Abstract

A toner cartridge prevents piggybacking of an unauthorized circuit board over an authorized circuit board. The body of the cartridge includes a flat mounting surface adapted to receive a first circuit board formed in a vertical wall of the waste bin. An upper blocking member extends from a point just above the flat mounting surface to a lower surface of the planar wing. An optional lower blocking member extends from a point just below the flat mounting surface to a preselected point at a still further lower elevation. The upper and lower blocking members obstruct the placing of an unauthorized circuit board over an authorized circuit board.
