Is your Brother printer (like the B2236dw or MB2236adw series) giving you streaks or faded prints? It's probably time to replace the drum unit, not the toner. This is a high-yield replacement drum unit that's compatible with those models. It's rated for about 12,000 pages (at 5% coverage), which should last you a good long while. The installation is usually pretty straightforward – just open the front of your printer, take out the old drum, and slide this new one in. Remember, this is just the drum unit; toner cartridges are sold separately. A cost-effective way to keep your printer running like new.
