Embodiment Construction

[0026] Now, the present invention will be described in detail below with reference to the accompanying drawings showing preferred embodiments of the invention.

[0027] figure 1 The configuration of an image forming apparatus according to an embodiment of the present invention is schematically shown using a block diagram.

[0028] Such as figure 1 As shown, the image forming apparatus (denoted by reference numeral 1 ) includes a reader unit 2 , a controller 3 , a printer unit 4 , an operation unit 5 , an auxiliary storage unit 6 , a power supply unit 7 and a power switch 8 . Hereinafter, the units 2 to 6 and their elements are sometimes referred to as power supply objects.

[0029] The controller 3 controls the entire image forming apparatus 1 . The controller 3 has a LAN interface (LAN I / F) 208 communicable with the computer 9 via the LAN 10 . In other words, the image forming apparatus 1 is connected to a computer 9 serving as an external device via a network (LAN 10). ...

Abstract

The invention provides an image forming apparatus and a control method thereof. The image forming apparatus is capable of appropriately controlling power supplies to respective parts thereof when the apparatus is remotely started over a network. When receiving data from an external apparatus via the network, a controller of the image forming apparatus decides power supplied object, among a plurality of power supplied objects of the image forming apparatus, to which power supply is to be started at startup of the apparatus, and controls such that power supply to the decided power supplied object is started.

Description

technical field [0001] The present invention relates to an image forming apparatus capable of controlling power supply to various parts of the apparatus, a control method thereof, and a storage medium storing a program for executing the control method. Background technique [0002] Some recent image forming apparatuses have a network connection function. In many offices, this type of image forming apparatus (such as a printer) is communicable with a network to be able to send and receive information to and from an information processing apparatus (such as a personal computer) via the network and / or to other image forming apparatuses. Data processing is performed while sending and receiving data and commands from other image forming apparatuses. [0003] There is known an image forming apparatus that can be powered on by remote operation without requiring a user to go to the image forming apparatus to turn on the power. For example, Japanese Patent Laid-Open No. 2009-253748...
