ABSTRACT:
An ink jet injection system performs detecting an ink injection condition by ejecting ink droplets so as to form a detecting pattern on a recording medium. When the detecting pattern is formed, the ink droplets are ejected at almost the same position in the state in which the transportation of the recording medium is stopped or a feeding speed of the recording medium is set slower than that during a normal printing operation.
