ABSTRACT:
Methods of and apparatus for advancing a carriage utilize a displacement pump for displacing a selected quantity of fluid. The displacement pump is driven continuously by a motor to provide a series of fluid displacements which are accumulated in a hydraulic cylinder. A ram projecting from the hydraulic cylinder is coupled to the carriage and is advanced stepwise as the individual fluid displacements are accumulated in the hydraulic cylinder. The method and apparatus is especially useful for minimizing banding effects when advancing a carriage which supports a scanning device used in laser printers.
