Abstract:
1. A method for adjusting drive characteristics of a scanner driver of a galvanometric scanner, comprising: determining optimized data formed from combinations of optimal values of circuit constants of the scanner driver that drives the galvanometric scanner in accordance with a plurality of drive modes of the galvanometric scanner; storing and holding the optimized data, which correspond to the respective drive modes, in a scanner-side storage section in the galvanometric scanner or a driver-side storage section in the scanner driver; providing an external signal that specifies one of the drive modes to the scanner driver, whereby the optimized data that corresponds to the specified drive mode are outputted from the scanner-side storage section or the driver-side storage section; and, in the scanner driver, setting the circuit constants of the scanner driver or changing the previously set circuit constants of the scanner driver in accordance with the outputted optimized data.
