fénymásolók

Fénymásolók, often referred to as photocopiers, are electronic devices that make quick paper copies of documents and other visual images. The process is called xerography, from the Greek words xeros (dry) and graphein (to write). In its simplest form, a fénymásoló works by creating a latent image of the original document on a charged, light-sensitive drum. This image is then developed using toner, a powder that adheres to the charged areas. Finally, the toner image is transferred to a piece of paper, which is then heated to fuse the toner permanently.

Modern fénymásolók are highly sophisticated and often combine multiple functions. Many are digital, meaning they scan the original document and store it as a digital file before printing. This allows for features like enlargement, reduction, collation, and duplex (two-sided) copying. Multifunction printers (MFPs) integrate fénymásolók with printers, scanners, and fax machines into a single unit, making them a popular choice for offices and homes. The technology behind fénymásolók has evolved significantly, moving from bulky, analog machines to compact, high-speed digital devices that are integral to modern document management.
