A sheet feeder (14) for a print engine (10) includes a paper tray (30) which holds a stack of sheets (22) including a top sheet (20), and a pick-roller (42) which makes contact with the top sheet (20). The pick-roller (42) is rotatable about an axis. Also included is a driver (44), which upon forward energizing, rotationally drives the pick-roller (42) about the axis in a forward direction to advance the top sheet (20) to sheet advancing means (34) that pass the top sheet (20) along through the print engine (10). A drive controller (50) controls the driver (44). The drive controller (50) causes the pick-roller (42) to be released for free-wheeling after advancing the top sheet (20) to the sheet advancing means (34).
