A function executing device is configured to send a wireless identifier to a communication device via a first type of wireless communication interface for setting up a wireless connection. The function executing device is configured to determine whether the function executing device is in an error state and, if not, to establish the wireless connection via a second type of wireless communication interface. The function executing device operates in a parent state in the wireless connection. Additionally, print data may be received from the communication device. However, if the function executing device is in an error state the wireless connection is not established via the second type of wireless communication interface.

A document scanner includes a casing and a document cover disposed above the casing. The casing includes a document glass and houses an image scanner. The document cover has one end portion and the other end portion opposite to the first end portion in a first direction and is configured to pivotally move about the one end portion between a closed position in which the other end portion covers the document glass and an open position in which the other end portion uncovers the document glass. The other end portion has an end surface that intersects, when the document cover is at the closed position, with an upper surface of the document glass. The end surface has an indication indicating a location to which an external device is to be brought into proximity to establish short-range wireless communication between the document scanner and the external device.

An image forming apparatus includes: an image former that executes image forming processing; a primary controller; a secondary controller that controls the image former; a sensor that detects a state of at least a unit of the image forming apparatus and transmits sensor data indicating the state to the secondary controller; a first transmission path for duplex communication between the primary and secondary controllers; and a second transmission path. The secondary controller: generates, from the sensor data, diagnostic data for failure diagnostics or life prediction, transmits data other than the diagnostic data to the primary controller via the first transmission path and transmits the diagnostic data to the diagnostic server via the second transmission path, or transmits data other than the sensor data to the primary controller via the first transmission path and transmits the sensor data to the diagnostic server via the second transmission path.

A communication apparatus has a communication function for performing wireless communication using one of a first mode of performing first communication with a partner apparatus via another apparatus, a second mode of performing second communication with the partner apparatus not via another apparatus, and a third mode of concurrently performing the first communication and the second communication. When the third mode is the operation mode of the communication function, the communication apparatus controls the communication function so as to activate a function of the second communication after executing processing to establish a connection for the first communication. When the connection has not been established even after a predetermined time has elapsed since the start of connection processing for the first communication, the function for the second communication is activated even if the connection for the first communication has not been established.

An information processing apparatus includes a first communication unit configured to communicate with a first communication apparatus; a second communication unit configured to wirelessly communicate with each of one or more second wireless communication apparatuses; an acquisition unit configured to acquire from the first communication apparatus via the first communication unit an apparatus ID that is held by the first communication apparatus and that is used for identifying one of the one or more second wireless communication apparatuses to or from which the second communication unit transmits or receives data; and a control unit configured to control the second communication unit to transmit or receive the data to or from the one of the one or more second wireless communication apparatuses that is identified by the apparatus ID acquired by the acquisition unit.

A communication apparatus includes: a first type communication unit configured to perform communication with a portable device in a near field communication mode; a display unit; and a control device configured to perform: a receiving process of receiving a radio wave for connection with the portable device in the near field communication mode, from the portable device through the first type communication unit; and a display process of controlling the display unit to display a notice for prompting a user to perform operation for permitting the portable device to transmit information to the communication apparatus in the near field communication mode, in response to receipt of the radio wave in the receiving process.
