    • The present invention provides an ink jet printing apparatus including feeding structure for feeding a print medium into the printing apparatus, conveying structure for conveying the print medium fed by the feeding structure to a position where printing head can carry out printing, and scanning structure for moving and scanning a carriage to a position where the printing head can be subjected to preliminary ejection, wherein a paper feeding and conveying operation is performed simultaneously with a preliminary ejecting operation of a print head, while not all of the feeding structure, conveying structure, and scanning structure are simultaneously driven. Therefore, by providing a power supply capacity sufficient to drive two of the three structures, it is possible to cause the print head to perform a preliminary ejecting operation without suspending the operation of feeding and conveying the print medium.
    • 本发明提供了一种喷墨打印设备,其包括用于将打印介质供给到打印设备中的进给结构,用于将由进给结构馈送的打印介质传送到打印头可执行打印的位置的传送结构,以及用于移动的扫描结构 并且将滑架扫描到打印头可以进行预喷射的位置,其中与打印头的预喷射操作同时进行送纸和输送操作,而不是全部进给结构,输送结构和 扫描结构同时驱动。 因此,通过提供足以驱动三个结构中的两个的电力供应能力,可以使打印头执行预备喷射操作,而不会暂停进给和传送打印介质的操作。
