The copier is now an essential office item, and its daily work can't be separated from its use. It is also good to know some copier principles in daily life and work. Copiers can be roughly divided into two types: analog copying and digital copying. The first digital copier was produced by Canon. This may not be known to many people. In the next few years, digital copiers are becoming more and more popular. So what is the difference between digital and analog copiers? What are the principles of these two copiers ?
First, analog copier
The principle of the analog copier is relatively simple, and the analog image is directly projected onto the photosensitive drum by light exposure, scanning, etc., and then through a series of steps to complete the copying.
However, the analog copying body is a more conventional copying machine and has its own shortcomings. Imaging by the principle of light reflection is likely to cause physical deviations, which will result in unclear graphics. A typical copier cannot be connected to a computer and cannot be copied multiple times, so the limitations are relatively large. But the price is relatively low, which is the choice of many small workplaces and families.
Second, digital copier
Digital copiers simply use photoelectric conversion to convert digital signals into image signals, and a series of steps to complete the copy. Digital copiers work the same way as both scanning and laser.
Third, the advantages and disadvantages of both
Digital copying allows you to scan the originals only once, so you can store the information in the machine, and you can make a lot of copies at any time. It is much simpler than the traditional simulator, reducing the number of work, and the problem of the card machine is rare.
Digital copiers can achieve paging, digital copiers electronic paging function is very powerful, open this function to copy more pages than the traditional analog copier plus pages.
In addition, the digital copier is also adapted to the requirements of continuous development, using advanced environmental protection technology, so that the copier can be automatically shut down, no waste toner, images can be rotated automatically, and so on.
Most digital copiers are equipped with a fax function, and can also transfer 3D manuscripts, which can be connected to a computer for network printing.
Judging from the difference between the two types of copiers , digital copiers have great advantages, which are unmatched by traditional analog copiers. They meet the needs of modernization. With the popularization of technology, digital copiers make office work easier and improve work efficiency.
