Setup, Compatibility & Care
To install, open the printer's front access panel and remove the existing drum/toner unit. Carefully release the old cartridge and insert the Q-Connect toner until it clicks into place. This cartridge is fully compatible with: Brother HL-L8230Cdw, HL-L8240Cdw, MFC-L3740CDW, MFC-L3760CDW, MFC-L8340CDW, and MFC-L8390CDW. To maintain print quality, store unused cartridges in a cool, dark environment in their original packaging to prevent toner clumping. Avoid touching the developer roller to ensure clear, streak-free prints.
