AI Technical Summary
The existing paper guide roller structure of the developing cartridge results in high material costs, difficult assembly, and easy paper jams and mess on the cartridge surface during paper feeding.
The system employs a combination of an elastic guide plate and a tilting guide strip. The elastic guide plate is positioned at the edge of the cartridge opening, while the tilting guide strip is close to the photosensitive element. The printing medium is pressed inward by the elastic guide plate and pulled outward by the tilting guide strip, achieving stable transport.
It saves materials, is environmentally friendly, and ensures smooth paper feeding. The box surface is clean, preventing paper from loosening and clogging, and improving print quality.
