Description

Technical Field

[0001] The utility model relates to the technical field of printer accessory structures, in particular to a large-capacity toner cartridge and a printer thereof. Background Art

[0002] Toner cartridges, also known as photosensitive drums, are generally composed of a basic substrate made of aluminum and a photosensitive material coated on the substrate. In laser printers, most of the imaging components are concentrated in the toner cartridge, and the quality of printing is actually largely determined by the toner cartridge. The toner cartridge is equipped with structural components such as a toner storage bin, a magnetic roller, and a photosensitive roller. During the printing process, the photosensitive roller forms a latent image on its surface under the irradiation of the laser, and the toner is adsorbed on the latent image to form a real image, and finally the image is transferred to the paper to complete the printing. Due to the problems of small toner storage bin capacity and complicated replacement operation of existing toner cartridges, it brings many inconveniences in the process of frequent replacement of toner cartridges in the printer, affecting the working efficiency and convenience of the printer. Summary of the invention
