Problems solved by technology

However, in the above-mentioned steps, more ink is discarded than used in printing, and the ink is uselessly consumed.
In addition, forcible ejection of ink is performed not only in nozzles that do not eject ink, but also in nozzles that have ejected ink, so it is not effective.

Embodiment Construction

[0028] Hereinafter, embodiments of the present invention will be described with reference to the drawings. figure 1 It is a side view schematically showing a schematic configuration of an inkjet recording device 100 of the present invention for recording ink on a recording medium, figure 2 is viewed from above figure 1 It is a plan view of the first transport unit 5 and the recording unit 9 of the inkjet recording device 100 shown. In addition, although paper is described here as an example of the recording medium, the recording medium is not limited to paper, and the recording medium may be cloth, an OHP sheet, or the like.

[0029] Such as figure 1 As shown, a paper feed tray 2 for accommodating paper P is provided on the left side of the inkjet recording apparatus 100, and a paper feed roller 3 and a driven roller 4 are provided at one end of the paper feed tray 2. The paper roller 3 is used to convey the stored paper P one by one starting from the uppermost paper P to ...

Abstract

An inkjet recording device (100) includes a recording head (17), a head driving unit (25), and a controller (20). A selector (30) of the head driving unit (25) performs selection for individual nozzles so that when the drive waveform selection data for printing one line at this time sent from a data processing section (23) indicates that the number of times of ink ejection is 0, and drive waveform selection data for printing the next one line indicates that the number of times of ink ejection is 0, drive voltage according to none of one or more drive waveforms for ink ejection or a drive waveform for meniscus oscillation is applied to a piezoelectric element (31).

Description

technical field [0001] The present invention relates to an inkjet recording device and an image forming device that perform recording by ejecting ink onto a recording medium such as paper in a recording device such as a facsimile machine, a copier, or a printer. Background technique [0002] Recording devices such as facsimile machines, copiers, and printers are configured to record images on recording media such as paper, cloth, and sheets for OHP. However, they can also be classified into inkjet type, dot matrix type, thermal type, etc. according to the method of recording. . In addition, examples of inkjet recording methods include a continuous type and a line scanning head type. In the continuous inkjet recording method, for example, recording is performed while scanning the recording head on the recording medium. In the line scan head type inkjet recording method, for example, recording is performed by a single pulse method (one pass method). In an inkjet recording a...
