Patent attributes
An imaging apparatus (30) for thermally recording images on an imaging media (44) including a printhead (32) having an array of individually energizeable heating elements (42), a rotatable drum (34) for conveying imaging media (44) past the array of heating elements (42), and an anchor element (36) moveable within a range of positions. A biasing mechanism (38) is positioned between printhead (32) and anchor element (36) and is configured to provide a biasing force to hold at least a portion of the array of heating elements (42) against rotatable drum (34), wherein a magnitude of the biasing force is based on the position of anchor element (36). An actuator system (40) is configured to adjust the position of the anchor element (36) within the range of positions so as to adjust the magnitude of the biasing force over a range of values.
