Experts answer: in the basic structure, and has just introduced color Ji Da Ji Da identical black and white, print controller, printing engine and print concepts like language is the same. The realization of basic principle, the color black and white Ji Da Ji Da and also the same. Toner is adsorbed on the surface of photosensitive drum to form toner Image, the toner transferred to the print paper, post-fixed by heating. Through continuous process, complete print job. The difference is, color Jida order to obtain color image printing, you must use more sophisticated toner and image transfer steps, and these steps will inevitably result in color and black and white Ji Da Ji Da in Print speed Gap. Can only produce black and white Jida different draft gray black and white printing, reason is that it only uses black ink, toner distribution depend on the number of different gray-scale intensity of the decision to print. If you want to achieve color printing, you must use a variety of colors of ink, toner stack merge generated by the play of color India pixels. As with inkjet printers, color Jida use CMYK color system, the use of blue (Cyan), Magenta (Magenta), Yellow (Yellow), Black (blacK) four different colors of ink, and print through the same four loop transfer toner to print the paper . After re-heating, melting, combined with a permanent fixed toner on paper, so to achieve a variety of color printing. However, the various printer manufacturers to achieve four specific programs print cycle is different. Currently there are two most common techniques: one is black and white Jida side drum used in Type, the other is sensitive with a way. Photosensitive drum is rather simple, when dealing with a color, the toner is adsorbed on the surface of photosensitive drum fixed, then the second color toner and then directly added to the top, followed by a third, fourth, until CMYK four colors of toner are all attracted to the photosensitive drum table Face up. Then, all the toner is printed on paper with heat transfer to fixed. Contrast with the light-sensitive way, it drum next to the additional transfer a tape to deal with a color toner, the toner will start with drum frequency straw San Fat Man walk around to defend play slow toad H Xieyinmoulong Piqianchiou Pan cave shrimp Disorder which restored cup husband Jia humorous flag mattress Tsang frequency own order defend rare MYK after dealing with the four toner, then transferred from the transfer tape to the print paper uniform heating fixed. These two programs not only to achieve technically different, the composition of the corresponding structure of the printer is different, but in the end office Were consistent with management. Is a one-time transfer of toner to the print paper, were not transferred, after all, doing so would result in different colors can not mix full color printing ineffective. As the color Ji Da Ji Da is equivalent to repeated 4 times black and white printing process, which in theory is only black and white print speed of a quarter of Jida . Therefore, developing new technologies to improve the printing speed becomes the printer manufacturers and engine manufacturers focus. Early color Jida products to perform more poorly it uses lame halftoning, by visual deception to create "color printing" illusion. This technique can only control half-tone toner "There," "no", but can not control its concentration. Toner particles far smaller than the print due to pixel size, so a pixel must be many common composed of fine toner particles. Since the human eye can not distinguish between such small size, and "mistake" is the integrated form of the color toner, but this is actually An illusion. If we are thousands of times a print pixel magnification observation, will find that the proportion of pixels filled with different, different arrangement of blue, magenta, yellow and black toner of four colors, the toner and not really mix . This mechanism will inevitably lead to the early color Jida not print well Color fidelity, distinct, smooth transition of images, print quality average. Of course, this long history, today is quite different with the previous color Jida. It can not only control the graphite powder and without, and the specific number, but also to control the duration of laser irradiation to determine the concentration of a pixel Ratio (for each color in the allowed 256 concentration), while at the same location also allows stacking a number of different color toner. In the final stage, which will be heated toner melt together, forming a true color pixels. Reference: http: ** www.pcpop.com * doc * 0 * 111

- That printer, you first think of the three brands are:
- What is the amount of ink drums? Do not know ah! !
- EPSON7800 appear dark green longitudinal horizontal stripes print how to do?
- Local area network printing problems
- After refilling cartridges really easy to use?
- Printer can not print continuous
- EPSON7800 what color printing using the configuration file is better?
- quickimagenavigator
- Why does my computer screen is always such a prompt?
- EPSON7800 use paper which is better?
