Description

Technical Field

[0001] The utility model relates to the technical field of carbon powder cartridges, and in particular to a conductive edge cover structure applied to a Pantum 1100 carbon powder cartridge. Background Art

[0002] With the development of modern laser printing technology, the precision and stability requirements of printing equipment are increasing. In the design of the toner cartridge used in the existing Pantum 1100 series printers, the conductive side cover structure plays a key role. The inner side of the conductive side cover of the traditional structure is usually fixed with an OPC conductive iron column. The main function of the iron column is to apply a constant voltage to the drum core during the printing process to ensure the effective electrostatic imaging process. In addition, multiple conductive sheets are integrated on the outer surface of the side cover. These conductive sheets provide necessary charging support to each printing component through internal connection paths.

[0003] However, the existing conductive side cover structure has certain limitations. First, the fixed structure of the OPC conductive iron column leads to high assembly precision requirements and complex maintenance. At the same time, problems such as rust and poor contact may arise due to long-term use, which will directly affect the printing quality. Secondly, the multi-point connection structure of the outer conductive sheet increases the difficulty of production and assembly and the potential failure rate, and is easy to be damaged or cause unstable contact when replacing the toner cartridge.

[0004] In addition, the current method of installing the toner cartridge chip relies on the fixation of the adhesive film. Although it is simple and easy, the chip may fall off and the contact may fail under the high temperature working environment, which is not conducive to the reliable and stable operation of the toner cartridge.

[0005] In view of this, it is imperative to redesign a conductive side cover structure for use in the Pantum 1100 toner cartridge. Utility Model Content
