The sheet feeder bar stops disposed in a sheet feeding path of the auxiliary sheet pile and engageable by a leading region of the auxiliary sheet pile as viewed in sheet feeding direction. The sheet feeder further includes a holding device disposed substantially in a plane extending over the width of the sheets and movable under the leading region of the auxiliary pile, when the auxiliary pile support is removed, for permitting leading edges of the sheets in the auxiliary pile to be lowered a distance equal to less than the thickness of the removed auxiliary pile.
