Brother TN-660 Original Toner Cartridge - Twin-pack - Black Laser - High Yield - 2600 Pages Black (Per Cartridge) - 2 / Box

The most important words in replacement cartridges. Original Equipment Manufacturer. I worked 17+ years in IT and saw many replacement toner cartridges and saw the problems with 3rd party and "bulk refill" cartridges. The allure is absolutely understandable because of the insane prices of most refills; but what good is saving money on a refill if it tracks toner on every page until you replace it two or three times or once with an OEM? My employer had a contract with a company that supplied REFILLED cartridges and at least half the time they tracked toner on the prints. This meant cleaning the fuser and the paper path and round and round until the inevitable toner re- replacement. Replacing a new used cartridge with a new OEM cartridge always got rid of the tracking unless the used replacement got the fuser too dirty. What a pain. I had the same results after getting a Brother B/W laser at home. I highly recommend this OEM replacement especially since it is a high yield replacement. And it is pricy, but not ungodly expensive.

I bought an after-market toner that just did not work and I had toner everywhere! So I bought this one at Sam's and it works great! My last one lasted me 2.5 yrs and I do a lot of printing. Sam's had the best price and could get it to me the fastest. Very pleased.
