Abstract
An image reproduction apparatus including a power control unit detecting whether an error has occurred in supplying power to the image reproduction apparatus; and a booting control unit selectively cold-booting the image reproduction apparatus based on the detection of whether the error with supplying the power has occurred.
Claims19
An image reproduction apparatus comprising:
- a power control unit which detects whether an error has occurred in supplying power to the image reproduction apparatus while the image reproduction apparatus is in a suspended mode and which is configured to set a flag to a predetermined value if the error is detected;
- and
- a booting control unit which selectively performs cold-booting of the image reproduction apparatus based on the set flag,
- wherein in response to receiving a power-on signal with respect to the image reproduction apparatus from an outside in the suspended mode, the booting control unit determines to perform the cold-booting of the image reproduction apparatus without trying to resume operations of the image reproduction apparatus if the flag has been set while in the suspended mode, by the power control unit, to the predetermined value indicating that the error has been detected in the suspended mode,
- wherein if the flag is not set to the predetermined value, the image reproduction apparatus tries to resume operations and boot an image when the power-on signal is received, and
- wherein the booting control unit aborts the resumption of operation and cold-boots the image reproduction apparatus if the booting control unit fails to receive the signal indicating that the image reproduction apparatus resumed the operations within a predetermined period of time.

An image reproduction apparatus comprising:
- a memory, which stores a boot image;
- a control processing unit, which, while the image reproduction apparatus is in a suspended mode, sets a flag to a predetermined value indicating that an error has been detected while the image reproduction apparatus is in the suspended mode and which loads the boot image if the image reproduction apparatus resumes operation from a suspended mode and if the flag is not set to the predetermined value;
- and
- a booting control unit which selectively cold-boots the image reproduction apparatus if the control processing unit fails to load the boot image,
- wherein, in response to receiving a power-on signal with respect to the image reproduction apparatus from an outside in the suspended mode, the booting control unit determines to perform the cold-booting of the image reproduction apparatus without trying to resume operations of the image reproduction apparatus if the control processing unit fails to load the boot image and if the flag is set to the predetermined value, and
- wherein if the image reproduction apparatus tries to resume operations from the suspended mode and the booting control unit fails to receive the signal indicating that the image reproduction apparatus resumed the operations within a predetermined period of time, the booting control unit aborts the resumption of operation and cold-boots the image reproduction apparatus.

An image reproduction apparatus comprising:
- a control processing unit which transmits a signal indicating that the image reproduction apparatus resumed operations from a suspended mode if the image reproduction apparatus resumed operations;
- and
- a booting control unit which cold-boots the image reproduction apparatus if the booting control unit fails to receive the signal indicating that the image reproduction apparatus resumed operations from the control processing unit within a predetermined period of time,
- wherein in response to receiving a power-on signal with respect to the image reproduction apparatus from an outside in the suspended mode, the booting control unit determines to perform the cold-booting of the image reproduction apparatus without trying to resume operations of the image reproduction apparatus if the booting control unit fails to receive from the control processing unit the signal indicating that the image reproduction apparatus resumed operations, within the predetermined period of time,
- wherein the image reproduction apparatus determines whether, while the image reproduction apparatus is in a suspended mode, a flag is set to a predetermined value indicating that an error was detected while the image reproduction apparatus is in the suspended mode,
- wherein, if the flag is set to the predetermined value, the image reproduction apparatus performs the cold-booting without trying to resume the operations when recovering from the suspended mode, and
- wherein, if the flag is not set to the predetermined value, the image reproduction apparatus tries to resume operations when the power-on signal is received, and if the booting control unit fails to receive the signal indicating that the image reproduction apparatus resumed the operations within a predetermined period of time, the booting control unit aborts the resumption of operation and cold-boots the image reproduction apparatus.

A method of booting an image reproduction apparatus, the method comprising:
- detecting whether an error has occurred in supplying power to the image reproduction apparatus while the image reproduction apparatus is in a suspended mode;
- while the image reproduction apparatus is in the suspended mode, setting a flag to a predetermined value if the error is detected;
- and
- selectively cold-booting the image reproduction apparatus based on the set flag,
- wherein in response to receiving a power-on signal with respect to the image reproduction apparatus from an outside in the suspended mode, performing the cold-booting of the image reproduction apparatus without trying to resume operations of the image reproduction apparatus if the flag has been set to the predetermined value indicating that the error has been detected in the suspended mode,
- wherein if the flag is not set to the predetermined value, when the power-on signal is received, the image reproduction apparatus tries to resume operations and boot a boot image, and
- wherein if the image reproduction apparatus tries to resume operations and the booting control unit fails to receive the signal indicating that the image reproduction apparatus resumed the operations within a predetermined period of time, the booting control unit aborts the resumption of operation and cold-boots the image reproduction apparatus.

A method of booting an image reproduction apparatus, the method comprising:
- setting a flag to a predetermined value while the image reproduction apparatus is in a suspended mode if an error is detected indicating an interruption in a power supply to a memory of the image reproduction apparatus while the image reproduction apparatus is in the suspended mode;
- if the image reproduction apparatus resumes operations from a suspended mode when the flag is not set to the predetermined value, loading a boot image;
- and
- if the booting control unit fails to receive the signal indicating that the image reproduction apparatus resumed the operations within a predetermined period of time, cold-booting the image reproduction apparatus,
- wherein in response to receiving a power-on signal with respect to the image reproduction apparatus from an outside which is in the suspended mode, determines to perform the cold-booting of the image reproduction apparatus without trying to resume operations of the image reproduction apparatus based on the flag being set to the predetermined value and based on whether the loading of the boot image fails.
