What are the 5 steps of photocopying?

In addition, the xerographic process is actually used to make both copies and prints….Heres how the process works today:

• Charge. Inside every copier and laser printer is a light-sensitive surface called a photoreceptor.
• Expose.
• Develop.
• Transfer.
• Fuse.
• Clean.

What is the process of photocopying?

Most modern photocopiers use a technology called xerography, a dry process that uses electrostatic charges on a light-sensitive photoreceptor to first attract and then transfer toner particles (a powder) onto paper in the form of an image.

Which photocopying method is still in use today?

electrostatic photocopying method
Today. Of the methods discussed in this lesson, only the electrostatic photocopying method is still in use today. Other methods in common use today in addition to the laser printer are: The inkjet printer that uses ink heads controlled by a computer to print text and images.

What elements are used in photocopiers?

The process of photocopying For example, when light is absorbed by some of the electrons (particles that have a negative charge) that make up selenium (a nonmetallic chemical element that is used in the photocopying process), the electrons are able to pass from one atom to another when voltage is applied.

Which metal is used for xerography?

In most printing applications the photoconductor is a metal drum that is coated with amorphous selenium and mounted to rotate around its axis. Selenium is used because it is able to hold and conduct charges in the absence and presence of light.

Which lens is used in photocopier?

convex lens
The photocopier uses a convex lens.

What is textile wet processing?

Textile wet processing is the process that use in any finishing treatment. Where, this process is applied on textile in form of liquid with involves some for chemical action on the textile. Examples: bleaching, printing, dyeing and printing. Figure 1 : Textile wet processing flowchart

What are the methods of wet processing?

During this process, the fabrics is wet out in water and allowed to lie damp for several hour. Other than that, the method is most popular that has been used in this wet processing is by using enzyme. This enzyme are named after the compound break down. Beside that, the other method is acid hydrolysis.
