When you use this Genuine Fuji Xerox Cyan Toner Cartridge in your DocuPrint C1190 FS, you will be using Fuji Xerox proprietary advanced Emulsion Aggregation (EA) toner. Emulsion Aggregation (E.A.) is a new process of “growing” each toner particle, rather than grinding down larger chunks to the required size. This produces finer particles with uniform size and shape that result in superior print quality. It enables the toner to be transferred to the paper faster and produces a sharper image than conventional toners. Consequently, transfer is consistent, text is clearer, coverage is more even and image quality is higher. At the same time, the innovative toner cartridge design makes toner replacement a breeze. Only genuine Fuji Xerox consumables achieve broader resolution enhancement in your C1190FS when the highest print quality is needed. Fuji Xerox technology automatically gives you the best results for photos, graphics and text.
