What is the photocopying process?

Photocopying is the process of photographically reproducing a document of text, illustrations, or other graphic matter. The most common photocopying method used today is called xerography (from the Greek words for “dry” and “writing”).

What are the three parts of photocopier?

Inside a Photocopier Photoreceptor drum (or belt) Corona wires.

How does a photocopier or scanner work?

If the machine is a photocopier, it simply prints the digital image onto one or more blank sheets of paper. If the machine is a scanner, it stores a digital copy of the image and transmits it to a computer (via email or network), or stores it on a USB or memory card.

How a photocopier uses static electricity?

How does a photocopier use static electricity? To make a new copy, the paper that you are copying is placed downwards onto a sheet of glass. Using static electricity, an image of this paper is projected onto a positively charged drum. The coating on the drum can conduct electricity when light hits it.

What is the corona wire?

A charged wire in a laser printer that draws the toner off the drum onto the paper. It must be cleaned when the toner cartridge is replaced.

How does a photocopier work using static electricity?

The drum selectively attracts toner. Then the sheet of paper gets charged with static electricity and it pulls the toner off the drum. The toner is heat sensitive, so the loose toner particles are attached (fused) to the paper with heat as soon as they come off the drum.

What is difference between copy and scan?

While scanners and copiers operate in much the same manner, their output is different. A copier transfers documents directly onto the paper. It can copy large volumes at once without having to go through a computer, whereas a scanner creates digital versions of the documents that live on your computer.

Do photocopiers use ink?

Photocopiers don’t use liquid ink, they use what’s called toner, which is a dry powder contained in a cartridge. While the process is pretty complex, it’s basically a combination of light, heat and static electricity.

What is a printer Corona?

Corona treaters are integrated in-line on printing presses and digital printers to remove contamination, increase surface energy and provide a surface suitable for printing. Printers using water based, solvent based and UV inks benefit from adding in-line bump treatment to their lines.

Which rays are used in photocopy machine?

As glass transmits ultraviolet rays between 325 and 400 nanometers, copiers with ultraviolet-producing lights such as fluorescent, tungsten halogen, or xenon flash, expose documents to some ultraviolet.
