Frequently asked questions

What toner does the Brother MFC-L3770CDW use?

The Brother MFC-L3770CDW uses TN223 standard-yield (approx. 1,400 pages black / 1,300 pages color) and TN227 high-yield (approx. 3,000 pages black / 2,300 pages color) toner cartridges, plus the DR223CL drum unit (approx. 18,000 pages).

What is the difference between the TN223 and TN227?

Both fit the MFC-L3770CDW. The TN227 (also written TN-227) is the high-yield version — about 3,000 pages black and 2,300 pages color, roughly twice the pages of the standard TN223 — so it lowers your cost per page. If you print regularly, step up to the TN227 high-yield toner cartridges.

Does the Brother MFC-L3770CDW need a drum unit?

Yes. The MFC-L3770CDW uses the Brother DR223CL drum unit (also listed as DR-223CL), rated for about 18,000 pages. Replace it when print quality degrades — streaks, spots or faded prints — even if toner remains.

Are compatible TN227 toner cartridges safe for my Brother MFC-L3770CDW?

Yes. Our compatible cartridges are engineered to meet or exceed Brother's specifications and are backed by a lifetime warranty. Using compatible cartridges does not void your printer's warranty.

Which cartridge is the best value for heavy printing?

For the heaviest printing, the TN227 high-yield cartridge (about 3,000 pages black / 2,300 pages color) gives the MFC-L3770CDW its lowest cost per page. For occasional printing, the standard TN223 is the most economical upfront.
