Simple understanding: 1. Analog photocopier: It is the original photocopier, and it is a copy of each scan. The printing function could not be realized, and some of them were originally based on the principle of a canua-style camera, and the scanning was carried out.
2. Digital copier: multiple copies can be completed by scanning once, and the functions of printing, scanning and faxing can be realized. CCD is used for scanning, laser units (PH, LED, etc.) are used for development, and the speed and quality of copies are higher than those of analog copiers.
Portable copier: A portable photocopier, which is relatively small, is the kind of A4 side side.
Specifically, you can also refer to the principle of the photocopier, there are books on this subject.
It is recommended that you buy an all-in-one computer (MFP) for more than 2000. It can be printed, scanned, and faxed, but it is an A4 side. If you want which brand, you can look it up on the Internet too much.

The image of the analog photocopier is enlarged and reduced by adjusting the lens, and the digital machine converts the optical signal into a numeric number, and the image is carried out through the digits.
A portable photocopier is a desktop copier, which is only said to be convenient to use, but it is slow and expensive to use.

You can look up the meaning of each word in the dictionary, so I won't copy and paste, I think consulting the Oxford Advanced English-Chinese Dictionary and comparing the English explanations of these words will help you understand better.
Briefly my understanding.
view n.Refers to a landscape within the field of vision seen from a distance or from a window, meaning "scene", "scenery".
scenery is smaller in scope than scene, just "scenery".
sight refers to "scene" and "spectacle", emphasizing that seeing things that are within the field of vision or within sight seems to have no meaning of scenery in both noun form and verb form. Specifications It means so.

The preceding words are a bit more written.
I used to think that when I was writing a book, I would try to use that kind of language in lyrical prose.
But I also think that the meaning of the before and after is out of the way.

How photocopiers work.
1. The electrostatic photocopier directly projects the optical simulation image of the original through the optical system to the charged photoreceptor drum through exposure and scanning to generate an electrostatic latent image, and then completes the copying process through the steps of development, transfer and fixing. >>>More
Samsung 555p. With laser printing, copying, faxing, scanning. It's just expensive.
First of all, check whether there is a problem with the toner, but the customer has been cooperating with us, and the powder has always been the original powder provided by our company, so this possibility can be ruled out, and then the only way to check is that the fuser roller is broken, and after checking, the fuser roller is indeed sticky with toner. So the only way to do this is to remove the fuser roller and clean it. When taking the fuser roller, the back cover should be removed first, then the side door should be opened, the screws at both ends of the fuser roller should be removed, and then the three sets of connected lines behind the fuser roller should be taken out. >>>More
