
What is claimed is: 1. An image forming apparatus comprising: a multi-core CPU including a plurality of cores; a receiving unit configured to receive a packet transmitted by an external apparatus on a network; a shifting unit configured to shift a mode in which the image forming apparatus is operated from a first power mode, in which power is not supplied to the multi-core CPU, to a second power mode, in which power is supplied to the multi-core CPU, in a case where the packet…
