LIQUID EJECTION APPARATUS

This abstract first appeared for US patent application 18885972 titled 'LIQUID EJECTION APPARATUS

Original Abstract Submitted

A controller of a liquid ejection apparatus controls an ejection inspection circuit to perform a first ejection inspection. After the first ejection inspection, the controller controls a driving element to perform a post-inspection driving operation including a plurality of types of driving operations. The plurality of types of driving operations have different driving frequencies for driving the driving element. After the post-inspection driving operation, the controller controls the ejection inspection circuit to perform a second ejection inspection. In a case where a first condition is satisfied regarding a relationship between a result of the first ejection inspection and a result of the second ejection inspection, the controller performs a first operation including the post-inspection driving operation after the second ejection inspection. In a case where the first condition is not satisfied, the controller performs a second operation different from the first operation after the second ejection inspection.
