All manufacturers rate their print cartridges at 5% yield.   At 5% yield and purchasing cartridges separately, the average non-Xerox black & white cost per page is 3-5 cents.   At 20% coverage, that costs would be 12-20 cents per page.  For color, the average non-Xerox cost per page at 5% yield is 14-17 cents.   At 20% coverage, that costs would be 56-68 cents per page.
Our Print Management Solution provides cost control with a fixed cost per pages regardless of coverage or toner/ink used.  For more information on our Print Management Solution, click here.
