摘要： A printer includes: a media tray (10); a picker (15); a media guide (16) for guiding the media sheets around a media feed path towards a print zone (22); a main drive roller assembly (23) positioned upstream of the print zone; and an intermediary drive roller assembly (40,42,44) positioned between the picker and the main drive roller assembly. The intermediary drive roller assembly includes: an intermediary idler roller (42) mounted on an intermediary idler shaft; and an intermediary drive roller (44) having a gripping surface engaged with the intermediary idler roller. An intermediary drive shaft is pivotally connected to a support shaft via a swing arm (40, 72), such that the intermediary drive shaft is arcuately moveable relative to the intermediary idler shaft to provide a variable distance therebetween.

摘要： A print module includes: a cradle defining a longitudinal cavity; an elongate printhead received in the longitudinal cavity, the printhead having a row of printhead contacts; a PCB slidably movable relative to the cradle along a first axis perpendicular to a longitudinal axis of the printhead; and an actuator handle. The actuator handle is configured for reciprocally lowering and raising the PCB and urging the PCB contacts into engagement with the printhead contacts, thereby forming electrical connections between the PCB and the printhead. The PCB electrical contacts are urged along a second axis perpendicular to the first axis and the longitudinal axis of the printhead.
