As far as the PO canon copiers are concerned, there is no doubt at all that they are one of the most commonly used machines at present and one will definitely find that the whole market is filled with these machines. It is costly and hence all the people cannot afford them in their house and hence they are ready to pay the rent for these copiers and undoubtedly one will definitely find that paying for per copy is quite cheaper than to buy these photocopiers.

Have you heard about the term Xerox? Well, you must have heard and by Xerox, we generally mean copy of the pages. However, does it mean the same?

That is why we also call this machine Xerox as well. The mechanism of this machine is based on five steps, which are the charging, exposure, developing, transfer, as well as fusion. Undoubtedly, these are the basic step, that determines the running of these machines and it all starts with the charging.

It consists of a cylindrical drum and the paper is rolled over this cylindrical drum. It is electro statically charged and there is no doubt at all that the photoelectric effect is also being used in this process. There is no doubt at all that these drums become electrically conductive when they are exposed to light. One must have seen the yellow light glowing inside the photocopier machine and the Canon Copiers are definitely two of the very common copier machines that are definitely very costly. However, they are good. The step of exposure uses the photoelectric effect. The black portion is negatively charged and hence it forms an image on the drum and then on the page.

The toner is positively charged and when the light falls, then it melts down and is filled on the black portion of the paper and thus we get the required print out of the paper. The Ricoh copiers are also quite costly as well.
