Abstract
An information processing apparatus to which an external device is attachable includes an initialization unit configured to, when the information processing apparatus is activated from a power-off state, execute initialization of the external device, and not to, when the information processing apparatus is returned from a power-saving state, execute the initialization of the external device.
Claims11
An image forming apparatus comprising:
- a storing device that stores store settings of a pre-set power state to which the image forming apparatus is to be shifted in a case where an operation to turn off a power switch is detected;
- a memory device that stores a set of instructions;
- and
- at least one processor that executes the instructions to:
- determine, if the image forming apparatus is returned from a suspended state, whether there has been a change of an optional device attached to the image forming apparatus, the change of the optional device being at least one of an installation of a new optional device on the image forming apparatus, a removal of an optional device from the image forming apparatus, an addition of a new optional device, and a replacement of an optional device;
- shift, in response to a detection of the operation to turn off the power switch, the power state of the image forming apparatus from a standby state to the power-off state even if the suspended state is set as the pre-set power state to which the image forming apparatus is to be shifted, in a case where it is determined that there has been the installation of the new optional device on the image forming apparatus, the removal of the optional device from the image forming apparatus, the addition of the new optional device, or the replacement of the optional device;
- and
- execute, in a case where the image forming apparatus is activated from the power-off state, acquisition of information about one or more optional devices attached to the image forming apparatus, the acquired information including at least one of a model name, configuration information, and operation speed of the one or more optional devices attached to the image forming apparatus;
- initialize, based on the acquired information about the one or more optional device, at least one of the processor and the one or more optional devices.
6 more elements
A method for controlling an image forming apparatus, the method comprising:
- storing settings of a pre-set power state to which the image forming apparatus is to be shifted in a case where an operation to turn off a power switch is detected;
- determining, if the image forming apparatus is returned from a suspended state, whether there has been a change of an optional device attached to the image forming apparatus, the change of the optional device being at least one of an installation of a new optional device on the image forming apparatus, a removal of an optional device from the image forming apparatus, an addition of a new optional device, and a replacement of an optional device;
- shifting, in response to a detection of the operation to turn off the power switch, the power state of the image forming apparatus from a standby state to the power-off state even if the suspended state is set as the pre-set power state to which the image forming apparatus is to be shifted, in a case where it is determined that there has been the installation of the new optional device on the image forming apparatus, the removal of the optional device from the image forming apparatus, the addition of the new optional device, or the replacement of the optional device;
- executing, in a case where the image forming apparatus is activated from the power-off state, acquisition of information about one or more optional devices attached to the image forming apparatus, the acquired information including at least one of a model name, configuration information, and operation speed of the one or more optional devices attached to the image forming apparatus;
- and
- initializing, based on the acquired information about the one or more option devices, at least one of the processor and the one or more optional devices.

A non-transitory computer-readable storage medium storing a program that causes a computer to execute a method for controlling an information processing apparatus, to which an external device is attachable, the method comprising:
- determining, if the image forming apparatus is returned from a suspended state, whether there has been a change of an optional device attached to the image forming apparatus, the change of the optional device being at least one of an installation of a new optional device on the image forming apparatus, a removal of an optional device from the image forming apparatus, an addition of a new optional device, and a replacement of an optional device;
- shifting, in response to a detection of the operation to turn off a power switch, the power state of the image forming apparatus from a standby state to the power-off state even if the suspended state is set as the pre-set power state to which the image forming apparatus is to be shifted, in a case where it is determined that there has been the installation of the new optional device on the image forming apparatus, the removal of the optional device from the image forming apparatus, the addition of the new optional device, or the replacement of the optional device;
- executing, in a case where the image forming apparatus is activated from the power-off state, acquisition of information about one or more optional devices attached to the image forming apparatus, the acquired information including at least one of a model name, configuration information, and operation speed of the one or more optional devices attached to the image forming apparatus;
- and
- initializing, based on the acquired information about the one or more optional devices, at least one of the processor and the one or more optional devices.
