Abstract
An image forming system comprising: an image forming apparatus capable of transitioning between a standby mode and a sleep mode; and a wireless operation device capable of wireless communication with the image forming apparatus, the wireless operation device including: a display; a battery configured to perform power supply to the display; and a controller configured to control the power supply from the battery to the display, wherein, in response to transition of the image forming apparatus from the standby mode to the sleep mode with a predetermined amount of power being supplied from the battery to the display, the controller makes a supply amount of power from the battery to the display less than the predetermined amount.
Claims20
An image forming system comprising:
- an image forming apparatus including an image forming unit configured to form an image on a sheet, the image forming apparatus being configured to accept an execution signal for the image forming unit to perform image forming, the image forming apparatus being capable of transitioning between a standby mode which is a power state enabling image forming to be performed in response to acceptance of the execution signal and a sleep mode which is a power state less in power consumption than the standby mode;
- and
- a wireless operation device configured to accept an operation from a user, the wireless operation device being capable of wireless communication with the image forming apparatus,
- the wireless operation device including:
- a display configured to display an image;
- a battery configured to perform power supply to the display such that the display lights up;
- and
- a controller configured to control the power supply from the battery to the display,
- wherein, in response to transition of the image forming apparatus from the standby mode to the sleep mode with a predetermined amount of power being supplied from the battery to the display, the controller makes a supply amount of power from the battery to the display less than the predetermined amount.
An image forming system comprising:
- an image forming apparatus including an image forming unit configured to form an image on a sheet, the image forming apparatus being configured to accept an execution signal for the image forming unit to perform image forming, the image forming apparatus being capable of transitioning between a standby mode which is a power state enabling image forming to be performed in response to acceptance of the execution signal and a sleep mode which is a power state less in power consumption than the standby mode;
- and
- a wireless operation device configured to accept an operation from a user, the wireless operation device being capable of wireless communication with the image forming apparatus,
- the wireless operation device including:
- a display configured to display an image;
- a battery configured to perform power supply in order to drive the wireless operation device;
- and
- a controller configured to switch an operation mode of the wireless operation device between a first power mode and a second power mode less in power consumption than the first power mode,
- wherein, when the image forming apparatus transitions from the standby mode to the sleep mode with the wireless operation device performing the first power mode, the controller switches the operation mode from the first power mode to the second power mode.
A wireless operation device configured to operate, via wireless communication, an image forming apparatus including an image forming unit configured to form an image on a sheet, the image forming apparatus being configured to accept an execution signal for the image forming unit to perform image forming, the image forming apparatus being capable of transitioning between a standby mode which is a power state enabling image forming to be performed in response to acceptance of the execution signal and a sleep mode which is a power state less in power consumption than the standby mode,
- the wireless operation device comprising:
- a display configured to display an image;
- a battery configured to perform power supply to the display such that the display lights up;
- and
- a controller configured to control the power supply from the battery to the display,
- wherein, in response to transition of the image forming apparatus from the standby mode to the sleep mode with a predetermined amount of power being supplied from the battery to the display, the controller makes a supply amount of power from the battery to the display less than the predetermined amount.
