AI Technical Summary

Problems solved by technology

Due to the many internal components of the toner cartridge, the replacement cost is high, and if the user fills the toner cartridge by himself, it is easy to cause powder jams or leakage during printing due to improper operation, which will affect the printing effect or pollute the printed image

However, in the existing split toner cartridge structure, the toner bin and the developing roller are usually separated into one component. When the toner in the toner bin is used up, the toner bin and the developing roller need to be replaced at the same time, and the replacement cost is relatively high.
