Introduction: Social media platforms have developed at rocket’s speed and have generated a users’ engagement regardless their age, education background, profession, location, and others. For instance, Face book, Twitter, Pinterest, blog and the website bring to them the convenient and fast communication to convey messages associated with imagery, video, and audio. They email, converse, chat, post anywhere and anytime they want to share their experiences immediately. It is a sort of communication among friends and family members different from working style in an office that need the formality. In other words, it is a kind of informal exchange of information and news. This explains why the presence of a photocopier is still meaningful in a workplace. Conventional hard-copy letters are widely used in the process of transaction in governmental offices and companies on daily basis. The overwhelming advantages of social media tools can not lessen the importance of a photocopier in the office in the digital world. In the office work, it requires the etiquette of formality, for instance, a business letter between two firms needs written signatures of CEO’s or a contract of an upcoming project should be printed in a hard copy that demands a co-sign of bilateral partners. The advantage of a soft copy is to be easily, conveniently recorded and retained for a long time while a hard copy is needed as it holds a legal value. The photocopier is an office tool mainly to serve in business, education, and government sectors. A photocopier is named as a copy machine that makes copies of paper documents and images cheaply and quickly. Today office workers mostly use photocopiers in workplaces under the technology named xerography. Chester Carlson (1) invented this copying machine in 1938 and it took a decade before his intellectual property was recognized. Its name gradually changed to the memorable name “xerography”. The Xerox Corporation, a photocopier giant, was born in 1949 and developed and commercialized it. A photocopier is used commonly because it creates high-quality text and graphic images on a piece of paper. Xerox is the first photocopier firm in the printing market, thus, office workers who don’t realize the company trademark and the copier machine call it as xeros machine. The process is primarily named as electrophotography that includes two parts: the attraction of materials of opposite electrical charges and the formation of some conductors of electricity when materials are exposed to light. There are six steps that moves an image from one surface to another applying these parts. When the photo of a document exposes to a photoconductive surface because the illuminated sections (the non-image areas) become more conductive, the charges disappear in the exposed areas. Negatively charged powder sticks to the positively charged image areas. The negatively charged stuff is drawn to the surface of paper when it leaves the photoconductor. Then, the powder image is created through the process of heating and a photocopier produces a perfect copy of the original image. Body: To start a photocopier, a user realizes four simple, basic steps that are normally instructed on the lid of a photocopier for a user’s reference as follows (2):
Below describes the operation of today’s photocopier:
Conclusion: The manual operation of a photocopier is easy and simply but Xerography is a complicated process in which chemical, electrical, mechanical and software know-how play a key role. The six-step circle of a photocopier describes functions and operation of parts of a photocopier. A photocopier provides on-demand printing of complete documents such as leaflets and books that are widely used in business and education. Recommendation

Later, his nephew sold them at price of 1.2 million dollars. Multi-millionaire Mo Gawdat came to a similar conclusion as Albert Einstein. He was a Google executive. His life ticked every box. When he wanted a car, he purchased a vintage Rolls-Royce at the drop of a hat. Many thought his life was perfect. He got married with a university sweetheart and fathered two beautiful children. Indeed, his life was as miserable as sin. Vietnamese farmer Ngoc Thai got a fever and has not slept since then. His story has not been studied by scientists.

There is a connection between sleep and cancer, obesity, diabetes and poor mental problems. Less 6-hour sleep per day causes cancer-fighting cells to drop 70%. In 1942, 92% people slept more than 6 hours but nowadays 50% of them have less 6 hours of shut eye. People who have sleep loss are 200% more likely to live a short life that normal people. |
