Product Overview
The Brother MFC-L3780CDW is built for small businesses and busy home offices, offering laser-quality digital color output across all functions: printing, copying, scanning, and faxing. It’s not your average inkjet – this is a wireless multi-function printer that prioritizes speed, efficiency, and reliability.
Key Features and Specifications
- Print Speed: Up to 31 pages per minute (ppm) for both black and color, making it one of the fastest in its class for document-heavy workflows.
- Scan and Copy: Single-pass duplex scanning and copying at up to 29 images per minute (ipm) black / 22 ipm color, saving time on double-sided jobs.
- Output Quality: Consistent laser-quality prints that are crisp and professional, ideal for reports, brochures, and presentations.
- Connectivity: Built-in dual-band wireless (2.4GHz/5GHz), Gigabit Ethernet, Wi-Fi Direct, USB, and compatibility with Alexa for voice-activated printing.
- Toner and Supplies: Uses Brother Genuine TN229 series (Standard, XL, or XXL yields). Includes a 2-month Refresh EZ Print Subscription trial for automatic toner delivery – opt-in only, no commitment required.
- Paper Handling: 250-sheet capacity tray, plus a 30-sheet multipurpose tray and 50-sheet duplex auto document feeder (ADF).
- Other Perks: 3.5-inch color touchscreen, mobile printing via AirPrint, Brother iPrint&Scan app, and NFC for easy setup.
At 569 bucks, it’s positioned as a premium option, backed by Brother’s reputation for durability. Dimensions are compact for an all-in-one (17.1 x 18.7 x 16.1 inches, 47.8 lbs), fitting nicely on a desk without dominating the space.
Pros
Based on the product specs and glowing customer feedback from over 668 reviews averaging 4.2 stars, here are the standout advantages of the Brother MFC-L3780CDW:
- Lightning-Fast Performance: Customers rave about the 31 ppm speed and single-pass duplex features. One reviewer said their old Canon took “two days” for a 60-page doc due to jams – this Brother handles it flawlessly and quietly.
- Effortless Setup and Connectivity: Wireless setup is a breeze, with instant AirPrint support and no app required (though the app is simple). Dual-band Wi-Fi, Ethernet, and Alexa integration make it versatile for any office.
- Laser-Quality Prints Every Time: Bright, professional color output for documents. Reviewers note it’s “pristine” and consistent, perfect for business use without photo-printer expectations.
- Reliability and Durability: Brother’s legendary build quality shines; one user had a previous MFC last 22 years. No jams, quiet operation, and robust construction mean less frustration.
- Cost-Saving Toner Options: High-yield TN229XXL cartridges and the optional Refresh subscription (with free trial) keep long-term costs low. Light users appreciate skipping the sub entirely.
- User-Friendly Interface: The touchscreen is intuitive, and features like duplex scanning save time and paper.
- Versatile for Small Teams: Handles moderate volumes with ease, overkill for personal use but ideal for shared home offices.
Cons
No printer is perfect, and while the MFC-L3780CDW scores high overall, some drawbacks emerge from reviews and specs. Here’s a balanced look at the downsides:
- High Upfront Cost: At $569, it’s pricey for light home users. One reviewer agonized over the price despite light needs but justified it for reliability – not ideal if you print sporadically.
- Not for Photo Printing: Multiple users emphasize it’s for documents, not glossy photos. Color is “bright and fast” but lacks the depth of inkjets or dedicated photo printers.
- Toner Expenses Add Up: Brother Genuine toners are reliable but not cheap. Compatible cartridges work if installed correctly, but the subscription might not suit everyone.
- Bulky for Tiny Spaces: While compact for its features, the 47.8 lb weight and size may overwhelm very small desks.
- No USB-C for Setup: One refurbished buyer noted needing a USB-B cable (old-school) for initial Wi-Fi config on Mac, a minor but annoying hiccup.
Customer Reviews Analysis
With a solid 4.2 out of 5 stars from 668 Amazon reviews, the Brother MFC-L3780CDW earns praise for ending printer nightmares. Positive feedback dominates, focusing on reliability – a rarity in the “I hate printers” club.
Top Positives: Setup is “easy as hell,” with AirPrint working instantly. Speed and silence stun users upgrading from inkjets: “So fast, so quiet… those days [of jams] are gone forever!” Color quality suits documents perfectly, and Brother’s longevity impresses – “My last Brother MFC was 22 years old!” Refurbished units arrive pristine, with crisp test prints even on cheap paper. Light users love skipping the toner sub, and iOS printing is flawless.
Common Complaints: The price stings for low-volume printing, though many say “when a printer JUST WORKS, it’s worth it.” Photo expectations lead to minor gripes, but most clarify it’s business-oriented. A few mention manual Wi-Fi tweaks without the right cable, and while compatible toners work, instructions are key. Spanish reviews echo the positives: “Muy buena compra” (great purchase).
Overall, 5-star raves like hugging the printer highlight emotional relief from reliable performance. Negatives are nitpicks compared to the “holy grail” sentiment. Packaging is bombproof, arriving ready to rock.
Frequently Asked Questions
1. How easy is setup for the Brother MFC-L3780CDW?
Extremely straightforward. Wireless connects via WPS or the touchscreen; AirPrint is instant for Apple devices. The Brother app adds mobile scanning/printing in minutes. USB setup needs a USB-B cable, but Ethernet/Wi-Fi Direct are plug-and-play. Firmware updates take ~14 minutes post-setup.
2. Is the toner subscription mandatory?

3. Can it print photos well?
It’s optimized for laser-quality documents, not photos. Colors are bright and fast for charts/brochures, but skip it for high-end photo prints – use an inkjet for that.

Yes – AirPrint, Mopria, Brother apps for iOS/Android. Wi-Fi Direct for direct printing, and Alexa integration for hands-free jobs like “Alexa, print my shopping list.”
Who Should Buy This Product
The Brother MFC-L3780CDW is ideal for:
- Small Business Owners: Needing fast color laser printing, scanning, and faxing for client docs and marketing materials.
