ABSTRACT:
An auto-compensating mechanism lifter comprises an auto-compensating mechanism (ACM) and a lifter for moving a sheet of print media from a media feed tray in a document feeding device for printer, multifunction device or similar device. The auto-compensating mechanism includes a housing having a pick tire and drive train therein. The housing is pivotally mounted for movement in a first direction and a second direction. The pick tire is mounted to the housing and operably engaging the drive train and the print media. The auto-compensating lifter comprises a spring clutch coupling a drive shaft and the housing for rotating the ACM onto or away from the print media in the media feed tray depending upon the direction of rotation of the drive shaft. The pick roller is mounted distal to the pivotal connection of the auto-compensating mechanism to the drive shaft.
