Question

Which lens is used in the photocopier?

Answer 1

Hint: To make copies of images and documents we use an electronic machine known as a photocopier. The photocopier is an older term which is used for today’s multifunction printers and copiers. Photocopiers use imaging technology also known as xerography. This is used to duplicate an image that is placed on the scanning glass of the machine.

Complete answer:
The photocopier works on two fundamental principles. One of which is the fact that the opposite charges attract and the second is the tendency of certain materials to become more electrically conductive after absorbing electromagnetic radiation or visible light.
Now the answer to the above-mentioned question is that the lens that is used in the photocopier is convex. The lens works like the usual lens that is in our phone. This lens allows us to focus the copy of the image on a specific plate.

Therefore the lens used in the photocopier is convex.

Additional Information:
Photocopiers work on the principles of electricity and photoconductivity in order to work. A light-sensitive photoreceptor will be placed inside the machine. This machine will attract first and then transfer toner particles onto plain paper to form a copy of a document. This is a short version of photocopiers works.

Note: A photocopier has five parts. They are a photoreceptor drum, a toner, corona wires, a light source, and a fuser. Xerography was developed in the late Ninety forty’s and because of this imaging technology photocopiers are called the Xerox machine. Today’s photocopiers do not just make copies it does many other functions other than making copies.
