[0002] In modern office environments, printers are frequently used output devices, and printer toner cartridges, as an important component of printers, play a crucial role in storing toner and providing it for the printing process.

[0003] In ordinary printer toner cartridges, when waste toner accumulates to a certain amount in the waste toner compartment, it can negatively impact print quality. Excessive waste toner may spread inside the toner cartridge, contaminating critical components such as the developing roller, resulting in poor developing performance. Existing toner cartridge waste toner compartments are usually enclosed, making it difficult to collect and clean waste toner. When users find the waste toner compartment full, they need to remove the toner cartridge from the printer and then manually clean the waste toner through a complicated disassembly process. This cleaning method is not only cumbersome and time-consuming, but the waste toner can also easily scatter during the cleaning process, causing pollution to the office environment and potentially posing certain health risks. Inhaling waste toner may affect respiratory health. Frequent disassembly of the toner cartridge may also reduce the toner cartridge's sealing performance, affecting its normal service life and increasing operating costs. Utility Model Content
