Beginners must see: Terms Xiangjie copiers – copiers – Office Supplies Industry
Duplicator Is a highly professional Office Equipment Composite machine is coming from the copier development, from the previous analog copy to the back of digital copiers, digital copiers and then continued on the basis of functional integration, the formation of the digital composite machine in daily use has been broad user acceptance, in fact, if you want a better understanding of a product, I think from the copier before beginning to understand a basic accessory, so the composite machine can have a deeper understanding.
1, NP electrostatic copying method Canon
NP invented method is a new electrostatic copying method, which is different from the traditional electrostatic copying method Carlson, Carlson electrostatic copying method which is the improvement and development. NP is the basic process of electrostatic copying method mainly by the consumer before the electricity / before exposure, a charge (main charge), the second charge / image exposure, full exposure, development, transfer, separation, fuser, drum cleaning 9 basic steps.
2, charge Charge is to make the photosensitive drum in the dark, and impose a polarity of the electric field in a make uniform areas on the surface of a certain polarity and the number of electrostatic charge, which has a surface potential of the process that the actual photosensitive drum is the process of sensitization to the original photosensitive drum do not have good photosensitivity. Photosensitive drum charging only for receiving image information prepared for the original image information is not dependent on pre-process, but it is in the photosensitive drum electrostatic latent image formed on the surface the premise and foundation.
3, one-component copiers That uses Canon's patented method of copying mechanism NP copiers. As the NP copy method using CdS photosensitive material, the toner is a single component, unlike the Carlson method copier toner needs the addition of iron powder as a carrier.
4, snapshot Snapshot copy paper is to unstable, can erase the toner image fixing process, through transfer, separation transferred to the reproduction of red dye on image, not blending together with the copy paper, which When the toner image extremely erased, so subject to solidify its snapshot device, to form the final copy products. Electrostatic copiers now use more heat and pressure combination of hot melt toner to the fuser. Snapshot device heating temperature and time, the size of Phoenix and the pressure of pressure, strong adhesion to the toner images have a certain degree of influence. Among them, the heating temperature control, image snapshot quality is the key to good or bad.
5, snapshot method Use some method to develop the image fixed in the copy media (eg paper) on the process is called snapshot. Electrostatic copier fuser hot version of snapshot mode, thermal radiation fuser, fuser hot roll, cold and chemical melting snapshot snapshot so.
6, separation
The aforementioned transfer process, the copy paper as electrostatic adsorption, the photosensitive drum tightly attached, the separation is to close to the surface of the photosensitive drum copy paper peeling from the photosensitive drum (separation) down process, electrostatic copier in general with separate corona (AC and DC) and the separation claw or split with other parties not to carry out the separation of paper and imaging drum.
