What is the difference between color laser printer and black-white laser printer?

The biggest difference between color laser printer and black-white laser printer is the engine structure, color laser printer using C (Cyan, blue) M (Magenta, magenta) Y (Yellow, yellow) K (Black, black) 4 color carbon Powder to achieve full-color printing, so for a page of color content to go through CMYK reconciliation to achieve a page of content to print through CMYK 4-color toner 1 printing process.

In theory, the color laser printer have four sets of black and white laser printer exactly the same institutions to achieve color printing process. In order to streamline the organization and save costs, the current color laser printer in the structure of the use of a large number of 4-color separation, the other, such as paper feeding mechanism, photosensitive drum, fixing unit 4 color sharing a set of systems. So in the printing process, the paper to go in the engine to go through four identical processes, but in the four processes were to achieve a color transfer, which is currently the majority of color laser printer color printing speed in general Is an important reason for a quarter of the black and white print speed.

Color laser printer used in two forms of photosensitive units, one is used in black and white laser printer drum way, the other is the photosensitive belt way. In addition to the four basic colors of CMYK, all other colors are generated by the harmony of these four colors of toner, so the color laser printer work flow, before the fixation to have a 4-tone process. In order to better achieve the color harmony, color laser printer used in the reconcile oil (also known as fixing oil, the general use of silicone oil), in the use of blending oil, different manufacturers of products are different, most color laser printer There is a separate blending oil box, in the fixing at the same time to the media to add blending oil, which is most of the color laser printer print out the contents of an important reason for oil. Some of the color laser printer products, represented by HP's
Color LaserJet Pro M452dn and Color LaserJet Pro M452nw, use another reconciliation technology to remove a separate blending tank in the machine, but to combine the blending oil with the toner cartridge Together, in each of the small toner particles are wrapped in a middle of a blend of oil particles, not only simplifies the internal structure of the machine, but also to print out the contents of the oil greatly reduced.
