发明名称 Ink jet printing apparatus and preliminary ejecting method
摘要 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.
