Abstract

La présente invention concerne un système de distribution de toner pour une cartouche de toner sans agitation, qui comprend un ensemble palette à toner possédant une pluralité de racloirs. Un racloir principal racle le toner adhérant à des surfaces intérieures et dirige le toner depuis une première région du réservoir de toner vers l'ouverture dans une première partie de l'avant du logement. Un racloir secondaire positionné de façon adjacente au racloir principal racle le toner et le dirige depuis une seconde région du réservoir de toner vers la première région. Un racloir latéral racle le toner adhérant à des surfaces intérieures de parois latérales respectives du logement.
