Quadruple "quadruple-tone technique" tone technology is "quadruple-tone technique," who first used the first use of Canon Inc., which is controlled by the concentration of four ink droplets (blue and red of the concentration of products are diluted by two-thirds Black diluted by half, yellow no dilution) change, and control the number of times the print head at some point inkjet (divided 0-3 times, that does not spray, spray once, twice spray, spray three times) universal printer manufacturers, thus producing a change in the concentration of four ways to show any kind of subtle shades of color change, so that any color may exhibit subtle changes between scratch gradual, to achieve the "Photo" class effect. This technological breakthrough in the past with the resolution of the printer simply means to improve print quality limitations. This is another typical application of resolution enhancement techniques in color inkjet printer. We know that the fine image needs to be changed to reflect the color density, and the traditional way of sucked the standard cyan, magenta, yellow and black ink 100% sprayed onto the paper, not well reflect the changes in the concentration of . Common printer toner cartridges for laser printers Detailed rental market in accordance with the printer toner imaging modalities can be divided into four categories: negative electromagnetic toner, negatively charged non-magnetic toner, toner and positive positive electromagnetic non-magnetic toner.

This printer is not alarmist, do not believe you put the HP 1000, 5800 powder was added to the test on Samsung under this cartridge can not be used on machines equipped with positive flour Brother, Lenovo 2312, etc. Changping printer rental negatively charged non-magnetic toner free soft material, the friction newcomer negative. Only be used in Samsung, Lexmark, Epson and other non-magnetic roller, equipped with the negatively charged powder machine.
