Adjusting method for use in recording apparatus, recording apparatus

A recording apparatus comprising:

• a conveyance mechanism for moving a recording medium in a first direction relative to recording heads;
• a plurality of head units arranged in the first direction;
• a plurality of recording heads, which are arranged in each of the plurality of head units and arranged in a second direction crossing the first direction so that recordable regions of the recording heads partially overlap or become continuous, for making desired image recording on the recording medium by combining a nearly line recording operation, which is performed by the plurality of recording heads in the second direction, and a moving operation of the recording medium, which is performed by the conveyance mechanism in the first direction;
• first controlling means for controlling at least one of positions and inclinations of the plurality of recording heads in each of the plurality of head units, and one recording timing of each of the recording heads;
• and
• second controlling means for controlling at least one of positions and inclinations of the plurality of head units, and a recording timing of each of the head units;
• wherein:
• said first controlling means has a control function to implement at least one of a first adjustment condition under which a center of a predetermined recording pattern recorded by each of the plurality of recording heads within the head unit is placed almost in a same linear line in the second direction, and a second adjustment condition under which boundaries of the recording patterns recorded by the plurality of recording heads within the head unit become almost continuous;
• and
• said second controlling means has a control function to implement at least one of a third adjustment condition under which centers of the recording patterns recorded by the plurality of recording heads within the respective head units, which have a same recordable region, almost match in the second direction, and a fourth adjustment condition under which centers of the plurality of recording patterns, which are recorded by all the recording heads within the plurality of head units, for the respective head units, in the first direction almost match in the first direction.
