Abstract: A peripheral unit is controlled by means of a driver in another apparatus, where an instruction sent to the peripheral unit contains both data produced by the driver and data produced by another application in the other apparatus. This is done by subjecting the instruction received from the other apparatus to processing in which the data produced by the other application is deleted.

Abstract: An existing printer arranged to print data from a PC (personal computer) is used as the printer unit of a facsimile apparatus. The PC uses a printer driver dedicated to an existing printer (capable of performing the same processing as the printer unit of the facsimile apparatus) as a module, serving as application software for a facsimile-apparatus control unit, for printing the data from the PC. When printing data from the PC, a command uniquely directed to the facsimile apparatus is added to the printing data generated by the PC's printer driver, and the resultant data is transmitted to the facsimile apparatus. Upon receipt of the transmitted data, the facsimile apparatus removes the added command, thus restoring the printing data generated by the printer driver, and transmits the restored data to the printer unit to perform printing.

Abstract: An image reading apparatus individually reads a predetermined white reference plate by flickering light sources of the respective colors before an original image is read by sequentially turning on the light sources during one line sync period. The flickering duty ratio of the light source obtained when the white reference plate is read is set for each color so as to maximize the output value from an A/D converter within its predetermined conversion range. When an original is read, the image reading apparatus changes the emission color by switching the light source to be flickered every line sync period, and turns on the light sources of the respective colors in accordance with different duty ratios set for these colors.

Abstract: A facsimile apparatus is equipped with an ink jet printing unit, capable of reducing the number of ink discharge recovery operations of the ink jet recording head, thereby reducing the ink consumption. The received image data are stored in an image memory with inspection for errors in transmission in an error correction mode, and are collectively printed after a predetermined amount of image data are stored. The recording head is uncapped in response to receipt of a first procedure signal indicating the predetermined amount of image data being transmitted from a transmitting unit and in response to receipt of a second procedure signal, different from the first procedure signal, indicating one page of image data being transmitted from a transmitting unit.

Abstract: 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.

Abstract: 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.

Abstract: A recording apparatus includes a recording unit for ejecting an ink to a recording member, a detection unit for detecting a remaining amount of ink, a memory for storing received data, and a control unit for controlling an operation of the recording unit to record an image in accordance with the received data, and controlling the memory to store image data in the memory. The control unit controls the memory in accordance with an output from the detection unit upon completion of recording of a predetermined volume of data, clears data stored in the memory when the output from the detection unit indicates a presence of ink, and preserves data stored in the memory when the output from the detection unit indicates an absence of ink.

Abstract: An image communication apparatus, for recording an image using a recording head for ejecting an ink from an ejection port by utilizing energy generated by an ejection energy generation element, includes a communication section for communication a procedure signal associated with a communication and image data, a driving section for driving the recording head in accordance with the image data received by the communication section, a preservation section for performing preservation processing of the recording head, and a control section for discriminating a procedure signal transmitted after the image data, and controlling an operation of the preservation section on the basis of the discrimination result. When the control section discriminates that a specific procedure signal for successively performing reception is transmitted, it causes the preservation section to execute the preservation processing.

Abstract: A drive control system for a stepping motor which stores values for the current driving each phase of the motor in data tables. A central processing unit drives the motor in accordance with the current values stored in the data tables. The current values are stored in the data table with corresponding addresses. The current values are read out sequentially from the addresses in the data tables. Each time the address is incremented by 1, the magnitude of the angle of rotation of the motor is set so that it is always the same.
