Copiers are common office equipment. With the development of copiers, there are more and more types. Before you choose, you must understand these classifications in detail to choose the products that suit you. So what is a copier? What are the classifications of copiers? Let's take a look at the decoration home decoration network Xiaobian.
What is a copier?
What we usually call a copying machine is an electrostatic copying machine, which is a device that uses electrostatic technology to copy papers. A copying machine is a device that obtains copies that are doubled, enlarged, or reduced from an original that is written, drawn, or printed. Copiers are fast and easy to copy, and the main difference from traditional typeface printing, stencil mime printing, offset printing, etc. is that they can obtain copies directly from the original without intermediate means such as other plate making.
What are the classifications of copiers?
Classification of copiers 1. Divided from the working principle of copiers, they can be mainly divided into analog copiers, digital copiers and digital copiers.
(1) Analog copier: The time for analog copier production and application has been relatively long. The principle is mentioned in the junior high school physics textbook. Simply speaking, the optical analog image of the original is directly projected through the optical system through exposure and scanning. An electrostatic latent image is generated on the charged photosensitive drum, and then subjected to development, transfer, fixing, and the like to complete the copying.
(2) Digital copier: Digital copier is imaged by laser scanning and digital image processing technology. It is a copying device, and can be used as an input/output device in conjunction with computers and other office automation (OA) devices, or become a network. Terminal. Therefore, with the advent of the human society information age, digital technology will be more widely used in all aspects of human society production and life, digital copiers will also become the leading products of copying equipment. Digital copiers will become a good helper for office automation with its high productivity, excellent image quality, diversified functions (copy, fax, network printing, etc.), high reliability and scalable design system.
(3) Digital copier: Digital copier is a qualitative improvement compared to analog copier. In fact, digital copier is a combination of a scanner and a laser printer. It is first produced by exposure and scanning through a CCD (Charge Coupled Device) sensor. The optical analog image signal of the original is photoelectrically converted, and then the image signal processed by the digital technology is input to the laser modulator, and the modulated laser beam scans the charged photosensitive drum to generate a somewhat electrostatic potential on the photosensitive drum. Image, then through the steps of development, transfer, fixing, etc. to complete the copying process. But in fact, there are a lot of cheap digital copiers that print through inkjet.
The classification of the copying machine 2, which is divided into the use of the copying machine, can be divided into a household type copying machine, an office type copying machine, a portable copying machine, and an engineering drawing copying machine.
(1) Household type copiers: Household type copiers are relatively inexpensive, generally have both scanners and printer functions, and printing methods are mainly inkjet printing.
(2) Office type copier: Office type copier is our most common copier, basically based on A3 format products. The main purpose is to copy all kinds of documents in the daily office. From a technical point of view, analog products and digital products currently account for half of each.
(3) Portable Copier: The characteristics of the portable copier are definitely small. Its maximum format is generally only A4, and the weight is light. The main products are mainly analog machines.
(4) Engineering drawings Copier: Engineering drawings Copiers are characterized by a large format, which can generally reach A0 format, which is used to copy large-scale engineering drawings. It is also divided into analog engineering drawing copiers and digital engineering drawings copiers according to technical principles. Although it is still mostly analog products, it is transitioning to digital products at a relatively fast speed.
The above is what Xiaobian brought to you. What is a copy machine? What are the classifications of copiers? I believe that everyone has a basic understanding of the copier after reading this article.
