Benefits of technology
Enables quicker activation of the image forming apparatus by determining if a restart is required, thus minimizing the time needed to return to a functional state after power switch-off.
Problems solved by technology
Recent image forming apparatuses and image processing apparatuses suffer from a problem that it takes a long time before becoming capable of being actually operated after having a power switch thereof operated by a user since the apparatuses have come to be equipped with multiple functions.
If the suspend mode is used for an off operation of the power switch, when the image forming apparatus cannot perform a normal operation suddenly due to a memory leak, an invalid operation process, or the like, the off operation of the power switch cannot cause the image forming apparatus to go through restart processing, which makes it impossible for the image forming apparatus to return from the normal operation disabled state.
However, in the case where the image forming apparatus is configured to restart the OS after executing shutdown thereof, when the power switch is turned off, the shutdown operation and the restart operation take place whenever the power switch is turned off, which causes a problem of increasing time required to shift to the suspend mode.

Embodiment Construction
[0030]The present invention will now be described in detail below with reference to the accompanying drawings showing embodiments thereof.
[0031]FIG. 1 is a schematic block diagram of an image forming apparatus (hereinafter referred to as the “MFP (multifunction peripheral)”) 100 according to an embodiment of the present invention.
[0032]The MFP 100 is equipped with multiple functions, such as a copy function, a printer function, a scanner function, and so forth.
[0033]Referring to FIG. 1, an MFP controller 12 controls the overall operation of the MFP 100. A printer section 13 performs image processing e.g. by electrophotography. A scanner section 11 optically reads an image from an original, and converts the read image to a digital image.
[0034]A power supply section 10 supplies power to each controller. A console section 15 operates the MFP 100. A power switch section 14 can be used by a user for power on / off operation, and controls the power supply state of the MFP 100.

An image forming apparatus capable of shifting to a state where quick activation thereof can be performed in a shorter time period when a power switch is turned off. When the off operation of the power switch is detected, a first state is stored, and when the on operation of the power switch is detected next, the state of the image forming apparatus is shifted to a second state from which the image forming apparatus can return to the first state. When the state of the image forming apparatus is shifted to the second state, time starts to be measured. When the on operation of the power switch is detected in the second state, the value of the measured time is acquired. The image forming apparatus is caused to return to the stored first state depending on the value of the measured time.
Description
BACKGROUND OF THE INVENTION[0001]Field of the Invention[0002]The present invention relates to an image forming apparatus, a method of controlling the image forming apparatus, and a storage medium, and more particularly to an image forming apparatus that shifts to a state where quick activation of the apparatus is possible when a power switch is turned off, a method of controlling the image forming apparatus, and a storage medium.[0003]Description of the Related Art[0004]Recent image forming apparatuses and image processing apparatuses suffer from a problem that it takes a long time before becoming capable of being actually operated after having a power switch thereof operated by a user since the apparatuses have come to be equipped with multiple functions.[0005]To solve this problem, there has been proposed an image forming apparatus having a function called “suspend” (suspend mode) which, when the user turns off the power switch, suspends operations of programs and the like being e...
