Image processing apparatus, apparatus, method of switching mode of the image processing apparatus, and non-transitory storage medium storing program executable by computer of the image processing apparatus

An apparatus, comprising:

• an engine including at least one of a print engine and a scanner engine, the print engine being configured to print an image on sheet, the scanner engine being configured to scan an image from document;
• an interface;
• a power source;
• and
• a controller configured to:
• select one of a plurality of power supply modes of the image processing apparatus, the plurality of power supply modes including:
• (i) a first mode, when the image processing apparatus is in the first mode, electric power being supplied from the power source to the engine and the interface;
• (ii) a second mode, when the image processing apparatus is in the second mode, supply of the electric power from the power source to the engine and the interface being in a stopped state;
• and (iii) a third mode, when the image processing apparatus is in the third mode, the supply of the electric power from the power source to the engine being in a stopped state, and the electric power being supplied from the power source to the interface;
• and
• switch the power supply mode from the second mode to the third mode in response to receiving a power supply request from an external device via the interface when the image processing apparatus is in the second mode.

A method of switching a mode of an image processing apparatus, the image processing apparatus comprising (i) an image-data processor configured to process image data, (ii) an interface configured to communicate with an external device, (iii) a power source, and (iv) a controller,

• wherein the method comprises:
• a step of causing the controller to select one of a plurality of power supply modes of the image processing apparatus, the plurality of power supply modes including:
• (i) a first mode, when the image processing apparatus is in the first mode, electric power being supplied from the power source to the image-data processor and the interface;
• (ii) a second mode, when the image processing apparatus is in the second mode, supply of the electric power from the power source to the image-data processor and the interface being in a stopped state;
• and (iii) a third mode, when the image processing apparatus is in the third mode, the supply of the electric power from the power source to the image-data processor being in a stopped state, and the electric power being supplied from the power source to the interface;
• and
• a step of causing the controller to switch the power supply mode from the second mode to the third mode in response to receiving a power supply request from an external device via the interface when the image processing apparatus is in the second mode.

A non-transitory storage medium storing a program executable by a computer of an image processing apparatus, the image processing apparatus comprising (i) an image-data processor configured to process image data, (ii) an interface configured to communicate with an external device, and (iii) a power source,

• wherein when executed by the computer, the program causes the image processing apparatus to select one of a plurality of power supply modes of the image processing apparatus, the plurality of power supply modes including:
• (i) a first mode, when the image processing apparatus is in the first mode, electric power being supplied from the power source to the image-data processor and the interface;
• (ii) a second mode, when the image processing apparatus is in the second mode, supply of the electric power from the power source to the image-data processor and the interface being in a stopped state;
• and (iii) a third mode, when the image processing apparatus is in the third mode, the supply of the electric power from the power source to the image-data processor being in a stopped state, and the electric power being supplied from the power source to the interface, and
• wherein when executed by the computer, the program causes the image processing apparatus to switch the power supply mode from the second mode to the third mode in response to receiving a power supply request from an external device via the interface when the image processing apparatus is in the second mode.
