Laser printer cartridge and Toner Cartridge structures

Most brands of laser printer cartridges and powder box structure is integrated, and this part of the problem of laser printer parts most likely to understand its structure is very good for our maintenance.

1, imaging features some of the components

Photosensitive drum: is made of aluminum tube coated with selenium, the selenium material for the insulator in the dark, exposed site of the conductor. When the laser beam emitted by them came to light, to light the information matrix of dots to form a electrostatic latent image.

Drum drive gear: with the photosensitive drum at one end is fixed by the printer delivered impetus for drum rotation, while driving transfer roller rotation.


Consumer Electric Drum reed: photosensitive drum surface exposure of the charge conduction from the power consumption by the photosensitive drum shaft spring pins (Consumer electrode) on the release.

Drum Flanges: the other side of the drum support plate.

Charge roller: In the wrapped conductive foam conductive shaft, the outermost membrane is the ionization. After conducting high-voltage charging stand with the conductive shaft contact discharge, from a sense of ionization membrane.

2, for some parts of the function of powder

Magnetic roller sleeve: each end equipped with a magnetic roller, its role is to control the photosensitive drum and the magnetic roller gap between the toner and imaging beating.

Wing Cores: Ymagnetic ferrite core is made of magnetic roller kit installed, it is fixed in the middle of aluminum cover is not rotation. When the rotating magnetic roller sleeve to carry toner to the permanent core of the "N" pole, make the magnetic toner to form toner fog (magnetic ear).

Developing bias Contact: The magnetic roller bias electrodes to provide imaging voltage.
Magnetic roller sleeve: Magnetic toner carrying roller is an important component, aluminum spray the surface of a graphite sleeve to increase the magnetic roller surface tension, and better carry toner, but also conducive to toner to the photosensitive drum surface adsorption (some machines type using a magnetic rubber).

Magnetic roller gear: with the photosensitive drum bite, to achieve with the Ministry of rotation.

Seal: Cartridge toner to facilitate the preservation, use the pull-out before sealing.

Bias electrodes: There are two roles, one through which imaging bias voltage applied to the magnetic roller, the second is a fixed permanent core of the "N" pole with the photosensitive drum in a tangential position.

Bunker covered: Refill mouth closures.

Felt Seal: Seal both ends of a magnetic roller to prevent toner spill along the magnetic roller at both ends, pollution printer.
Agitator gear: Rotary driven blender, stir and promote the toner.

Magnetic roller scraper: magnetic roller scraper is made of urea-formaldehyde resin, and use it to friction with the magnetic roller to ink evenly on the surface will not be added to the magnetic roller excess toner, and with other impurities segregation.

Toner warehouse: toner storage areas.

Drive gear: for the various components of power transmission bunker.
Bunker head: fixed bunker components, and imaging part of the connection.
