How does a copier work?
Question answers (1)
A copier, or photocopier, works by using a combination of light, static electricity, and toner to create a duplicate of a printed document. Here are the basic steps involved:
-
The original document is placed on the glass surface of the copier.
-
A bright light shines onto the document, which reflects the light onto a photoconductive drum inside the copier.
-
The light causes the photoconductive drum to become charged with static electricity.
-
The charged areas of the drum then attract toner particles from a rotating drum inside the copier.
-
The toner particles are transferred from the rotating drum to the paper, which is fed through the copier.
-
The toner is then fused onto the paper with heat, creating a permanent image that is an exact copy of the original document.
-
The finished copy is ejected into a tray, where it can be collected by the user.
This process happens very quickly and can produce multiple copies of a document in a short amount of time. More advanced copiers may also include features like automatic document feeders and collating, which can make copying large documents or multi-page presentations much easier.
