It&rsquo;s just a matter of pressing a button of the xerox machine and hey Presto! a piece of paper comes out at one end, an exact duplicate of the document we needed copied!</p> <p>However, when the invention was first patented, nobody wanted anything to do with it. Major corporations like IBM, Kodak and General Electric rejected the offer to develop it, perhaps regretting the decision to this day! However, the blood, sweat, and tears of its inventor, Chester F. Carlson did not go wasted, as the success of the machine proves today!</p>
