What you want is for the white areas of the original sheet of paper to NOT bring in toner. In some way the toner has to get onto the drum and after that onto a sheet of paper.


The sheet of paper gets charged with fixed power, and it draws the toner off the drum.

The pigmented powder made use of to create the image is called toner. Toner particles made of colourant and plastic resin have actually precisely managed electrostatic properties as well as variety from regarding five to 10 micrometres in diameter.

The light bounces off the white parts of the initial record, as well as via mirrors, it is shown onto the drum, which has actually been provided a positive electrical fee.


Where the light drops (the white parts of the original document), the drum performs, and the electrostatic cost is shed. Where there is no light (the black parts of the file), the drum does not perform as well as maintains its positive cost.

In the fusing procedure, the toner making up the photo is thawed and adhered to the paper. This is completed by passing the paper through a pair of rollers. A warmed roll melts the printer toner, which is fused to the paper with the aid of pressure from the 2nd roll. Clean.


The final process entails warm to take care of the toner to a sheet of paper. The copier checks the surface area of the glass (the bright light).


Where the light drops (the white parts of the initial record), the drum conducts, and the electrostatic cost is lost. Where there is no light (the black parts of the paper), the drum does not carry out and maintains its favorable cost. An image is generated onto the surface of the drum, but the image is composed of favorably billed static electrical power.
