How can I get a copy?
When making a copy, place a piece of paper or a book on the glass of the copier and push the switch button. After that, an object emitting a very bright light moves slowly under the glass.
That light is reading what is written on the paper. The machine is not reading the words in the same way that we read a book.
The light is reading the white and black areas on the paper. It is reading exactly where the black areas are and where the white areas are on the paper. The copier then transfers the information it reads directly to another piece of paper.
It is very difficult to explain how this is done, but to put it simply, a black powder, like charcoal powder, is applied to a blank sheet of paper to create a copy that is identical to the one that was read. A photocopier is a machine packed with the necessary equipment for this purpose.
A photocopier is a machine that first reads what it sees by light, then applies black powder to the white paper, and produces an identical image to the one it reads.
