What Toner Does the Brother MFC-L3770CDW Use?
Nov 8th 2026
Quick answer: The Brother MFC-L3770CDW runs on TN223 standard-yield or TN227 high-yield toner — black, cyan, magenta and yellow, one cartridge each. Ratings: TN227BK black about 3,000 pages, TN227 colors about 2,300 pages apiece, TN223 black about 1,400 and TN223 colors about 1,300. The four cartridges sit in a DR223CL drum set with a life of roughly 18,000 pages.
The Flagship: Built Around the Document Feeder
Every family has a model where the options list runs out, and this is it. The MFC-L3770CDW prints, copies, scans and faxes at up to 25 pages per minute, and its signature talent sits in the feeder: a 50-sheet automatic document feeder that scans both sides of a page in a single pass, at duplex speeds up to 58 images per minute in black and 34 in color. Add NFC "touch to connect" printing and scanning, a 30-sheet multi-purpose tray for envelopes and letterhead alongside the 250-sheet main tray, a 3.7-inch color touchscreen, and Wi-Fi, Ethernet and USB connections, and you have the complete version of this design.
A machine bought to chew through two-sided paperwork drinks toner at the family's fastest rate. That is the context for everything below.
What Each Cartridge Delivers

| TN223BK | Black | ~1,400 | $25.26 | ~1.8¢ |

Yields are Brother's ISO/IEC 19798 ratings; prices were read from the main price element of our product pages on November 2, 2026. Duplex scanning has a toner consequence owners overlook: a two-sided original scanned and copied produces two printed sides, so a feeder full of contracts can spend a visible slice of a cartridge in one sitting. At the standard-yield rate of roughly 1.9 cents a color page, that habit costs nearly twice what it needs to — the high-yield shelf exists precisely for this machine's workload. The box starters, around 1,000 pages per color, are best treated as a first month, not a first year.

Set Versus Singles at Flagship Volumes
The compatible TN227 four-color set was $52.79 at the checked date, against $101.04 for four singles — a saving near $48 on every full cycle. High-volume machines cycle colors together, so the set aligns with how this printer actually empties: when one high-yield color is done, the others are typically within a few hundred pages. Singles retain one honest role — the emergency replacement. If yellow dies the morning of a deadline while the rest show a third remaining, a single TN227Y today beats a set bought early. Keep that pattern in mind and the two formats stop competing; they take turns.
Replacing a Cartridge
Leave the power on, open the front cover, and slide out the drum assembly of the exhausted color. Press the lock lever, lift the old cartridge away, rock the new one side to side several times, and strip off its protective cover. Press it into the drum until the lever re-engages, run the green corona tab across the drum and back to its home arrow, and return the assembly. Repeat as needed for any other color, then close the cover and let the machine re-read its counters before judging the first test page.
The Rest of the Consumable Map
Toner is the fast-moving layer. Under it, the DR223CL drum set — four drums — is rated around 18,000 pages; our store listing for the set showed an 18,500-page yield at $86.11 when checked. Duplex-heavy machines reach drum age sooner in calendar time, so repeating spots or a gray cast that follows one color should be read as a drum signal. The BU223CL belt unit and WT223CL waste toner box, each good for roughly 50,000 pages, are the deepest layer; at flagship pace they are genuine mid-life service items rather than trivia.
MFC-L3770CDW Questions
How fast is the two-sided scanning, really? Brother rates single-pass duplex scanning at up to 58 ipm in black and 34 ipm in color — both sides captured in one pass through the 50-sheet feeder, with no re-feeding.
What is the multi-purpose tray for? Up to 30 sheets of the awkward stuff — envelopes, letterhead, labels, card stock — fed straight without bending through the main tray's path. It is the difference between printing a mail merge of envelopes and dreading it.
Can I print by tapping my phone on the printer? Yes. NFC touch-to-connect pairs a compatible Android phone or tablet by contact, for printing and scanning, even without joining the office network first.
Does heavy duplex copying wear the drums faster? Drums are rated in pages, and a duplex page still counts once per side imaged. Two-sided workloads reach the DR223CL's roughly 18,000-page horizon sooner in calendar terms simply because more pages pass per day.
Is the TN227 the largest cartridge this printer accepts? Yes — TN227 is the high-yield ceiling for this family. There is no larger official size, which is another reason the four-color set's pricing matters at this model's volumes.
