摘要： The invention provides a printing apparatus and a recovery method therefore which can minimize ink consumption in a recovery process for a print head of the apparatus. The invention has a control unit to cause a print head to eject ink from nozzles arrayed on the print head so as to recover ink ejecting function of the nozzles, and a specification unit to specify a set print mode selected from among a plurality of print modes. The print modes define number and position of nozzles in use for printing an image. The control unit executes a first preliminary ejection process before or after printing an image on a print medium. The first preliminary ejection process has selectively ejecting ink from both of the nozzles in use selected by the currently set print mode and the unused nozzles in the vicinity of the nozzles in use.

摘要： Wet wiping processing is performed on an ink ejection opening forming surface of a print head by use of a wiper. Then, as bubble removal processing, the print head is heated by use of either an electrothermal conversion element or a heat generating element located inside the print head, and then a control unit causes the print head to perform preliminary ejection K1 and preliminary ejection K2.

摘要： When the head temperature Tfinish, which is the head temperature at the time of completion of a preceding scan, is higher than the stable ejection temperature Tstable, the target temperature is made a temperature that is only a temperature value ΔT lower than the head temperature Tfinish. On the other hand, when Tfinish, the head temperature at the time of print completion, is lower than the stable ejection temperature Tstable, the target temperature is made a temperature that is only a temperature value ΔT higher than the head temperature Tfinish. Because of this it is possible to inhibit head temperature rise in the case where an image with a high print density is printed.

摘要翻译： 当作为前次扫描完成时的头部温度的头部温度T finish高于稳定喷射温度Tstable时，将目标温度设定为仅比头部低的温度值＆Dgr; T的温度 温度Tfinish。 另一方面，当印刷完成时的头部温度T finish低于稳定的喷射温度Tstable时，目标温度成为仅比头部温度T finish高的温度值＆Dgr; T的温度。 因此，可以在打印出高打印浓度的图像的情况下抑制头温升高。

摘要： An ink jet recording apparatus includes a recording head having a plurality of discharge ports for discharging ink supplied from an ink tank and a plurality of heating elements. The ink jet recording apparatus further includes a detection unit configured to detect a remaining amount of ink in the ink tank, and a preliminary discharge unit configured to discharge ink from the discharge ports, unrelated to recording, by applying energy to the heating elements for recovering the recording head. The ink jet recording apparatus performs control so that when the remaining amount of ink detected is less than a predesignated remaining amount of ink, energy applied to the heating elements per unit time by the preliminary discharge unit is smaller as compared with energy applied to the heating elements per unit time when the remaining amount of ink is more than or equal to the predesignated remaining amount of ink.

摘要： The order of the arrangement of ejection opening arrays of two types of ink overlapping in reciprocating scan is decided as follows. An ejection order is decided so that the case where the fixing areas of a main droplet and a satellite are different (dot area is increased) in the forward and backward scan first occurs. By this configuration, the area of the dot and the portion in which different colors are generated due to the difference in the overlapping order in the reciprocating scan can be reduced, compared with the case where the arrangement order is opposite to the above-described case. As a result, a difference in color between areas for which printing is completed by the reciprocating scanning is reduced and thus color unevenness of a printed image can be reduced.
