Abstract
A method of controlling a speed of a print medium through a printer includes the step of providing a print medium transport assembly with a range of print medium transport speeds between a minimum print medium transport speed and a maximum print medium transport speed. A print engine is provided with a print engine speed. The range of print medium transport speeds is divided into subranges of print medium transport speeds. A requested speed is provided to the print medium transport assembly which corresponds to the print engine speed. For each subrange, an acceleration profile control equation, a constant speed control equation, and a deceleration profile control equation is determined. The constant speed control equation is dependent upon the requested speed. One of the subranges of print medium transport speeds is identified which encompasses the requested speed. The print medium is transported through the print medium transport assembly according to the acceleration profile control equation, the constant speed control equation, and the deceleration profile control equation associated with the selected subrange.
