【Example】

(Embodiment 1) In this embodiment, a case where the present invention is applied to a color recording system will be described.

(1) Description of Color Recording Apparatus FIG. 6 is a schematic perspective view showing the configuration of an embodiment of a color ink jet recording apparatus to which the present invention can be applied.

In this figure, 202 is an ink cartridge. These are composed of an ink tank containing four color inks (black, cyan, magenta, and yellow), respectively, and a recording head 201. This cartridge can be attached to and detached from the carriage, and a cartridge of three color inks or a monochrome black cartridge can be attached.

Reference numeral 103 denotes a paper feed roller which rotates in the direction of the arrow in the figure while holding the printing paper 107 together with the auxiliary roller 104 to feed the printing paper 107 and
Like 3, 104, it also plays a role of suppressing the printing paper 107. A carriage 106 supports four ink cartridges, and moves the ink cartridge 202 and the recording head 201 to be mounted together with printing. The carriage 106 is controlled so as to stand by at the home position shown by the dotted line in the figure when the printing apparatus is not printing or when the print head recovery operation is performed.

Before the start of printing, the carriage 106 located at the position shown in the figure (home position) moves in the x direction while driving the recording element provided in the recording head 201 to move the recording element on the paper surface. The area corresponding to the recording width of the recording head is printed. When printing is completed up to the edge of the paper along the scanning direction of the carriage, the carriage returns to the original home position, and printing is performed again in the x direction. After the previous print scan is completed and before the next print scan is started, the paper feed roller 103 rotates in the direction of the arrow shown in the drawing to feed the paper in the y direction by the required width. In this way, by repeating the main scanning for printing and the paper feeding, the printing on one paper surface is completed. The recording operation of ejecting ink from the recording head is performed under the control of a recording control unit (not shown).

Further, in order to increase the printing speed, printing is not performed only in the main scanning in one direction, but printing is also performed in the returning path when the carriage is returned to the home position side after the printing in the x direction is finished. It may be configured to perform.

Further, in the example described above, the ink tank and the recording head are held by the carriage 106 in a separable manner. It may be an ink jet cartridge in which an ink tank 202 for containing recording ink and a recording head 201 for ejecting ink toward the recording paper 107 are integrated.

Further, the circuit connecting portion 311 on the silicon plate and the printed board 309 are connected by the ultrafine wire 310, and the signal from the recording apparatus main body is received through the signal circuit 312. The liquid passage 302 and the common liquid chamber 301 are formed by a plastic cover 306 made by injection molding. Common liquid chamber 301
Is connected to the above-described ink tank (see FIG. 6) via the joint pipe 304 and the ink filter 305, and ink is supplied from the ink tank to the common liquid chamber 301. The ink supplied from the ink tank to the common liquid chamber 301 and temporarily stored therein enters the liquid passage 302 by a capillary phenomenon, forms a meniscus at the ejection port 300, and keeps the liquid passage 302 filled. At this time, when the recording element 303 is energized via an electrode (not shown) to generate heat, the ink on the recording element 303 is rapidly heated to generate bubbles in the liquid path 302, and the expansion of the bubbles causes the ejection port to expand. Ink droplets 313 are ejected from 300.
