ABSTRACT:
A toner cartridge splitter provides for the opening of the two major portions of a powdered toner cartridge, as used in various xerographic photocopy machines and printers. The device serves to separate the toner reservoir and mounting portions of a toner cartridge, thereby allowing the cartridge to be replenished with toner and resealed for further use, rather than merely being discarded after a single use. A toner cartridge is placed within the cartridge receptacle portion of the splitter, with the cartridge being immovably secured therein during the operation. A splitter blade is disposed coplanar with the seam of the cartridge between the two major components, and is driven between the two cartridge components to split them apart. A clearance notch may be provided in the blade to clear any protrusions in the cartridge rim which might otherwise block the penetration of the blade into the seam. The blade may be operated directly by a handle affixed thereto, or alternatively may be driven by an offset handle which provides greater mechanical advantage to a user of the device. While the present splitter is particularly adapted for use with HP Laserjet (.TM.) printer cartridges, it is readily adaptable for use in the opening of various other cartridges of similar construction but having different external configurations.
