Black and White Copier Is the Workhorse

A black and white copier has been the fundamental support for workgroups since the first plain paper copier was announced in 1959 by what would become the Xerox Company. In a process invented by a physicist named Chester Carlson, xerography suddenly enabled widespread transmission of a piece of information to hundreds of people. Like most inventions, xerography took years and years of thought and planning by Carlson and others until it was perfected for commercial use.

Why a physicist? It makes perfect sense when you realize that the principles underlying xerography revolve around electrical charges. Simply put, positive charges are infused in paper which then attracts the toner, which is then fused by heat to the paper. When summarized, this sounds obvious, but it took years of experiments to finally create a clear, permanent image.

Modern Copy Machines

Once the process was realized, a business copier soon became a must-have machine. Gone were messy carbon copies and wasted time making corrections! Gone were dittos that were a staple of classroom instruction! The use of copiers spread rapidly because they were an astronomical advance in communications.

Today, there is such a variety of machines it is sometimes difficult to choose between this black and white copier and that black and white copier. Major electronics and imaging companies manufacture copiers that not only turn out sharp black and white images, but true-color images as well. Color copiers are now so technically advanced that professionals can use them for graphics.
