You'll want to have one of these on hand when that toner light starts flashing: just snap this black toner cartridge into place and you'll be up and running again. Compatible with Brother laser printer models HL-2140 and HL-2170w, the TN360 has an expected lifetime yield of 2,600 pages (based on 5% coverage). Designed for optimal use with Brother name-brand consumables, its fine particles help produce the rich blacks and subtle shades of gray that help your pages look clear, legible, and cleanly professional-looking.
