[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This toner cartridge, which reduces toner residue, uses a vibrating motor to drive a vibrating plate, further promoting toner flow and effectively reducing toner residue. This improves toner utilization, lowers printing costs, and because the vibrating motor is elastically connected to the upper guide plate, the guide plate vibrates along with the vibrating motor, causing the toner in the toner container to flow downwards from the guide plate, reducing toner residue. Simultaneously, under gravity, the toner naturally flows to the outlet at the guide plate and is discharged downwards, further reducing toner residue. The operation of the vibrating motor is controlled by a control module. During normal use, natural gravity flow is allowed. After use, the control module commands the vibrating motor to vibrate, causing the vibrating plate and guide plate to vibrate together, further improving toner flow and reducing residue.

[0017] 2. This toner cartridge, which reduces toner residue, is connected and fixed to the drive motor inside the connecting cover on both sides of the cartridge body via a coupling that passes through the connecting hole on the cartridge body. The operation of the drive motor causes the two sets of counter-rotating rollers to rotate inwards and in opposite directions, causing the toner flowing down from the guide plate in the middle of the upper toner receiving cavity to gather inwards and fall into the middle of the lower vibrating plate, allowing the vibrating plate to better flow toner. The toner inside the cartridge body can be replenished by rotating the sealing cover on the replenishment port and using the replenishment port. Attached Figure Description
