Abstract

A printer comprising: a sheet media transport mechanism for transporting sheet media past a printhead; a pick-up roller arranged to be rotated so as to contact and pick-up sheet media from a supply of sheet media and deliver the picked sheet media to the sheet media transport mechanism; and a gear assembly for communicating a driving force of a motor to the pick-up roller so as to rotate the pick-up roller, wherein a first gear of the gear assembly is arranged to disengage from a second gear of the gear assembly substantially at the point of delivery of a leading edge of the picked sheet media to the sheet media transport mechanism so as to cease communication of the driving force of the motor to the pick-up roller.
