发明名称 INK JET PRINTING APPARATUS AND INK JET PRINTING METHOD
摘要 An ink jet printing apparatus and an ink jet printing method are provided which can perform ink ejection performance recovery operations on a print head at optimal timings while at the same time reducing a volume of ink discarded by the recovery operations. Thirty days after a previous recovery operation, a suction-based recovery operation is performed on the print head prior to the printing operation that forms an image on a print medium. The recovery operation is performed under the condition that a temperature increase of the print head caused by a preliminary ejection of the print head is not more than a predetermined value.
