Patent attributes
An inkjet printer includes: a recording head which includes jet openings for jetting ink; a sensor for detecting a jet opening causing jetting failure among the jet openings; a sucking mechanism for sucking the ink from each jet opening; a comparing section for comparing number of the detected jet opening causing jetting failure with predetermined number; and a control section for performing a sucking process where the sucking mechanism performs a sucking operation, for performing an examination process to count the jet opening causing jetting failure by the detection of the sensor and by simulated jetting of each jet opening, for performing a comparing process where the comparing section performs a comparing operation after the examination process, and for re-performing the examination process without performing the sucking process when judged in the comparing process that the number of the jet opening causing jetting failure is more than the predetermined number.
