(2) Basic Color Printing Process
1) The machine has a toner cartridge of each color yellow, magenta, cyan and black as
shown in Fig.3-4.
2) The toner image developed using the primary colors is transferred to the transfer
drum for the printed color combination as shown in Fig.3-5 (a).
3) The toner image formed on the transfer drum is transferred to the transported paper
as shown in Fig.3-5 (b).
4) The toner on the paper is fused by the thermal fusing unit to fix the toner image onto
the paper as shown in Fig.3-5 (c).
Summarizing the above processes, a toner color layer is formed on the transported
paper, and subsequently, the color image is made through the subtractive process.
