Image forming apparatus, and method for controlling image forming apparatus

A method for controlling an image forming apparatus that is able to shift to a power saving state, the image forming apparatus including a printer which performs printing processing, a first controller which outputs a drive signal for at least one motor provided in the printer, a switch located between the at least one motor and a power supply which outputs power to the at least one motor, and a second controller which turns on the switch and turns off the switch, the method comprising:

• receiving a return instruction;
• and
• storing information indicating an initial screen, preset by a user, to be displayed when a user interface receives the return instruction,
• wherein when the user interface receives the return instruction in the power saving state, the second controller turns on the switch, and outputs a predetermined signal to a first controller or does not output the predetermined signal to the first controller based on the information stored in the storage, and
• wherein the first controller is able to output the drive signal while the predetermined signal is not input and does not output the drive signal while the predetermined signal is input.

An image forming apparatus that is able to shift to a power saving state, comprising:

• a printer which performs printing processing;
• a first controller which controls driving of the printer;
• a power supply which outputs power to at least one device in the printer;
• a switch arranged between the at least one device in the printer and the power supply;
• a second controller which turns on the switch and turns off the switch and outputs a predetermined signal to the first controller;
• a user interface which receives a return instruction;
• a display;
• and
• a storage which stores information indicating an initial screen, preset by a user, to be displayed when the user interface receives the return instruction,
• wherein, in accordance with receiving the return instruction in the power saving state, the second controller
• (i) turns on the switch, and
• (ii) outputs the predetermined signal to the first controller or does not output the predetermined signal to the first controller based on the information stored in the storage.
