Removable toner cartridge guide and attachment of waste bin into a printer
View Patent ↗A toner cartridge having a more robust planar wing design having a uniform thickness along its extent so that the leading end thereof is no thinner than the trailing end thereof. Each planar wing is adapted to slidingly engage an associated guide groove formed in opposite sides of the printer. The uniform thickness along each wing's extent provides structural integrity and prevents the planar wing from flexing when the waste bin is being installed into the printer. The reduction in rearward sloping angle of the planar wing allows for easier installation and removal of the cartridge from the printer.
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;
said waste bin having a leading end sculpted to mate with the cartridge receiving cavity of a plurality of printer families;
a planar wing formed in each sidewall of said waste bin;
each planar wing formed on an outboard side of its associated sidewall;
each planar wing adapted to slidingly engage a guide groove formed in said printer;
each planar wing having a uniform thickness along its extent;
whereby each planar wing has structural integrity and does not flex when said waste bin cartridge is being installed into said printer; and
whereby said toner cartridge fits differing printer models distributed by differing manufacturers.
2. The toner cartridge of claim 1 , further comprising:
each planar wing having a leveled trailing end;
whereby said leveled end ensures optimal positioning of key components;
whereby said leveled end facilitates installation and removal of said toner cartridge; and
whereby said cartridge is easily loaded into the printer.
3. The toner cartridge of claim 1 , further comprising:
said trailing end of each planar wing being bifurcated into an upper trailing end and a lower trailing end;
said guide groove formed in said printer having an undercut area at its trailing end;
said lower trailing end of each planar wing fitting into said undercut area when said toner cartridge is fully received within said printer;
whereby said toner cartridge locks into place when said lower trailing end of each planar wing fits into said undercut area; and
whereby lifting a trailing end of said toner cartridge to remove said toner cartridge from said printer cavity retracts said lower trailing end from said undercut area.
4. The toner cartridge of claim 1 , further comprising:
said planar wing being discontinuous along its extent;
said planar wing having a leading part and a trailing part;
said guide groove formed in said printer having an undercut area at its trailing end;
said trailing end of each trailing part of each planar wing being bifurcated into an upper trailing end and a lower trailing end;
said lower trailing end of each trailing part of each planar wing fitting into said undercut area when said toner cartridge is fully received within said printer;
whereby materials are saved by eliminating a medial part of each planar wing without compromising the structural integrity of the connection between the toner cartridge and the printer;
whereby said toner cartridge locks into place when said lower trailing end of each trailing part of each planar wing fits into said undercut area; and
whereby lifting a trailing end of said toner cartridge to remove said toner cartridge from said printer cavity retracts said lower trailing end of each trailing part of each planar wing from said undercut area.
5. 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;
said waste bin having a leading end sculpted to mate with the cartridge receiving cavity of a plurality of printer families;
a plurality of axle members formed in each sidewall of said waste bin;
a wheel mounted to a free end of each axle member of said plurality of axle members;
each wheel respectively engaging a guide groove formed in said printer;
whereby said wheels collectively perform a guide function previously performed by planar wings; and
whereby said toner cartridge fits differing printer models distributed by differing manufacturers.
6. The toner cartridge of claim 5 , further comprising:
a flat plate formed in each sidewall of said waste bin in trailing relation to said plurality of wheel members;
a locating pin formed in each sidewall of said waste bin in trailing relation to said plurality of wheel members;
said guide groove formed in said printer having an undercut area at its trailing end;
said locating pin being positioned in said undercut area when said toner cartridge is fully received within said printer;
whereby said toner cartridge locks into place when each locating pin fits into its associated undercut area; and
whereby lifting a trailing end of said toner cartridge to remove said toner cartridge from said printer cavity retracts each locating pin from its associated undercut area.
