In a photocopier, the black powder, or toner, only sticks to certain areas of the paper due to the electrostatic process involved in the copying. The photoconductive drum inside the copier is charged and then exposed to light, which creates a latent image of the document. The toner, which is also charged, is attracted to the areas of the drum that have been exposed to light (representing the image), while repelled by the areas that remain charged. When the paper passes through, the toner adheres only to the specific areas that correspond to the image, resulting in the final printed output.

What is the working principal of the xerographic photocopier?
The dry paper copier, or photocopier, uses the photoelectric effect as its basic working principle. The process is to spray electric charge upon the smooth surface of a semiconductor and then flash an image to be copied onto this surface. The light causes the plate to discharge in that local area. When pigment powder is sprinkled over the plate it sticks to the charged spots and falls off the discharged spots. The plate is then placed in contact with a blank sheet of paper to which the powder is transferred. Then the paper is heated under pressure to stick the permanently pigment to the paper.
How does a photocopier use static energy?
A photocopier uses static electricity to transfer toner particles onto paper. The toner particles are given an electrical charge that is opposite to the charge on the photoreceptor drum. This causes the toner particles to be attracted to the charged areas of the drum and subsequently transferred onto the paper.
How can you get a jammed paper out of a photocopier?
To remove a jammed paper from a photocopier, follow these steps: Turn off the photocopier to prevent further damage. Open the machine's panels and look for the jammed paper. Gently pull out the paper in the direction it would normally travel. Close the panels and turn on the photocopier to resume normal operation.
What are the photocopier consumables?
Anything that has to be replaced regularly. For a photocopier the ink toners, paper and thermal film are some examples.
How are microprocessors used in photocopier?
The role of a microprocessor in a photocopier controls the display on the front of the machine. Also the microprocessor sends signal to the motor to move parts of the photocopier, so that the paper can come out.
How does a photocopier use static electricity?
A photocopier uses static electricity to attract toner particles onto the paper. The drum in the photocopier is charged with static electricity, which attracts the toner particles. When the toner particles are transferred onto the paper, the static charge helps to keep them in place until they are heat-fused onto the paper.
What does the duplex function on a photocopier allow you to do?
Copy to both sides of the paper
What is aphotocopier used for?
To make more of something on paper using only, paper, the original and of course, the photocopier.
What is the best kind of paper to buy for a photocopier?
There are different types of paper that can be put into a photocopier. The best kind are reams of paper that have been specifically designed for photocopies. Multi-purpose copier paper is an excellent choice. The weight should be 20 pounds with at least a 96 brightness.
What did civil war infantry use to store black powder?
Barrels and paper tubes.
What sticks to paper or black boards?
Many things stick to each of these things. That includes glue and tape.
How does one fix a paper jam in a photocopier machine?
One can fix a paper jam on a photocopier machine by: assessing the situation, locating the problem area, pull the paper out through the paper path and clear all stuck paper from the machine carefully including small pieces, close the machine and run a test page.
