fénymásoló

A fénymásoló, commonly known as a photocopier or xerographic copier, is an electronic device that makes paper copies of documents and other visual images quickly and cheaply. The process works by creating an electrostatic charge on a light-sensitive drum. When light reflects off the original document, the charged areas on the drum attract toner particles, forming an image. This toner is then transferred to a piece of paper and fused by heat, creating a permanent copy.

The term "fénymásoló" is the Hungarian word for this device. The technology was pioneered by Chester Carlson, who patented the process of electrophotography in 1938. The first commercial photocopier was developed by the Haloid Company (later Xerox) in the 1950s. Early machines were large and complex, but over time, photocopiers became smaller, faster, and more sophisticated, incorporating features like color copying, collating, and duplexing (copying on both sides of the paper).

Modern fénymásolók are often multifunctional devices, combining copying, scanning, printing, and faxing capabilities into a single unit. They are indispensable tools in offices, schools, libraries, and homes, facilitating the efficient reproduction of information and documents. The underlying xerographic principle remains the core of most photocopier technology, though advancements have continuously improved speed, quality, and efficiency.
