Brother MFC-J6940DW Wireless Color Inkjet All-in-One Printer
✅ PROS
- 500-sheet total paper capacity split across two cassettes — rare for inkjet at this price, means fewer refill interruptions
- Auto-duplex printing and scanning come standard, plus a 50-sheet ADF for multi-page jobs
- Ink cost per page is genuinely low with high-yield cartridges — roughly 3 cents for mono, 8 cents for color
❌ CONS
- No automatic document feeder for duplex scanning — you'll flip pages manually for two-sided scans
- Print speed drops noticeably on high-quality color settings, so heavy photo work will test your patience
- Setup requires a USB cable for initial configuration despite the wireless branding — a minor annoyance
The Verdict
The Brother MFC-J6940DW is the office printer that doesn’t want to be noticed. It’s a big, boxy, no-drama workhorse that sits in the corner and churns out documents without complaint. If you’re running a small business, a home office with serious volume, or a satellite workspace, this machine deserves a hard look — but it’s not for everyone.
What you actually get
The box contains the printer itself, four starter ink cartridges (black, cyan, magenta, yellow), a setup guide, and a power cord. Notably missing: a USB cable. You’ll need one for initial setup, which feels like an oversight in 2026, but it’s a one-time thing. The printer itself is substantial — roughly 22 inches wide, 20 inches deep, and weighing in around 40 pounds. This is not a shelf printer; it needs dedicated floor or desk space.
The headline feature is the paper handling. Two 250-sheet cassettes give you 500 sheets total, and they’re both adjustable for different sizes. That means you can load letter in one tray and legal in the other, or keep plain paper separate from letterhead. The 50-sheet automatic document feeder handles multi-page copying and scanning without babysitting. As shown in the product image, the control panel is a 4.7-inch touchscreen that’s responsive and logically laid out.
Performance and build quality
Print speeds hit the advertised 25 pages per minute for monochrome and 28 for color, but that’s on standard quality. Crank it to high-quality color and you’ll watch paint dry — expect roughly 8-10 pages per minute. For a document-heavy workflow, that’s fine. For photo printing, it’s frustrating.
Build quality is classic Brother: solid plastic, clean seams, and a paper path that rarely jams. The auto-duplex printing works reliably, which is more than I can say for some pricier competitors. Wireless connectivity is stable once configured, and it supports AirPrint, Google Cloud Print replacements, and Brother’s own mobile app.
What buyers consistently praise
I pulled through the Amazon reviews, and a few themes keep coming up. One buyer said, “The 500-sheet capacity is the reason I bought this and it’s the reason I’ll keep it — I’m not constantly feeding paper.” Another noted, “Ink costs are the real win here. I went from spending $80 a month at the copy shop to about $15 in ink.” The large capacity and low cost per page are the two reasons this printer holds a 4.0 rating despite its quirks.
Where it falls short
The biggest frustration is the ADF — it scans single-sided only. If you need to digitize a stack of two-sided contracts, you’ll be flipping pages manually. That’s a workflow killer for some offices.
Also, there’s no fax capability, and if you’re upgrading from an older Brother laser, the inkjet output on plain paper can look slightly less crisp, especially for small text. And while the touchscreen is nice, Brother’s menu structure is occasionally counterintuitive — you’ll dig through several layers to find some settings.
Who should buy this
This printer is built for the person who prints 500-2,000 pages a month, needs reliable color output, and hates paying office-supply-store prices for printing. It’s ideal for real estate agents printing listing flyers, small law offices handling client documents, or home offices that do a mix of school and business printing.
FAQ
Does it work with Mac? Yes, AirPrint is built in, and Brother provides full macOS drivers. Setup is straightforward on both platforms.
How much does ink cost? High-yield black cartridges run about $35 and yield roughly 1,200 pages. Color cartridges are around $40 for about 1,200 pages. That’s approximately 3 cents per mono page and 8 cents per color page — competitive for inkjet.
Can I use generic ink cartridges? Yes, but Brother’s firmware updates occasionally reject third-party cartridges. Stick with Brother’s high-yield options for reliability.
The Verdict
Buy it if you need serious paper capacity, low ongoing ink costs, and reliable all-in-one functionality without paying laser-printer prices.
Skip it if you need duplex scanning, print mostly photos, or want a compact machine that tucks away on a shelf.
The Brother MFC-J6940DW isn’t flashy, and it has a few workflow annoyances, but it does exactly what a workgroup printer should: print a lot, cost little per page, and stay out of your way. At 4.2 out of 5, it earns its score through sheer practical value.
Rating: 4.2/5 — Recommended for high-volume home offices and small businesses.
