Abstract
Abstract The present inventions are a reconditioned and resealed toner cartridge, the method of making the same, and a table saw used in this method. The reconditioned and resealed toner cartridge has a toner hopper, a new seal assembly and a mounting member. The new seal assembly comprises a gasket and a removable seal member which are secured between the toner hopper and the mounting member and seal the toner discharge opening. The method generally comprises the following steps: a) providing a used toner cartridge having a hopper and a mounting member which are attached by a used gasket, b) separating the toner hopper and mounting member from the used gasket, and c) securing a new seal assembly between said toner hopper and mounting member to seal the toner discharge opening. The table saw has a blade for cutting the outer edge of the used gasket, which separates the gasket from the toner hopper and mounting member. A cart is provided for aligning and carrying the toner cartridge passed the blade. A strip and a guide bar are also provided for ensuring one-directional movement of the cart. Finally, a vacuum system is provided for removing waist debris.
