Abstract:
A method for position calibration of a spot of an optical sensor may include providing a position calibration patch on a sheet at a predetermined position, along a scan path of the spot across the sheet, the patch comprising at least two adjacent blocks of different colors. The method may also include obtaining a single sample of the position calibration patch using the optical sensor. The method may further include determining from the single sample the position of the spot of the sensor with respect to the position calibration patch.
