Abstract:
In a line-head type inkjet printing apparatus that ejects a plurality of types of inks, an inkjet printing apparatus is provided in which the change of its ejection properties different depending on the type of ink is prevented from occurring. The line-head type printing apparatus includes an acquisition unit that counts the ejection number of liquid from each of print heads in each of a plurality of print heads. Furthermore, the printing apparatus compares the ejection number of liquid from each of the print heads counted by the acquisition unit with a threshold value set for each of the print heads. The printing apparatus includes a change unit that can move a holder in the main scanning direction when the counted ejection number of liquid exceeds the threshold value set for the print head.
