Abstract
An encoder signal compensation method and the apparatus thereof are described. The encoder signal compensation method includes the following steps. First, encoder output signals are read to calculate compensation parameters. Subsequent encoder output signals are compensated according to the calculated compensation parameters and the compensated encoder output signals are utilized to control a printing process. The encoder signal compensation method is effective in eliminating width errors and phase errors of the encoder output signals. Another embodiment of the invention is to provide a printing apparatus utilizing the encoder signal compensation method to reduce high frequency banding, effectively improving the printing quality.
