摘要： An object of this invention is to prevent prolongation of the time taken for a suction recovery operation while suppressing wasteful consumption of ink in the suction recovery operation. An ink-jet printing apparatus includes a plurality of caps which, when a plurality of nozzles of an ink-jet head are divided into a plurality of nozzle groups, are arranged one by one for the respective nozzle groups, and cap the respective nozzle groups, a suction pump which generates a negative pressure in the plurality of caps to suck ink from the plurality of nozzles, and is arranged commonly for the plurality of caps, and a control unit which controls the suction pump so as to make the negative pressure by the suction pump act on all the caps when a common negative pressure is generated in the plurality of caps, and make different negative pressures by the suction pump act sequentially on the plurality of caps when different negative pressures are generated in the respective caps.

摘要： A plurality of ejection portions are divided into groups, each containing at least one ejection portion, so that the suction-based recovery operation can be performed for each group independently. Since the number of ejection portions contained in each group differs, if an ink flow resistance varies among the different groups, simultaneous suction-based recovery operations can be done by using a common suction pump, without having to sequentially perform the suction-based recovery operations under an optimum pump driving condition. For this purpose, inner diameters of a plurality of ink discharge tubes running from a plurality of cap units, which cap a plurality of print head units having different numbers of ejection portions, to the common pump are differentiated. This allows different flows to be produced in different ink discharge systems, thus generating desirable ink flows for individual ink supply systems.
