ABSTRACT:
In consideration of a coupling condition between a carriage having a functional element, such as a printing head, and a carrier for moving the carriage, position control therefor is performed appropriately for improving printed image quality and satisfactorily obtaining the function of the functional element. With respect to a scanning body as the carrier, a carriage for black ink and a carriage for color ink are selectively coupled by a gripper. Sensor blocking plates are respectively provided on the scanning body and the carriages. On the basis of a timing, at which the sensor blocking plate blocks an optical path of a home position sensor provided at a predetermined position of a main body of an apparatus, a correction amount for position control corresponding to a coupling play of the carriage relative to the carrier is derived.
