Patent ID: 7355613

Claim:
An imaging apparatus for thermally recording images on an imaging media, the imaging apparatus comprising: a printhead having an array of individually energizeable heating elements; a rotatable drum for conveying an imaging media past the array of heating elements, the imaging media being one of a plurality of widths; an anchor element moveable within a range of positions; a biasing mechanism positioned between the printhead and the anchor element and configured to provide a biasing force to hold at least a portion of the array of heating elements against the rotatable drum, wherein a magnitude of the biasing force is based on the position of the anchor element; and an actuator system configured to adjust the position of the anchor element within the range of positions to adjust the magnitude of the biasing force over a range of values so as to maintain a ratio of the magnitude of the biasing force to the width of the imaging media at a same desired value for all widths of the plurality of widths of imaging media.
