Abstract
An ink ejecting printer capable of increasing a printing speed by eliminating unnecessary head maintenance operations includes a mode controller, a ROM, timing value storage, a wiping ordering unit and a suction ordering unit. When a normal print mode is selected, the mode controller supplies the timing value storage with the initial values of the wiping and suction timings held in the ROM; when a thin-out mode is selected, the mode controller supplies the storage with changed values. The timing value storage stores the wiping and suction timings sent from the mode controller. When a print operation is started, the wiping ordering unit and suction ordering unit retrieve the values of the wiping and suction timings from the timing value storage. When the print operation is found to have reached one of the timings, the corresponding unit suspends the printing and causes the appropriate wiping or sucking operation to be carried out. This makes it possible, when the thin-out mode is selected, to reduce unnecessary head maintenance operations and thereby increase the printing speed.
