Abstract: The inkjet printing apparatus is configured to be able to execute a batch adjustment process of performing a plurality of times of adjustment processes related to printing in succession based on one instruction from an outside. The conveyance control unit maintains the conveyance speed at a first speed in a period when a chart printing process is performed and a period when a chart imaging process is performed. The conveyance control unit decreases the conveyance speed from the first speed to the second speed after the end of the chart imaging process in an adjustment process except for an adjustment process that is performed last in the batch adjustment process, and increases the conveyance speed from the second speed to the first speed before the start of the chart printing process in an adjustment process that is performed next.

Abstract: After printing based on each job is ended, a printing control unit controls an operation of a printing unit so that an inspection pattern is printed on a print sheet in a period during which a conveyance control unit is keeping a conveyance speed of a print sheet at a constant speed. A maintenance content determination unit determines a maintenance content for the printing unit on the basis of an inspection result obtained by inspecting a print image for the inspection pattern. The printing control unit controls operations of the printing unit and a cleaning mechanism depending on the maintenance content determined by the maintenance content determination unit.
