How to choose the right toner for printer Brother MFC-L3770CDW
When selecting toner for Brother MFC-L3770CDW, we recommend focusing on three things: the series (TN-243 vs TN-247), the color you need, and whether you want OEM or compatible. TN-243 is a popular standard-yield option for everyday use, while TN-247 is often chosen for higher yield and fewer replacements—especially useful in an office setting.
If you print mostly text: choose a strong black option (TN-247BK or TN-243BK), and consider a twin pack for continuity.
If you print color regularly: CMYK multipacks help keep colors consistent and reduce “one color ran out” surprises.
If print quality suddenly drops: it may be time for the DR-243CL drum unit rather than another toner.
If the printer stops with a maintenance alert: check whether the WT-223CL waste toner tank needs replacing.
Common Brother MFC-L3770CDW printing issues—and what usually fixes them
This model is very dependable, but like any laser device, it can display typical consumable-related symptoms. Here’s what customers most often encounter and how the right products from this category help:
Faded prints or uneven color – often resolved by replacing the specific color toner, or by checking the transfer unit BU-223CL if the issue persists.
Background haze / repetitive marks – frequently indicates a worn drum unit DR-243CL.
“Replace Waste Toner Box” message – time for the WT-223CL waste toner tank.
One color runs out quickly – multipacks (TN243CMYK or TN247CMYK) help maintain balance and keep your workflow smooth.
