This toner is advertised by Brother as an 8000 yield. MAYBE, if you are running single side prints of double spaced print on a contrast mode that is very light. True capacity is about 4800. I am currently producing a book that is 800 pages of double sided printing. One cartridge is producing about 6 books at normal contrast. It may be cheaper to print this on my laser printer! Until LD has a after market cartridge on this, it is a pricey amount for the yield.
