Ink jet printing apparatus and ink jet printing method
Abstract:
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.
