We are sorry to hear that you are having issues with the toner yield. Stated page yields for genuine Brother cartridges are based on the ISO testing standards. Third-party cartridges sold as “compatible” for Brother printers may not strictly adhere to the ISO Standard to determine their advertised page yields, therefore they may not be comparable to Brother Genuine cartridges. The number of pages that can be printed with a cartridge is affected by several factors, including paper size, number of pages per print job, amount of print on each page, font size, and print content (graphics, charts, etc.). Print jobs with large text fonts, graphics, charts, and/or large amount of solid coverage (black or any given color) will use much more toner and will shorten the life of the toner cartridge. Please verify you have purchased a new Brother Genuine cartridge by following the steps on this website: https://www.brother-usa.com/supplies/ink-and-toner/security If you have any questions about your Genuine cartridge, please contact Brother customer service at www.brother-usa.com/support.
