A sheet accumulating apparatus accumulates inputted sheets into a stack registered on all sides, wherein the sheets are controlled with minimum contact by components of the apparatus to minimize or eliminate smudging or marking of the sheets. The apparatus can be selectively adjusted to effect over-accumulation or under-accumulation, and can be adjusted to accommodate different sheet sizes. The apparatus comprises an accumulation section defining a sheet feed plane therethrough. An upper ramp is disposed upstream from the accumulation section and is movable into and out of the sheet feed plane. An upper retaining member is linked to the upper ramp and is movable into and out of the sheet feed plane in alternating relation to the upper ramp. A lower ramp is disposed below the upper ramp and is movable into and out of the sheet feed plane in alternating relation to the upper ramp. A lower retaining member is linked to the lower ramp and movable into and out of the sheet feed plane in alternating relation to the upper ramp.
