Claim:
A toner cartridge adapted to fit within a toner cartridge-receiving cavity of a printer, comprising: a waste bin positioned at a leading end of said toner cartridge; a hopper connected to said waste bin at a trailing end of said waste bin; said waste bin and said hopper being fixedly interconnected to one another and being held against movement relative to one another when fully installed within said toner cartridge receiving cavity; and said waste bin having a leading end sculpted to mate with the cartridge receiving cavity of a plurality of printer families; a microswitch actuating tab formed in upstanding relation to a top wall of said waste bin; said microswitch actuating tab having a flat construction; a brace means formed at a base of said upstanding microswitch actuating tab to ensure that said microswitch actuating tab maintains said upstanding position; said microswitch actuating tab adapted to actuate a microswitch that is adapted to activate said printer when a door of said printer is fully closed; said microswitch actuating tab having a height sufficient to actuate said microswitch even when said door of said printer has worn latches, worn hinges, or both and therefore does not fully close; and said microswitch actuating tab extending above a highest point of said waste bin; whereby the microswitch actuating tab centers on a microswitch port to properly position the closing of the printer door even when the hinges and latches of said printer door are worn; and whereby said printer receives an actuating signal when said door of said printer is closed even if said printer has worn latches and hinges; whereby said toner cartridge fits differing printer models distributed by differing manufacturers.
