Embodiment Construction

[0051] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0052] figure 1 A facsimile machine 100 employing a printing device according to an embodiment of the present invention is shown. FIG. 2 is a cross-sectional view of the facsimile machine 100, showing the internal structure of the facsimile machine. The facsimile machine 100 includes a printing device using an inkjet printing method (hereinafter referred to as an inkjet printer), an image reading device (hereinafter referred to as a scanner), a sending device, and the like.

[0053] The facsimile machine 100 is constructed so that when it is connected to a personal computer or the like, the facsimile machine 100 can be used as an ink jet printer and / or a scanner. In addition, when an image can be read using a scanner, and the scanned image is printed using a printer, the facsimile machine 100 can be used as a copier. In the following description, since the scanner an...

Abstract

A printing device includes a sheet feeding mechanism that feeds the recording sheet by a predetermined amount at a time, a carriage that is movable, substantially at a constant speed, in a direction substantially perpendicular to a sheet feeding direction, and a print head mounted on the carriage. The print head is capable of simultaneously forming a plurality of print lines when the carriage moves. The print head is controlled to print a first print pattern that is formed by part of the plurality of print lines on an upstream side. The recording sheet is fed by the predetermined amount after the first pattern is formed. Thereafter, a second print pattern that is formed by part of the plurality of print lines on a downstream side after the recording sheet is fed. At least a part of the first print pattern overlaps a part of the second print pattern.

Description

technical field [0001] The invention relates to an inkjet printing device and a method for controlling an inkjet printing device. Background technique [0002] Inkjet printing devices usually have a movable support for mounting a print head, and the print head has a plurality of nozzle arrays. The support can move along a direction substantially perpendicular to the paper feeding direction, while the nozzle array extends along the paper feeding direction. The inkjet printing device is generally controlled so that the paper and the support are driven alternately, and the print head (ie nozzle array) is controlled to spray ink to the paper according to the printing data when the support moves. This printing method is recognized as a cross printing method. [0003] Currently, various improvements have been proposed to increase the printing speed, improve the image quality of printing, and the like. For example, in order to speed up the printing speed, the nozzle array is ext...
