Mechanism of Color Printing
In color printing, the shape and color of images are expressed in groups of minute
cyan, magenta, yellow, and black dots.
Therefore, image data input in the printer are dissolved into cyan, magenta, yellow,
and black.
The data is developed in each cartridge, and toner is transferred onto paper
repeatedly.
When data in all four colors is transferred onto paper, the paper goes through the
fuser unit and is output.
