Description

Technical Field

[0001] The utility model relates to the technical field of carbon powder cartridges, in particular to a TN350 / 360 / 580 universal carbon powder cartridge. Background Art

[0002] The traditional design of TN580 series toner cartridges in the current market has some inherent limitations, which are mainly reflected in the following aspects: First, the traditional toner cartridge has a high structural complexity and cumbersome assembly steps, which leads to increased production costs and affects the overall operating efficiency and stability. Secondly, the gear end and DR bracket are mostly separated, which is not only difficult to assemble, but also may become loose and worn over time, affecting the functional performance of the toner cartridge.

[0003] Regarding the conductive system design, the original toner cartridges mostly use an independent conductive end DR bracket combined with a conductive bracket. This separation design may lead to unstable charge conduction, indirectly affecting the uniform transfer of toner during the printing process, and limiting the further improvement of printing quality.

[0004] In addition, traditional toner cartridges generally use a long iron shaft and a large outer diameter developer roller design, which takes up a lot of space inside the toner cartridge, is not conducive to the layout optimization of compact printers, and increases energy consumption and reduces the efficiency of toner use. At the same time, after long-term use, the powder control performance of the developer roller may gradually decline, especially the powder knife has a simple structure and limited powder control accuracy, which cannot effectively guarantee the stability of long-term printing quality.

[0005] Therefore, it is imperative to redesign a TN350 / 360 / 580 universal toner cartridge. Utility Model Content

[0029] The conductive component 2 is provided with a first end cover 21 and a plurality of conductive posts 22. The first end cover 21 is provided with a conductive bracket positioning hole 211. The conductive bracket 61 is positioned on the conductive bracket positioning hole 211.
