An image forming system includes: an information processing apparatus configured to output information related to a print job to form an image on a recording medium, the image forming apparatus being configured to be operable in a plurality of power modes including a first normal power mode in which the information is output and a first power saving mode in which power consumption is less than the first normal power mode; and an image forming apparatus having: an image forming unit configured to form an image on the recording medium based on the print job output from the image processing apparatus, and an operation unit to be operated by a user to instruct to form the image by the image forming unit.

A controller of an image processor, when detecting a portable terminal device’s presence, accepts a selecting operation to select whether or not to refer to an address book held by a portable terminal device (step S32), when accepting the request for referring to the address book, establishes a near field communication with the portable terminal device (Step S34), and acquires, from the portable terminal device, the destination information in the address book (Step S35). When acquiring the destination information in the address book, the controller generates a destination list based on the destination information (Step S36), accepts a selecting operation to select a destination of the image data from the destination list (Step S37), and sends the image data to the accepted destination (Step S39).

An image forming system includes an information processing apparatus configured to output, to an image forming apparatus, information about an image forming job to form an image on a recording medium, the image forming apparatus being configured to be operable in a plurality of power modes including a normal power mode in which the information is output and a power saving mode in which power consumption is less than the normal power mode; an image forming apparatus includes a storage unit configured to store the information about two or more image forming jobs output from the information processing apparatus; and an image forming unit configured to form an image on the recording medium based on the information stored in the storage unit.

An image forming apparatus 1 (a) displays a visible code in which network identification information of the image forming apparatus 1 is encoded and a function code corresponding to a function of the image forming apparatus 1, (b) transmits function designation screen data to the portable terminal device 2 connected by using the network identification information, (c) receives a function code input to a function designation screen based on the function designation screen data from the portable terminal device 2 via a network, (d) determines whether the received function code matches the displayed function code or not, (e1) transmits operation screen data corresponding to the function code to the portable terminal device 2 via the network when both match, and (e2) does not transmit operation screen data to the portable terminal device 2 when both do not match.

An electronic apparatus includes a power source, a power monitoring unit configured to monitor an output voltage output from the power source, an acceptance unit configured to accept a user operation to turn off the electronic apparatus, and an execution unit configured to operate using power output from the power source, execute shutdown processing in response to the user operation accepted through the acceptance unit, and execute the shutdown processing when the output voltage monitored by the power monitoring unit is lower than a threshold voltage. The threshold voltage is higher than a guaranteed operation voltage of the execution unit.

An image forming apparatus includes: a human presence sensor that detects a user who uses the image forming apparatus; a first covering provided in front of the human presence sensor; and a second covering provided in front of the first covering, the second covering being configured not to interfere with detection of a detection target by the human presence sensor.

An image forming apparatus includes an operating key, an illuminance sensor, and a controller. The operating key contains a lamp. The illuminance sensor detects an ambient illuminance. The controller controls turning on and off of the lamp. The operating key functions as a first trigger for return from a power-saving mode to a normal mode. The controller turns the lamp off when the ambient illuminance detected by the illuminance sensor in the power-saving mode is equal to or more than a first threshold value, and the controller turns the lamp on when the ambient illuminance detected by the illuminance sensor in the power-saving mode is less than the first threshold value.

A non-transitory computer-readable recording medium stores a program executable by an information processing apparatus configured to communicate with a device including a first element and a second element, the second element being configured to receive power from a power source, and the first element being configured to receive the power from the power source via the second element. The program includes instructions that when executed by a processor of the information processing apparatus cause the information processing apparatus to control the second element such that the second element is maintained in a power state in which the second element supplies the power to the first element.

An image reading apparatus executes a calibration processing of calibrating a reading unit when a medium detection sensor detects that a medium is present. The image reading apparatus executes the calibration processing each time a first time-period elapses in a state where the medium detection sensor detects that the medium is present after the calibration processing. When a start instruction of reading the medium is received, the image reading apparatus starts transport of the medium and causes the reading unit to read the medium on a basis of calibration information of a last calibration processing.

A terminal device includes a communicator capable of communicating with a plurality of image forming apparatuses capable of switching an operation mode between an energy-saving mode and a normal mode, and a controller, wherein the controller, from the plurality of image forming apparatuses via the communicator, receives information of each image forming apparatus including the operation mode, based on the information of each image forming apparatus, displays states of the operation modes of the image forming apparatuses, and sends a request signal, which switches the operation mode, via the communicator to the image forming apparatus selected from among the displayed image forming apparatuses.
