Copier
A photocopier has become a standard piece of office equipment. While Xerox is the most famous company for making a copier, there are several other brands out there that make other kinds of office machines that make copiers as well. These devices are used to make copies of paper documents, as the name implies, by using light induced conductivity of a drum and toner inside the machine. Of course, the process is a little more complicated than that.
Before the Start button is pressed, the drum of the copier is already primed with positively charged ions.
Hitting Start has a strong light passing along the paper, and the drum rotates, gathering what light the paper reflects.
With a reaction, the particles on the drum only remain where the light didn't hit it.
Toner is dispensed and electrified along with a sheet of paper against the drum, causing the toner to stick to the paper in the shape of pictures and text that have been copied in the positively charged particles.
The fuser binds the toner to the paper and it comes out of the copier as a duplicate of the original piece of paper.
Copier are invaluable in today's businesses and offices because several things can require being copied. Usually it is important documents that require an office to use a copier, but other things such as reports, memos, and general informative papers are also a use for a copier. Copiers also run on toner, which is cheaper than printer ink, thus saving more money rather than printing out several copies on an ink jet printer.
