A facsimile apparatus includes a storage unit, a first detection unit, and a second detection unit. The storage unit stores a parameter based on a connection standard of a telephone-line connected to the facsimile apparatus, and an apparatus direct-current resistance of the facsimile apparatus. The first detection unit detects a first voltage that is a voltage at a line-open time of a telephone line connected to the facsimile apparatus. The second detection unit detects a second voltage that is a voltage at a line-capture time of the telephone line. By using the first voltage, the second voltage, the parameter, and the apparatus direct-current resistance, a voltage to be a threshold for determination of line capture is determined. By using a voltage detected from the telephone line and the voltage to be the threshold determined by the first determination unit, whether the telephone line is captured is determined.

A device which is capable of minimizing the use of resources in devices and safely communicating information such as settings on devices. The device is capable of communicating with another device via a wireless communication network and manages the other device. The device leaves a first wireless communication network to which the device is currently connected. Then, the device wirelessly connects to the other device so as to construct, with the other device that left the first wireless communication network after the device, a second wireless communication network, which is different from the first wireless communication network, by using a setting network ID for use in a setting change mode for changing setting values of the other device. The device sends setting data to the other device, to which the device was wirelessly connected, via the second wireless communication network.

A display control system includes a division unit configured to divide a display screen into plural areas, a display unit configured to display data in each of the plural areas, and a setting unit configured to set any one of plural data transfer modes to each of the plural areas according to an instruction by a user, without changing a type of display data to be displayed in each of the plural areas. In addition, a transfer unit is configured to transfer, for each of the plural areas, display data to be displayed in the area in the data transfer mode set to the area by the setting unit. The display unit displays the display data transferred by the transfer unit in the area among the plural areas and corresponding to the type of display data.

Image processing device, control method of image processing device, and storage medium

An information processing apparatus sets a driving keeping voltage for keeping driving of a fan to a voltage that is higher than a voltage that is applied to the fan when the fan is determined not to be rotating after decreasing the voltage that is applied to the fan in a state where the fan is rotating.

Communication system capable of speech and facsimile communication

A facsimile apparatus comprises a facsimile unit for sending data corresponding to image data that has been received, and a printer unit for performing image recording by discharging ink droplets in accordance with data sent from the facsimile unit. A first CPU for the control of the facsimile unit sends, after one page of image data, data in a predetermined pattern and further a paper exhausting command to the printer. A second CPU of the printer unit performs a paper exhausting operation upon receiving the paper exhausting command, after recording of the predetermined pattern, and upon conveying the recording paper up to a predetermined position, sends a signal for starting detection of the predetermined pattern to the first CPU. The first CPU thereby receives a detection signal from a photo sensor. The second CPU further conveys the recording paper, and at a timing of exhausting out of the apparatus, sends a signal for the detection end of the predetermined pattern to the first CPU. Thereby, it is possible to detect correctly the pattern for detection of the emptiness of ink and the recording paper jam which is recorded at the trailing portion of the recording paper.

Recording apparatus

A standard print mode or a thinning print mode can be selected at will by an input from an operation panel to record image data received by a receiving means section in a selected print mode using an ink jet recording head, And after one page of image recording, a footer mark is recorded on the trailing portion of the recording paper, and sensed by a photo sensor to determine whether or not the ink is present. This footer mark is recorded in the standard print mode without regard to the selected print mode. Thereby, the false detection of the predetermined image recorded on the recording medium, after a predefined amount of image data has been recorded, can be prevented.
