PRINTER HAVING REGENERATIVE INTERMEDIARY DRIVE

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.
