A scuff separating device capable of feeding difficult to separate sheets from the outside of a stack includes a feed belt or roller for contacting the outside sheet and feeding it off the stack. A retard roller is supported by a support arm pivoted about a pivot downstream, and rests on the feed belt or roller and prevents double feeds. A brake on the retard roller prevents rotation when more than one sheet is in the nip but permits rotation when one or no sheets are in the nip.

Scuff sheet separating device

A duplex document handler includes a supply tray on one side of a stationary exposure position, a simplex exit tray on the opposite side of the exposure position from the supply tray and a duplex exit tray above the supply tray. A turnover drum receives sheets from the supply tray and guides them past an exposure station and to the simplex exit tray or past the exposure station and through an inverting path to a reversing location, back to the exposure station and then back through the reversing location to the duplex exit tray.

Duplex document handler

In a document handling device two drive rollers are located on opposite sides of an exposure position. A drum is urged against the rollers and guides document sheets through the exposure position. Because the drum is not radially constrained except for the drive rollers, it is inexpensive to mount and manufacture.

Document sheet support mechanism

A scuff separating device capable of feeding document sheets from the bottom of a stack includes a feed belt below and contacting the bottom of the stack. A retard roller rests on the belt and prevents double feeds. The retard roller and belt both have high coefficients of friction. A brake on the retard roller prevents rotation when more than one sheet is in the nip but permits rotation when one or no sheets are in the nip.

Bottom scuff sheet separating device

A sheet separating device for a stack of sheets having feed and retard means forming a nip includes an insert held against the free end of the stack. The insert is moved into contact with the retard means to release its force on the last sheet, facilitating feeding of the last sheet.
