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. 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.
