Abstract
An image forming apparatus includes an image forming unit configured to form an image on a sheet based on image data, a control unit configured to control driving of the image forming unit, and a power supply unit configured to, if a factor for shifting from a power saving state to a standby state is detected, supply power to the image forming unit and the control unit. If a first type of factor is detected as the factor in the power saving state, the power supply unit supplies power to the control unit and the image forming unit, and the control unit restricts the driving of the image forming unit. If an instruction to perform a function of forming an image on a sheet is accepted, the control unit cancels restriction of the driving of the image forming unit.
Claims14
An image forming apparatus comprising:
- a motor configured to cause a photosensitive drum of the image forming apparatus to rotate;
- a scanner unit including a scanner drive unit configured to drive for reading a document;
- a display configured to display information;
- a human sensor capable of sensing a human;
- and
- one or more processors, the one or more processors being configured to:
- cause the display to display at least a copy button for selecting a copy function and another button for selecting another function on the display, based on a sensing of the human sensor in a state that the copy button and the another button are not displayed on the display,
- cause the motor to drive, without operation on a start button to start copying, based on a selection of at least the copy button for selecting the copy function displayed on the display, and not to cause the motor to drive based on the sensing of the human sensor in a state that the copy button and the another button are not displayed on the display,
- cause the scanner drive unit to activate based on detecting of a document on a tray, and
- cause the image forming apparatus to print an image on a recording medium based on an operation on the start button after selection of the copy button.
A control method of controlling an image forming apparatus including a motor configured to cause a photosensitive drum of the image forming apparatus to rotate, a scanner unit including a scanner drive unit configured to drive for reading a document, a display configured to display information, a human sensor capable of sensing a human, the method comprising:
- displaying at least a copy button for selecting a copy function and another button for selecting another function different from the copy function on the display, based on a sensing of the human sensor in a state that the copy button and the another button are not displayed on the display;
- causing the motor to drive, without operation on a start button to start copying, based on a selection of at least the copy button for selecting the copy function displayed on the display, and not causing the motor to drive based on the sensing of the human sensor in a state that the copy button and the another button is not displayed on the display;
- activating the scanner drive unit based on detecting of a document on a tray;
- and
- printing an image on recording medium based on the operation on the start button after selection of the copy button.
