ABSTRACT:
In order to insert a replacement toner dam in an assembled toner cartridge, the opposing sides of the toner cartridge are caused to move towards each other so as to deform the cartridge and cause openings to appear at opposing ends thereof. A pair of web spring carriers are inserted into and through the openings so they exit from one opening. A new toner dam is inserted between web spring carriers at the portion thereof that exits from the opening. The web spring carriers are then withdrawn until the replacement toner dam is in a proper position. The dam is then held in position and the web spring carriers are freely withdrawn. This method thereby enables replacement of the toner dam without injury to seals at either end of the toner cartridge. Various non-adhesive bearing toner dam structures are shown, each of which has a flexible portion that engages a toner bottle flange and thereby enables a toner seal to be achieved without use of adhesive. Additional methods are described which require disassembly of a used toner cartridge and replacement of certain parts thereof.
