摘要： Printer performs accurate ink-discharge status detection, dependent upon the type of a printhead attached to the printer, the print mode and the color of ink change, and a facsimile apparatus using the printer. Each time printing based on received facsimile image data for one page of print sheet has been completed, the printhead is moved to a position close to a photosensor, and test ink discharge is performed. At this time, the type of printhead is determined, and whether or not the color printhead is in normally-dischargeable status is judged by comparing a pulsewidth obtained from output from the photosensor with a threshold value selected in accordance with the discrimination result. Otherwise, one of a plurality of threshold values according to print modes and ink colors is read from a ROM, and test ink discharge is performed with respect to corresponding color ink. The result of the discharge is compared with the threshold value. Thus, whether or not the printhead is in normally-dischargeable status is judged with respect to each color ink.

摘要： A printer which can perform color printing by using a plurality of color ink, and if some color ink is exhausted, prevents wasteful consumption of other color ink, and a facsimile apparatus, using the printer, which enables to confirm whether or not printing based on received facsimile image data using ink has been normally performed. In a case where printing is performed based on print data from an external computer, printhead 5 is moved to a position opposite to photosensor 8, and test ink discharge is performed with regard to all the plurality of color ink prior to print operation. If it is judged that even one of the plurality of color ink is exhausted, print operation is not performed. In case of printing based on facsimile reception image data, test ink discharge is performed after the print operation. If it is judged that ink is exhausted, received image data is stored into an image memory.

摘要： A plurality of ejection openings of an ink-jet head are divided into four blocks and ink ejection is performed for each block. An output of a photosensor which depends upon a number of ejected ink droplets interrupting light at a photosensor is sampled. On a basis of the sensor output, judgement is made whether ejection failure is present of the relevant block. This in ejection openings process is performed sequentially for other blocks. By this, even when a given rate of error is present in detecting precision of the photosensor, since overall number of ejection openings for which the detection is made is smaller, the number of faulty ejection openings which cannot be detected can be made smaller.

摘要： In an ink-jet printing apparatus employing an ejection failure detecting construction for optically detecting the number of ink droplets interrupting a light path, when a power source for an apparatus is turned on, a home position is detected. A carriage is shifted from this point at a constant speed, and ink ejection is performed sequentially within zones P1 to P2 where a photosensor is present. Then, among variations of output of the photosensor by sequential ink ejection, the number of steps S of a motor up to a timing where the maximum output Vmax is output. In a subsequent process for detecting ejection failure, ejection is performed at this position.

摘要： 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.

摘要： A wheel for maintaining a constant distance between an ink discharge plane of a recording head and a recording sheet is provided on a carriage such that it is upstream of the recording head as viewed in the direction of movement of the recording head in a unidirectional print mode. A sensor monitors whether the recording sheet is moved off a contact of a feed roller which feeds the recording sheet to a record position and a pinch roller. Before a trailing edge of the recording sheet is moved off the contact of the feed roller and the pinch roller, bilateral recording is conducted to print in each of forward movement and backward movement of the carriage. When the sensor detects that the trailing edge of the recording sheet has been moved off the contact of the feed roller and the pinch roller, the recording is switched to unilateral printing. The print range at the trailing edge of the recording medium is thus extended.

摘要： To provide a reading/printing apparatus and a reading apparatus by which the facility with which each unit is assembled and maintained can be significantly improved because steps of fixing and connecting individual units need not be performed in order, a printing apparatus, a control board, and a power supply are disposed inside a housing obtained by integrally forming a base portion serving as a bottom surface, side walls serving as outer side surfaces, and an opening surrounded by the side walls. The reading apparatus, the printing apparatus, the control board, and the power supply are discretely constituted. The housing includes a first housing integrally formed with enough strength to separately fix the base portion, lower portions of the side walls, the reading apparatus, the printing apparatus, the control board, and the power supply, and a second housing covering the opening and integrally forming upper portions of the side walls. The second housing is fixed to the first housing by elastic deformation so as to cover the opening of the first housing.

摘要： If one page of recording is terminated, a carriage moves to a position at which a recording head is located opposite a cap. Then, the ink is discharged through nozzles of the recording head onto temperature detecting element within the cap. Temperature change of the temperature detecting element upon contact with the ink is output from a detecting circuit, and the normal discharge of ink is detected by discharge detecting means. In this way, a decrease in the ink remaining or the detection of ink nondischarge can be securely made.
