Drum core, that is, OPC is an abbreviation for organic photoconductor, also known as photosensitive drum; OPC drum is the use of OPC material coated on the surface of the conductive aluminum tube to form a photoelectric conversion device, which is characterized by the dark insulator , Can maintain a certain electrostatic charge, when a certain wavelength of light irradiation, into a conductor, the release of charge through the aluminum-based, the formation of electrostatic latent images, it is the core of the laser machine parts.
Drum other components introduced:
Drum drive gear: fixed at one end of the drum, the printer delivers power, drive the drum rotation, while driving the magnet roller rotation.
Drum reed reed: photosensitive drum surface exposure conduction charge, by reeling reed through the drum shaft pin (negative electrode) to release.
Drum baffle: drum support plate at one end.
Drum core prone to failure.
