By combining these four colors of toner in varying proportions, you can generate the full spectrum of color. There are several different ways of doing this. Some models have four toner and developer units on a rotating wheel. The printer lays down the electrostatic image for one color, and puts that toner unit into position. It then applies this color to the paper and goes through the process again for the next color.
Some printers add all four colors to a plate before placing the image on paper.
The paper simply moves past the different drum heads, collecting all the colors in a sort of assembly line. Inc. All rights reserved. Simply register for a free Postbox in the country where your merchant is located.
