) Description of other embodiments Effects of the invention [Summary] Regarding an inkjet head cleaning method for removing paper powder, scum, etc. from around the nozzle surface of an inkjet head that ejects ink from a nozzle, a wiper is used to clean the nozzle. In an inkjet head cleaning method that uses a wiper to scrape off the nozzle surface of an inkjet head that ejects ink from a nozzle, the purpose is to prevent nozzle jetting abnormalities from occurring even if the surface is scraped off. During operation, the wiper operates while ink oozes out from the nozzle by pressurizing the ink supplied to the inkjet head.
本発明は、インクをノズルから噴射するインクジェット

ング方法に関する。The present invention relates to a cleaning method for an inkjet head that ejects ink from nozzles, and for removing paper dust, scum, etc. from around the nozzle surface of the head.
インクジェットプリンタは、印刷媒体に非接触なヘッド
からインクの微小な粒子を直接印刷媒体に吹きつける方
式であるため、印刷媒体に対する制限が少ない、カラー
印刷が容易に実現できる、高速印字ができる、印字騒音

電型、バブルジェット型等種々のものが市場に提供され
ている。Inkjet printers spray tiny particles of ink directly onto the print medium from a head that does not contact the print medium, so there are fewer restrictions on the print medium, color printing can be easily achieved, high-speed printing is possible, and printing is possible. It has the feature of almost no noise, and various types such as piezoelectric type, electrostatic type, and bubble jet type are provided on the market.
しかし、インクという液体を取り扱うため、ノズルの目
詰まりが生じやすいという欠点を持っており、目詰まり
を防いだり復旧させたりする機構（以下バックアップ機
構と呼ぶ）が必須である。However, because it handles a liquid called ink, it has the disadvantage that the nozzles are easily clogged, and a mechanism (hereinafter referred to as a backup mechanism) to prevent or recover from clogging is essential.
従来のバックアップ機構の構成としては、ヘッドのノズ
ル面周辺に付着した紙粉やほこりを下方へかき落とすた
めのワイパと、ノズル内に入った気泡や増粘したインク

ンクを押し出す機構とを組合わせたものが知られている
。Conventional backup mechanisms consist of a wiper that scrapes paper powder and dust stuck around the nozzle surface of the head downwards, and a mechanism that sucks out air bubbles and thickened ink that have entered the nozzle from the nozzle side. Alternatively, a combination of a mechanism for pushing out ink from the supply side is known.

ズル面周辺のほこりや紙粉や増粘したインクを°かき落
としたあと、ヘッド内のインクを吸出したり、押し出し
たりして、クリーニングを行っていた。Conventionally, inkjet printers with this type of backup mechanism first operate the wiper to scrape off dust, paper powder, and thickened ink around the nozzle surface of the head, and then suck out or push out the ink inside the head. I was doing some cleaning.
従来技術では、ワイパがノズル付近をこする際に、ノズ

クを流せばノズルが正常な状態に戻せると考えているた
め、ワイパの動作終了後、ヘッド内のインクを吸出した
り、押し出したりしていた。With conventional technology, when the wiper scrubs around the nozzle, it may push air bubbles or dust into the nozzle, so even if such a problem occurs, if you continue to flow ink, the nozzle will return to normal. Thinking that the condition could be restored, the ink inside the head was sucked out or pushed out after the wiper operation was completed.

後にインクを流してもこれらを完全に復旧させることが
できない場合があるという問題があった。However, in reality, after this series of operations, a nozzle that was ejecting ink normally before the operation may malfunction in ejection. In other words, some of the dust adhering to the area around the nozzle is quite firmly attached, and in order to scrape it off, the wiper rubs the nozzle surface quite strongly, causing air bubbles and minute dust to get inside the nozzle. There was a problem in that there were a considerable number of cases in which such intrusions occurred, and even if ink was subsequently flushed, these problems could not be completely restored.
従って、本発明は、ワイパでノズル面をかき落としても
、ノズルの噴射異常が発生することを防止することので

行う。During normal printing, a meniscus is formed in the head nozzle section due to negative pressure in the ink chamber 22 of the head 2, and the head 2 is moved in the longitudinal direction of the platen 8 by the carriage drive section 10 while being driven by the head drive from the control section 12. A piezoelectric element (not shown) facing the ink chamber 22 is driven by the signal, and ink is ejected to print on the paper PP on the platen 8.
この時、インク加圧部６でインクの加圧は行われない。At this time, the ink pressure unit 6 does not pressurize the ink.

成される。After that, the control unit I2 releases the pressure applied by the ink pressurizing unit 6. This stops the ink from seeping out from the nozzle surface 20, and the ink meniscus is re-formed in the nozzle portion 20.
■ そして、印字を開始する。■ Then, start printing.
