Bests & Worsts Reviews from Amazon

. I get 800 to 1100 extra copies from each cartridge. After the "Toner Life End" message appears, it refuses to print even one more copy. Offensive...until you show it who's in charge. Remove the cartridge and find 2 clear plastic port holes, one on each side. The printer shines a light through these to decide when to shut you off. But it's too sudden and too early. Cover one or both windows with a small piece of masking tape. You can put the tape on the outer drum unit holes if you prefer. I get about 3400 copies per cartridge instead of 2400. I really like Brother printers now that I have taught them some manners. To save even more money try SOL Corp (Non-OEM) 2-Pack Toner REFILL KIT for Use in Brother Tn-350 Toner Cartridge. ~~~ Comments & questions welcome ~~~
