Universal toner cartridge circuit board mounting pads
View Patent ↗An improved circuit board mounting system for use with a toner cartridge. The first circuit board mounting pad holds a circuit board with large electrical contacts that mate with printer-mounted contacts in numerous positions. A second circuit board mounting pad is positioned on a vertical wall of the waste bin and holds a circuit board with electrical contacts that mates with printers that mate with electrical contact pads positioned near the front left edge of the waste bin. The second circuit board mounting pad also accommodates a larger circuit board that supports larger components or a greater number of components.
1. A toner cartridge adapted to fit within a toner cartridge-receiving cavity of a printer, comprising:
a waste bin;
a hopper connected to said waste bin;
a first circuit board mounting pad adapted to receive a circuit board that mates with a first group of printers; and
a second circuit board mounting pad adapted to receive a circuit board that mates with a second group of printers.
2. The toner cartridge of claim 1 wherein at least one circuit board mounting pad is formed in a substantially horizontal wall of said waste bin.
3. The toner cartridge of claim 2 , further comprising:
a first connection pad and a second connection pad mounted on said horizontally-mounted circuit board;
said first connection pad and said second connection pad adapted to make electrical contact with upper door-mounted electrical contacts that are provided on printers of a particular family of printers.
4. The toner cartridge of claim 1 wherein at least one circuit board mounting pad is formed in a substantially vertical wall of said waste bin.
5. The toner cartridge of claim 4 , further comprising:
a first connection pad and a second connection pad mounted on said vertically-mounted circuit board;
said first connection pad and said second connection pad adapted to make electrical contact with electrical contacts that are provided on printers that belong to a plurality of families of printers.
6. The toner cartridge of claim 1 wherein said first circuit board mounting pad is positioned on a vertical wall of said waste bin;
said vertical wall being disposed in trailing relation to the leading end of said waste bin; and
said first circuit board mounting pad adapted to mate with printers having front contact pins that mate with circuit boards positioned on vertical mounting pads.
7. The toner cartridge of claim 1 , wherein:
a second circuit board mounting pad is formed in a substantially horizontal wall of said waste bin;
said second circuit board mounting pad having a size sufficient to hold a large circuit board;
said large circuit board having a size sufficient to receive first printer door contacts in a first position and second printer door contacts in a second position;
whereby said first printer door contacts are adapted to mate with contact pins that belong to a first group of printers;
whereby said second printer door contacts are adapted to mate with contact pins that belong to a second group of printers; and
whereby said large circuit board mounting pad enables said toner cartridge to universally accept a plurality of printers having printer door contacts that are adapted to engage circuit boards that are horizontally mounted.
