[0002] With the popularization and development of office automation equipment, laser printers have become an indispensable printing tool in offices and homes. As one of the core consumables of laser printers, the performance of toner cartridges directly affects print quality and user experience. The gear side cover of traditional CF226 / 258 series toner cartridges mostly adopts a split design, where the drum core mounting part and the gear side cover are two separate components. This design has certain limitations: the drum core mounting part is usually manufactured through an injection molding process, and dimensional errors are difficult to completely avoid during the production process. These errors can result in low assembly precision between the drum core mounting part and the gear side cover, which may cause interference during final installation in the printer, affecting the overall installation of the toner cartridge. Furthermore, the split structure makes the assembly process more complicated, requiring additional steps to ensure accurate fit between the components, which increases production costs and reduces production efficiency.

[0003] Therefore, it is imperative to redesign a CF226 / 258 series universal toner cartridge. Utility Model Content
