Photocopying is a phenomenon which creates copies of paper documents or other graphic images in a very quick time and at a low cost. The first of its kind was introduced by Xerox in 1960s.
Let’s look at the working of a photocopier step by step:
1.First and foremost, the surface of a drum is supplied with an electro-static charge produced by a high-voltage wire called a corona wire. A semiconductor material named selenium or germanium is used to coat the drum.
2.Secondly, a light (thin strips format) is beamed onto the image, which is only reflected by the white areas of the paper. The light is then directed towards the drum, which is specially designed to make it photoconductive. This is done to neutralize the positive charges from the light.
3.As a result, the charges have become opposite i.e. the white areas of the picture have become neutral and the black areas have become positive.
4.The toner is negatively charged. Hence, when it is in contact with the drum, it gets attached with the areas that are positively charged, just like paper sticks to a charged balloon.
5.The toner is then attracted onto a positively charged piece of paper.
6.The toner is nothing but a dry ink substance. If paper came out of the photocopier covered in dry toner it would just brush off, so the toner is heated to make it melt and to bind it to the paper.
Copying Machine Supply – Is leasing the right option?
Copier industry generates about $24 billion by selling over 1.5 million new copiers annually. No doubt this huge market prompts manufacturers to constantly improve their products on quality and performance, resulting in stiff competition among copier vendors. An average mid-level business copier can cost anywhere from $5000 to $10000 and the price can hike up to $40000 for the best office models. It is because of this high cost and ever changing technology, copier leasing becomes a preferred option for many business organizations than purchasing a new copier.
Beware of “copying machine supply” frauds
A copying machine supply fraud begins with a solicited call to a company’s employee asking him to buy a discounted copying machine supplies. What they offer are sub-standard products at high price or may be higher than the bargained amount.
Copying Machine Supply – A brief history of XEROX
Xerox came into existence in the year 1906. During that time it was referred as “The Haloid Company” which was into manufacturing of photographic paper and related equipment. But it was in 1959 when the company became popular with the introduction of its first plain paper photocopier.
