Abstract
Replacement of a recording head on a recording apparatus is detected on the basis of a serial number allocated to each recording head. The recording head also carries head characteristic information such as color information, shading information and so forth. When the recording head is replaced with a new one, the head characteristic information of the newly mounted recording head is automatically stored, so that head driving conditions are automatically determined to optimize the recording conditions without requiring any manual adjustment. Recovery operation is automatically executed when replacement of the recording head is detected, so that required recording conditions are recovered without manual instructions.
