Printer With Mechanism For Controlling Recording Medium Tension

Abstract

A printer has a mechanism to counter change in the tension of the recording medium to convey the recording medium with more precision. Such printer has a media conveyance mechanism that conveys a recording medium; a printhead that prints on the medium; a media supply mechanism that supplies the medium to the media conveyance mechanism; a movable member that can move to compensate and thus counter internal tension changes in the recording medium resulting from operation of the media conveyance and supply mechanisms; a detector that detects the movement or position of the movable member; and a control unit that controls the media supply operation based on output from the detector so that the movable member is urged back to or maintained in a home position.
