Description

Technical Field

[0001] The utility model relates to the technical field of printer toner cartridges, and more specifically to a printer toner cartridge capable of reducing residual toner in the cartridge. Background Art

[0002] A printer is one of the output devices of a computer, used to print the results of computer processing on related media. The toner cartridge is mainly used in laser printers and is filled with toner. It is a component in the laser printer used to store and supply toner. When the laser printer is working, the toner in the toner cartridge will be adsorbed onto the toner drum, and then transferred to the paper through static electricity to form text or images. The toner cartridge usually needs to be replaced regularly to ensure the printing quality and the normal operation of the printer.

[0003] When an existing toner cartridge is used, as the toner in the toner cartridge decreases, the toner remaining at the bottom of the toner cartridge cannot be adsorbed onto the toner drum. At this time, only toner can be added. Toner will still remain at the bottom of the toner cartridge after repeated use. After the toner cartridge is used and discarded, the residual toner inside will cause a waste of resources and is difficult to dump. The toner cartridge needs to be disassembled, and the toner in the toner cartridge is likely to cause environmental pollution during the disassembly. Utility Model Content
