How does the Xerox® copier work?

and Xerox® copier, generally known as photocopy, basically works on the principles of static electricity. Electric charges can be either positive or negative, which is somewhat similar to the poles of magnets. The negative end of the magnet is immediately glued to the positive end of another magnet, but two negatives or positives repel each other. The same happens with negative and positive electric charges; The negatively charged comb attracts a positive charge of pepper flakes or a grain of salt. What we see as a document to be copied is actually considered anything but the black or white spaces for the Xerox® copier. When the document is placed on a glass tank for copying, there are a number of processes at once. This is where the science of copying. Fotoreceptor begins. The surface of this photoreceptor is made of special materials that can be negatively and positively charged in different areas simultaneously. The electric element known as the corona wire moves on the photoreceptor and gives CELike a latex balloon or a comb through the hair, a positive electrical charge, like wiped with a latex balloon. Once the entire surface of the photoreceptor is positively charged, intensely bright light moves on the surface of the original document to be copied.

This light emits photons that can easily penetrate the white parts of the document, but not the dark areas we consider to be an inscription. When photons hit the photoreceptor surface, these areas are electrically neutralized. However, the photoreceptor areas in the dark areas of the document remain positively charged. Basically, the Xerox® copier "The colors" Photoreceptor drum or a strap with static electricity and create a stain of positively charged images surrounded by negatively charged areas that remain white.

Once the document image is statically "painted" on a drum or belt, the Xerox® copy system covers the board negativelyAny black powder called toner . Wherever toner particles will find positively charged areas on the photoreceptor, they will stick to them like pepper flakes on a statically charged ridge. Toner will not stick to negatively charged areas of the belt or drum, so these areas will remain white.

After the toner particles have settled in positive areas, a second sheet of paper is introduced above the photoreceptor. The Coronian wire passes through this paper to give it a positive charge. Toner particles are transferred to charged paper and are now similar to the image of the original document. Toner is still VM released powder is a new copy pressed by a set of heated rollers known as fuser . The heat of the fixture melts the toner permanently. That is why some Xerox® copies, especially those made at the end of a long printing, may feel very warm to the touch.

After completing each start of copies, the corona corona is basically cleaned of the photoreceptor buBNU or belt by running a new positive charge. Because many photoreceptor drums have a smaller diameter than the length of the copy paper, it is not uncommon for copying process to be duplicated several times because the original document is scanned. The drum may have to be positively recharged to remove older information and receive new images a few lines at a time. All these actions are carefully synchronized to form a photocopy at a time when the lamp is scanned through the original time.
