Brother MFC-L3770CDW Toner Cartridges FAQs

What toner does the Brother MFC-L3770CDW use?

Brother printer MFC-L2740DW uses the standard yield TN-223 black, cyan, magenta, and yellow toner cartridges. It is also compatible with the high yield TN-227, which comes in the same color variation. These toner cartridges will work as a replacement for the original counterpart at a very affordable price!

Why are toner cartridges so expensive?

OEM ink and toner manufacturers claim that the high cost of these cartridges is due to the research and development of technologies to deliver high-quality ink and toners. However, it is worth noting that there are generic cartridges that exceed OEM requirements while being less expensive than their counterparts. CompAndSave's compatible and replacement ink and toner cartridges are engineered to meet or exceed OEM standards. That means to say, you can have the same print quality and page output without spending a fortune. Please keep in mind that using generic, remanufactured, or replacement cartridges will never void the warranty on your printer. For additional information, please visit our Ink Knowledge Base.

Why won't my Brother printer recognize the toner cartridge?

Most probable reason is the toner cartridge and drum unit was not properly installed inside the printer. To resolve this, remove and reinstall the toner cartridges by following the replacement instruction above. If you still see this error after reinstalling, the next step would be to reset the printer by pressing the power button about seven times.

    Review for Compatible Brother DR223CL Drum Unit - DR223BK- Black
    Jul 17, 2021
    By: Verified Buyer
    Works well after you get the Brother toner cartridge seated. There is difficulty and why 4 stars, not 5. Difficult to get the cartridge to seat properly and stay clicked in place in the drum unit. This needs some work on CompandSave's end.
