The Brother TN227C High Yield Toner Cartridge is expensive but it is indeed “high yield”. The cartridges last roughly 18 months in my home laser printer with which I average about 4-5 color printed pages per day. With three color and one black toner cartridges in the printer, ~$250.00 worth of OEM toner seems like a lot to pay for 18 months of printouts, but unlike all of the inkjet printers I have owned, my Brother laser printer has worked continuously for five years completely trouble-free, and to me, that alone makes the cost of the toner a worthwhile investment.
