Patent

CA 2265750

Electrostatic cartridges (10) having a gear housing assembly which blocks access to a toner fill hole (22) and which includes an interior gear housing component (18a) integral with a cartridge base (14) are remanufactured by severing the interior gear housing component (18a) and then reattaching it to the cartridge base (14) through the exterior gear housing component (18b). The one-piece interior gear housing assembly (18a) is severed preferably at a 5 degree angle relative to the cartridge base (14) providing unobstructed access to the original toner fill hole (22), thereby ensuring that the attachment bosses (30) on the cartridge base (14) are not damaged to an extent that would defeat their coupling function. Paired reattachment holes (40a, 40b and 42a, 42b) are formed in the interior and exterior gear housing components (18a and 18b) to allow them to be reattached to one another via screw (44) and nut (46) assemblies extending therethrough, where they may then be connected to the cartridge base (14) by screws (20).

Il est possible de remanufacturer des cartouches électrostatographiques (10) comportant un ensemble boîtier, qui bloque l'accès à un orifice de remplissage (22) de toner et qui comprend un composant boîtier d'engrenage intérieur (18a) formé en monobloc avec une base de cartouche (14), en séparant le composant boîtier d'engrenage intérieur (18a) et en le refixant sur la base (14) par l'intermédiaire du composant boîtier d'engrenage extérieur (18b). L'ensemble boîtier d'engrenage intérieur (18a) monobloc est séparé de préférence selon un angle de 5 degrés par rapport à la base de la cartouche (14), ce qui permet d'accéder librement au trou de remplissage (22) de toner d'origine. Ceci assure que les bossages de fixation (30) de la base (14) ne sont pas trop endommagés pour gêner leur fonction de couplage. Les paires de trous de fixation (40a, 40b et 42a, 42b) sont formées à l'intérieur et à l'extérieur des composants (18a, 18b) du boîtier, ce qui permet de les refixer l'une à l'autre par des ensembles vis (44) et écrous (46) les traversant, et ainsi de les relier à la base (14) de la cartouche par des vis (20).
