Description

Technical Field

[0001] The utility model relates to the field of printing consumables, in particular to a powder box with an enlarged powder bin and a waste powder bin. Background Art

[0002] Traditional powder cartridges have a small powder storage space and can only hold a small amount of toner. Users need to frequently replace the powder cartridge or add powder to the cartridge, resulting in a poor user experience.

[0003] There is also a toner cartridge that increases the toner capacity by adding a toner refill bin. However, the waste toner bin in the toner cartridge is not enlarged, so that the waste toner bin cannot accommodate the increased toner. Therefore, when the waste toner in the waste toner bin reaches a certain amount, printing cannot continue. Therefore, only increasing the toner bin capacity does not necessarily increase the number of printed pages. Utility Model Content
