HP RC4-7682-000CN is the left cover for a 550-sheet paper feeder. It is a replacement cover component for the feeder, rather than the feeder assembly itself. Its defined position helps identify it among the separate covers used around the paper feed unit.
The part is listed for the HP Color LaserJet Managed E65160dn printer. The parts list separates it from the feeder’s rear cover RC4-7683-000CN and right lower cover RC4-7684-000CN, so this item is specifically the left-side cover. It is suited to a repair or parts replacement where that identified cover is needed.
