Electronic beam imaging digital printing technology for printing technology

Electron beam imaging digital printing, also known as ion imaging digital printing, creates a latent image by directing the flow of charge. This process is similar to electrophotographic printing, except that electrophotographic printing charges the photosensitive drum first and then The latent image is generated by exposure; the electrostatic image printed by electron beam imaging is directly formed by the output ion beam or electron beam signal.

Electrostatic image drums printed by ion beam or electron beam imaging are generally made of a more rugged, more durable insulating material to receive the electron beam charge.

In the operation of the electron beam imaging digital printing system, electron beams are first generated by the imaging cartridge. The electron beams are arranged in an electron beam array through a guide cylinder connected to the imaging cartridge. The electron beam array is guided to an insulating surface that can temporarily absorb negative charges. When the drum rotates, an electron latent image is formed on the insulating surface due to the opening and closing of the electron beam, and when the drum is rotated to the position where the toner cartridge is located, the electron latent image will adsorb the positively charged toner particles and have adsorbed thereon. The insulating surface of the toner particles continues to rotate to the transfer roller. When the paper passes through the combination of the transfer roller and the insulating roller, the paper is pressed by the transfer roller; under this pressure, the insulating surface and the paper surface It is in close contact and under great pressure, so that the electronic latent image-absorbed toner particles are transferred to the paper. Considering that the electron latent image-absorbed toner particles cannot be completely transferred to the surface of the paper, they are transferred. A scraper is installed behind the roller to scrape off those toner particles that have not been transferred. After the above process is completed, the toner particles that have not been transferred to the paper surface are Out, but also with an electronic insulating surface may, for erasing roller erasing remaining need to use an electronic down, the next step to facilitate the transfer and imaging.
