Review on 🖨️ V4INK Compatible Toner Cartridge Replacement for Brother TN360 TN330 - 4 Pack Black Toner for Brother DCP-7040 DCP-7030 MFC-7840W HL-2140 MFC-7340 Brother MFC-7440N HL-2170W HL-2150N Printer by Brian Trujillo

If you have a laser printer that uses a toner cartridge and you can use this as a replacement, no problem. I have found that this cartridge fits my Brother MFC-7840W just as well as it does my Brother toner cartridge. I've tried other so-called "replacement" toner cartridges that used to be cheaper, but they didn't fit in the printer and after a while they started streaking my printouts. I saw this toner cartridge at Costco and thought it might be worth a try as I have found that Costco offers quality products but I didn't want to buy a pack of 3 cartridges so I ordered one from Revain. This Innovera brand cartridge does a great job with my prints and I would definitely choose it again over any other 'replacement' cartridge.
