XEROGRAPHIC Meaning and
Definition
-
Xerographic refers to a process of copying or printing documents using electrostatic principles. The term originated from the Greek words "xeros," meaning dry, and "graphos," meaning writing. This technology uses a photographic technique without the use of liquid chemicals, instead relying on dry surfaces and electric charges.
In the xerographic process, an image is created by placing an original document on a glass plate of a copying machine, which is then illuminated by a light source. The illuminated document reflects light onto a charged drum, typically made of a photoconductive material. The areas exposed to light lose their charge, while the unexposed areas retain their charge.
Next, the drum is coated with a fine, positively charged electrostatic powder known as toner. The toner particles are attracted to the negatively charged areas remaining on the drum, creating a visible image. This image is then transferred onto a piece of paper or other printable material. Finally, the toner particles are fused onto the paper using heat or pressure, resulting in a permanent reproduction of the original document.
Xerographic technology revolutionized the field of copying and printing, offering a faster and more efficient alternative to traditional methods. It became widely popular in office environments due to its ability to produce high-quality copies without the need for hazardous wet chemicals. Xerographic devices, commonly known as photocopiers or laser printers, are still extensively used today for various document reproduction needs.
Common Misspellings for XEROGRAPHIC
Etymology of XEROGRAPHIC
The word "xerographic" is derived from the combination of two Greek roots: "xeros" meaning "dry" and "graph" meaning "to write" or "to draw". The term was coined by American physicist and patent attorney Chester Carlson in the 1930s when he was developing a method of dry copying called "xerography". The prefix "xero-" refers to the dry nature of the process, distinguishing it from wet or liquid-based copying methods that were prevalent at the time. Hence, "xerographic" describes anything related to the dry copying process of xerography.
