Abstract
An image forming apparatus includes a main power supply switch that turns on and off a main power supply, a battery that is a power source different from the main power supply, a detector that detects switching of the main power supply switch, and a first hardware processor that operates with power supplied from the battery, and provides a notification in response to the detector detecting the switching of the main power supply switch from on to off.
Claims14
An image forming apparatus comprising:
- a main power supply switch that turns on and off a main power supply;
- a battery that is a power source different from the main power supply;
- a detector that detects switching of the main power supply switch;
- a display;
- a notification unit that is configured independently from the display;
- a first hardware processor that:
- operates with power supplied from the battery,
- in response to the detector detecting the switching of the main power supply switch from on to off, drives the notification unit to continuously issue an external warning notification from the notification unit for a predetermined time to a user of the image forming apparatus to indicate that the main power supply switch has been turned off, and
- in response to the detector detecting the switching of the main power supply switch from off to on while the external warning notification is being issued, stops the driving of the notification unit to terminate the external warning notification;
- and
- a second hardware processor that updates firmware by executing a firmware update instruction provided from an external server, wherein
- in response to the detector detecting the main power supply switch being off at an update timing of the firmware, the first hardware processor awaits till the main power supply switch is turned on, and
- once the main power supply switch is turned on, the first hardware processor notifies, via the display, that the update timing has elapsed without updating the firmware.

A control method for an image forming apparatus that comprises:
- a main power supply switch that turns on and off a main power supply;
- a battery that is a power source different from the main power supply;
- a detector that detects switching of the main power supply switch;
- a display;
- a notification unit that is configured independently from the display;
- a first hardware processor that operates with power supplied from the battery;
- and a second hardware processor that updates firmware by executing a firmware update instruction provided from an external server, the method comprising:

- in response to the detector detecting the switching of the main power supply switch from off to on while the external warning notification is being issued, stopping the driving of the notification unit to terminate the external warning notification;
- in response to the detector detecting the main power supply switch being off at an update timing of the firmware, awaiting till the main power supply switch is turned on;
- and
- once the main power supply switch is turned on, notifying, via the display, that the update timing has elapsed without updating the firmware.

A control method for an image forming apparatus that comprises:
- a main power supply switch that turns on and off a main power supply;
- a battery that is a power source different from the main power supply;
- a detector that detects switching of the main power supply switch;
- a display;
- a notification unit that is configured independently from the display;
- a first hardware processor that operates with power supplied from the battery;
- and a second hardware processor that updates firmware by executing a firmware update instruction provided from an external server, the method comprising:
- acquiring update information designating an update timing of firmware;
- in response to the detector detecting the switching of the main power supply switch from on to off within a predetermined time period before the update timing, with power supplied from the battery, driving the notification unit to continuously issue an external warning notification from the notification unit for a predetermined time to a user of the image forming apparatus to indicate that the main power supply switch has been turned off;
- in response to the detector detecting the switching of the main power supply switch from off to on while the external warning notification is being issued, stopping the driving of the notification unit to terminate the external warning notification;
- with power supplied from the main power supply, updating the firmware by executing the firmware update instruction at the update timing;
- and
- in response to the detector detecting the main power supply switch being off at the update timing, awaiting till the main power supply switch is turned on, and once the main power supply switch is turned on, notifying, via the display, that the update timing has elapsed without updating the firmware.

A non-transitory computer-readable recording medium storing instructions to be executed by a hardware processor in an image forming apparatus comprising:
- a main power supply switch that turns on and off a main power supply;
- a battery that is a power source different from the main power supply;
- a detector that detects switching of the main power supply switch;
- a display;
- a notification unit that is configured independently from the display;
- a first hardware processor that operates with power supplied from the battery;
- and a second hardware processor that updates firmware by executing a firmware update instruction provided from an external server, the instructions causing the hardware processor to execute:
- operating with power supplied from the battery;
- in response to the detector detecting the switching of the main power supply switch from on to off, driving the notification unit to continuously issue an external warning notification from the notification unit for a predetermined time to a user of the image forming apparatus to indicate that the main power supply switch has been turned off;
- in response to the detector detecting the switching of the main power supply switch from off to on while the external warning notification is being issued, stopping the driving of the notification unit to terminate the external warning notification;
- in response to the detector detecting the main power supply switch being off at an update timing of the firmware, awaiting till the main power supply switch is turned on;
- and
- once the main power supply switch is turned on, notifying, via the display, that the update timing has elapsed without updating the firmware.
