Using genuine Xerox supplies lowers your maintenance costs and helps reduce service calls. Genuine Xerox cartridges generate optimum print quality and give you maximum uptime and productivity.This cartridge uses InkLogic, the Intelligent Color System from Xerox. Inklogic puts you in control with intelligent ink level sensors and the ability to replace one color at a time. The printer looks ahead at your print job and notifies you when a color is low so you don't waste ink, time or paper by printing a job with a color missing. When ink runs out, you replace only the color you need, no pages to reprint, no need to discard partially full ink cartridges.
