摘要： An ink jet recording system for performing recording by scanning a carriage having an ink jet recording cartridge, at least a part of which is removably mounted to said carriage, scans a carriage along a path that has a waiting position wherein access to the cartridge is inhibited and has a replacement position wherein the removably mounted part of the cartridge can be easily accessed, and in response to a cartridge replacement signal, moves the carriage to the replacement position. When the cartridge has been replaced, the carriage is returned to the waiting position.

摘要： An ink jet recording apparatus has a recording mode in which recording is performed by selectively discharging black ink and color inks of colors other than black. Any abnormality in the state of discharge of the ink is performed by executing a test discharging operation. When the recording apparatus functions as a facsimile apparatus, the test discharging operation is conducted by discharging only the black ink, without discharging inks of other colors. Wasteful consumption of ink is diminished, so that the running cost of the ink jet recording apparatus is reduced.
摘要翻译：喷墨记录装置具有通过选择性地排出黑色墨水和黑色以外的颜色的彩色墨水进行记录的记录模式。通过执行测试放电操作来执行墨水排出状态的任何异常。当记录装置用作传真装置时，通过仅放出黑色墨水而不排出其它颜色的墨水来进行测试放电操作。墨水的浪费消耗减少，从而降低了喷墨记录装置的运行成本。

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： 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.
摘要翻译：传真装置包括：传真单元，用于发送对应于已经接收的图像数据的数据;以及打印机单元，用于根据从传真单元发送的数据排出墨滴来执行图像记录。用于控制传真单元的第一CPU在一页图像数据之后以预定图案发送数据，并且进一步向打印机输送排纸命令。打印机单元的第二CPU在接收到排纸命令之后，在记录了预定图案之后执行排纸操作，并且在将记录纸传送到预定位置时，将用于开始检测预定图案的信号发送到第一个CPU。因此，第一CPU从光传感器接收检测信号。第二CPU进一步传送记录纸，并且在排出装置的定时，向第一CPU发送用于预定图案的检测结束的信号。因此，可以正确地检测记录在记录纸的尾部的墨的空白和记录纸卡纸的检测图案。

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： 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： 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.
