Abstract:
A method of controlling a speed of a print medium through a printer, said method comprising the steps 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;providing a print engine with a print engine speed;dividing said range of print medium transport speeds into a plurality of subranges of print medium transport speeds;providing a requested speed to said print medium transport assembly which corresponds to said print engine speed;determining for each said subrange an acceleration profile control equation, and a constant speed control equation, said constant speed control equation being dependent upon said requested speed;identifying one of said subranges of print medium transport speeds encompassing said requested speed; andtransporting the print medium through said print medium transport assembly according to said acceleration profile control equation, and said constant speed control equation, associated with said selected subrange.
