Abstract
In a calibration data input process, a carriageis moved toward an ink sensorto a prescribed position while the ink sensordetecting levels of reflected light. Then the amount of reflected light is read for over a range wider than the width of the carriageincluding a theoretical detecting position P. An actual detecting position Pis found based on the level of reflected light. The difference between the theoretical detecting position Pand the actual detecting position Pis calculated and is stored as the calibration value α in a first calibration data memory M. Accordingly, the actual detecting position Pis set as PThe calibration value α is used in a calibration process to calibrate the detecting position, so that the level of reflected light can be detected with accuracy.
