AI Verdict
A 19 ppm color laser all-in-one with 250-sheet capacity and 50-sheet ADF for small offices needing document printing and scanning.
This printer is a situational fit for small offices that prioritize document handling and connectivity over raw speed or photo quality. Its 19 ppm speed and 250-sheet capacity are adequate for moderate workloads, but the high color toner cost is a consideration for frequent color printing.
If you need faster speeds or lower color printing costs, look for models with higher ppm ratings or more economical toner systems.

What Buyers Say
Users frequently point out that while this printer delivers crisp text and clear graphics, its color photo output isn't its strong suit, with muted colors. The 19 ppm print speed is considered adequate for most office tasks, but it's not a speed demon. Many appreciate the dual-band Wi-Fi and mobile printing options, making it easy for multiple users to connect. However, the 16.4 cents per page color toner cost is a recurring concern for those who print a lot in color.
“Honestly, I got this for my small business and it prints documents fine, but if you're thinking of printing anything with actual photos, forget it, the colors look kinda dull and the toner is expensive if you use color a lot. But for invoices and stuff, it's okay.”
Common Praise
- Text comes out crisp and colors stay vibrant for charts and reports.
- The 50-sheet automatic document feeder is a lifesaver for processing stacks of pages.
- Wireless setup is straightforward and connectivity remains reliable once connected.
- The 3.5-inch color touchscreen with customizable shortcuts is intuitive to use.
- The Brother Mobile Connect app provides complete control from a phone, including toner level monitoring.
- The printer's build feels sturdy and durable, suitable for office environments.
Common Complaints
- Color output is not competitive with professional photo printers, showing muted colors and limited gamut.
- The 19 ppm print speed is not blazing fast, and there's a noticeable warm-up time for the first page.
- The printer can be louder than inkjet models during heavy use, which is noticeable in quiet rooms.
- Some users have experienced poor customer service when issues arise.
- High color toner costs make frequent color printing expensive.
- At 44 pounds, it's a heavy machine that requires a dedicated, sturdy space [cite: Product Data].
Ownership Tips
- The automatic document feeder really does save time when scanning multi-page contracts, you just load and walk away.
- Wireless connectivity is surprisingly stable, even with multiple devices connected over 5GHz.
- Monitoring toner levels through the mobile app is genuinely useful for avoiding unexpected outages.
- The printer's weight means it's not something you'll be moving around often, so pick its spot carefully [cite: Product Data].
- While it prints quickly enough for daily tasks, don't expect instant prints, especially for the first page.
Frequently Asked Questions
Does this printer support duplex scanning?
The product description and user reviews confirm automatic duplex printing, but not explicitly duplex scanning for the ADF. The ADF scans at 29/22 ipm (black/color). Some variants might have duplex ADF scanning, but it's not a universal feature for this specific model.
What are the typical toner costs for this model?
Monochrome prints cost approximately 2.5 cents per page, while color prints are about 16.4 cents per page.
Can I print from my phone or tablet?
Yes, it supports mobile printing through the Brother Mobile Connect app, AirPrint, and Mopria, utilizing its dual-band wireless connectivity.
Is this printer suitable for printing photos?
No, it is not ideal for photo printing. User feedback indicates muted colors and a limited color gamut compared to dedicated photo printers.
What is the paper capacity?
It includes a 250-sheet adjustable paper tray and a 50-sheet automatic document feeder.
Does it have a touchscreen?
Yes, it features a 3.5-inch color touchscreen with customizable shortcuts for easier navigation.
Is it noisy during operation?
Laser printers are generally louder than inkjets during heavy use. Some owners have noted the sound is noticeable in very quiet rooms.
Buying Guide
When looking at a laser printer like this, you're buying for speed and consistency with documents, not photo quality. Pay attention to the print speed (ppm) for how fast it spits out pages, and the paper capacity so you're not constantly refilling. Also, check the cost per page for toner, especially for color, because that's where the real long-term expense often hides.
Print Speed (ppm)
This tells you how many pages per minute the printer can produce. A higher ppm means less waiting, which is crucial for busy offices or when printing large reports.
Automatic Document Feeder (ADF)
An ADF lets you load a stack of papers for scanning, copying, or faxing, instead of placing each page individually. It's like having an assistant for multi-page tasks, saving you a ton of time.
Duplex Printing
This feature automatically prints on both sides of a page. It saves paper, reduces clutter, and makes your documents look more professional without you having to manually flip pages.
Connectivity (Dual-band Wireless, Wi-Fi Direct)
This determines how easily your devices can talk to the printer. Dual-band Wi-Fi offers more stable connections, and Wi-Fi Direct lets you print from devices without needing a router, making it super flexible for different setups.
Alternatives
If this model doesn't fit, search for color laser all-in-one printers with higher print speeds, lower color toner costs, or expandable paper trays for heavier workloads.
