The fastest way to get an answer to this kind of question is to visit the site of your printer's manufacturer presumably Brother. Check the model number of your printer and then look up the appropriate cartridge or cartridges listed as replacement compatible. You need the TONER number to locate it on Best Buy's website. You will likely need customer service assistance as BB has for some reason removed all of the "look up" information which is why you need to go to Brother first. ABSOLUTELY to not take the word of a customer service agent that a "strange" cartridge "will work". They won't!! I was initially advised that an HP cartridge would fit into my Brother HL-2040 Laser Printer. It didn't. Wasted a fair amount of time until the store closest to me worked out the problem. When you KNOW what you need, you are in a far better position to get what you want from a customer service agent who most likely does NOT know every product in the Best Buy inventory!
