What Does MFC-L2740DW Toner Cost per Page?
On November 2, 2026, Staples listed Brother's TN660 at $71.49 and the TN630 at $48.79, and Quill also listed the TN660 at $71.49: about 2.7¢ and 4.1¢ a page. Our compatible TN660 is $24.95, about 1¢ a page. The drum adds a little: Staples' DR630 is $112.79 (about 0.9¢ a page over 12,000 pages), and our DR630 is $34.95 (about 0.3¢).
Will Compatible Toner Work?
Yes. The TN630 and TN660 have no chip; the printer recognizes a fresh cartridge through a small reset gear on the side of the cartridge, and compatible cartridges carry the same gear. Brother says it does not recommend non-Brother supplies and that its warranty does not cover damage they cause, but compatible TN660 cartridges are a common way to run this printer. If a "Replace Toner" message stays on after a swap, take the toner out of the drum, reseat it until the green lever lifts, and close the front cover firmly.
How Do I Replace the Toner in the MFC-L2740DW?
- Leave the printer on for about 10 minutes after printing so the inside can cool, then open the front cover.
- Pull out the drum and toner assembly by its handle.
- Push down the green lock lever on the drum and lift the toner cartridge out.
- Unpack the new TN660 or TN630, rock it gently side to side a few times, and pull off the protective cover.
- Push the new cartridge into the drum until it locks; the green lever lifts by itself.
- Clean the corona wire by sliding the green tab on the drum left and right a few times, then return it to its home position.
- Slide the assembly back into the printer and close the front cover.
When you replace the drum itself, reset the drum counter afterward; our Brother drum reset guide walks through it.
Which Other Printers Use TN630 and TN660?
The same toner and DR630 drum fit the HL-L2300D, HL-L2320D, HL-L2340DW, HL-L2360DW and HL-L2380DW, the DCP-L2520DW and DCP-L2540DW, and the MFC-L2680W, MFC-L2685DW, MFC-L2700DW, MFC-L2705DW, MFC-L2707DW and MFC-L2720DW. Our TN660 explainer has the full list.
What MFC-L2740DW owners ask
These are the questions that come up most for this printer on retailer Q&A pages, manufacturer support pages and owner reviews, answered in our words.
Is the drum part of the toner cartridge?
No. The DR630 drum is a separate unit that holds the toner cartridge. You replace the toner several times (about every 2,600 pages with a TN660) before the drum is due at about 12,000 pages.
How many pages does the toner in the box print?
About 700. Brother ships the MFC-L2740DW with a reduced-capacity starter cartridge, so the first replacement comes sooner than the TN660 rating suggests.
Why does my printer keep dropping off Wi-Fi?
This is the most common owner complaint. Updating the firmware, giving the printer a fixed IP address (a DHCP reservation in your router) and power-cycling the router usually helps; if it keeps happening, the Ethernet port is the dependable fix.
I bought an MFC-L2740DW outside the US. Does it take TN660?
Not necessarily. UK and European versions of the MFC-L2740DW use TN-2310 and TN-2320 toner with a DR-2300 drum. Buy by the numbers printed on your existing cartridge.
MFC-L2740DW quirks worth knowing
- The toner and drum are separate, so budget for a DR630 roughly every 12,000 pages.
- TechRadar found the 2.7-inch touchscreen small and fiddly, and owners describe some menus (like scan-to-email setup) as hard to find.
- The 35-page document feeder can scan both sides of a page in one pass, which is uncommon at this size.
- It is discontinued; replacement toner and drums remain easy to find because the TN660 family covers many Brother models.
