What Is Photocopier?
A Photocopier (also called copier or copy machine, and formerly Xerox machine, the generic trademark) is a machine that makes copies of documents and other visual images onto paper or plastic film quickly and cheaply. Most modern photocopiers use a technology called xerography, a dry process that uses electrostatic charges on a light-sensitive photoreceptor to first attract and then transfer toner particles (a powder) onto paper in the form of an image. The toner is then fused onto the paper using heat, pressure, or a combination of both. Copiers can also use other technologies, such as inkjet, but xerography is standard for office copying.
Photocopying is widely used in the business, education, and government sectors. While there have been predictions that photocopiers will eventually become obsolete as information workers increase their use of digital document creation, storage, and distribution and rely less on distributing actual pieces of paper, as of 2015, photocopiers continue to be widely used. During the 1980s, a convergence began in some high-end machines towards what came to be called a multi-function printer: a device that combined the roles of a photocopier, a fax machine, a scanner, and a computer network-connected printer. Low-end machines that can copy and print in color have increasingly dominated the home-office market as their prices fell steadily during the 1990s. High-end color photocopiers capable of heavy-duty handling cycles and large-format printing remain a costly option found primarily in print and design shops.
What Are The Types Of Photocopying?
- Black and white (mono) copiers.
- Colour copiers.
- Network copiers.
- Multifunctional copiers.
- Desktop copiers.
- Wide-format copy machines.
What Is Photocopier Used For?
copier, also called photocopier, copy machine, photocopy machine, copier machine, or photocopying machine, a device for producing copies of text or graphic material by the use of light, heat, chemicals, or electrostatic charges.
How Does Photocopier Works?
- Charging: cylindrical drum is electrostatically charged by a high voltage wire called a corona wire or a charge roller. The drum has a coating of a photoconductive material. A photoconductor is a semiconductor that becomes conductive when exposed to light.
- Exposure: A bright lamp illuminates the original document, and the white areas of the original document reflect the light onto the surface of the photoconductive drum. The drum areas that are exposed to light become conductive and therefore discharge to the ground. The drum area not exposed to light (those areas that correspond to black portions of the original document) remains negatively charged.
- Developing: The toner is positively charged. When it is applied to the drum to develop the image, it is attracted and sticks to the negatively charged areas (black areas), just as paper sticks to a balloon with a static charge.
- Transfer: The resulting toner image on the surface of the drum is transferred from the drum onto a piece of paper that has an even greater negative charge than the drum has.
- Fusing: The toner is melted and bonded to the paper by heat and pressure rollers.
A negative photocopy inverts the document’s colors when creating a photocopy, resulting in letters that appear white on a black background instead of black on a white background. Negative photocopies of old or faded documents sometimes produce documents that have better focus and are easier to read and study.
What Is The Maintenance Of Photocopier?
This simple task can significantly extend the life of your machine. Daily care and maintenance tasks include removing paper drawers, checking for stuck paper, clearing paper jams, checking toner levels and cleaning rollers and glass.
Useful Life Of Photocopier?
Depending on the model, a typical life span on an office copier can range from three to five years. The life span of your copier largely depends on the copy volume and maintenance. Most copier models are designed to produce 1,000 copies per month at the low end, with higher-end copiers producing upwards of 50,000.
