Removable toner cartridge activating apparatus to detect door closure
View Patent ↗A microswitch actuating tab for a toner cartridge to activate the printer when the printer door is fully closed. The microswitch-actuating tab actuates the printer microswitch even when the door of the printer has worn latches or hinges and does not fully close. The microswitch has a uniform thickness and is taller than conventional actuating tabs. It therefore provides a more positive engagement of the microswitch. The actuating tab is structurally stronger than prior art microswitch actuating tabs and has a greater height so that it remains effective even when the hinges and latches of the printer door are worn, loose, or on otherwise poor condition. The printer therefore receives an activating signal when the door of the printer is closed even if the printer has worn latches and hinges.
1. 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.
2. 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 top section, a mid-section, and a bottom section; and
said top section widening from top to bottom, said bottom section narrowing from top to bottom, and said mid-section being wider than said top section and said bottom section;
whereby the narrow top edge of said microswitch actuating tab facilitates its entry into a narrow opening formed in the bottom edge of said printer door;
whereby said widened middle section helps said microswitch actuating tab to positively engage said narrow opening;
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.
