Abstract:
1. A sheet feeding apparatus, comprising: a supply tray for holding media sheets; an output tray; a pickup unit configured to pull a media sheet from the supply tray and feed the media sheet to a scanning region in a media path; opposing de-skew rollers positioned at a beginning of the media path and configured to de-skew the media sheet when the media sheet enters the media path; opposing pre-scan rollers positioned along said media path upstream from the scanning region; opposing post-scan rollers positioned along said media path downstream from the scanning region; opposing output rollers positioned at an end of the media path; and a switch-back path extending from the output rollers to the de-skew rollers and configured to guide the media sheet back into the media path, wherein the pickup unit, the de-skew rollers, the pre-scan rollers, the post-scan rollers, and the output rollers cooperate to provide, separately, a high throughput mode, a delay mode, and a duplex mode of the sheet feeding apparatus, wherein, in the high throughput mode, the pre-scan rollers contact a trailing end of a previous media sheet as the de-skew rollers contact a leading end of a subsequent media sheet.
