Patent attributes
A universal adapter for a toner cartridge enables a single toner cartridge to be used with printers made by different manufacturers and differing printer models made by a common manufacturer. The toner cartridge includes a waste bin having a leading end that is sculpted to mate with the cartridge-receiving cavities of a large number of printers. Additional improvements include an improved planar having a common thickness along its extent, the elimination of a pivotal motion between the waste bin and the hopper, an enhanced interconnection between the waste bin and the hopper, improved ergonomics along a trailing edge of the waste bin to facilitate its handling, a structure that prevents mounting of a circuit board over a host circuit board, reduced friction media guide ribs, an improved circuit board mounting pad, and a microswitch actuating tab that functions even in a printer with worn hinges and latches.
