Who it fits

Key specs explained for this model

Print Speed: 19 ppm

This speed indicates the printer produces nineteen pages per minute. You get consistent output for color documents without significant delays between sheets. This rate suits small teams that need regular reports or marketing materials. It is slower than high-volume office machines but adequate for moderate daily workloads. Compare this figure to faster models if you print hundreds of pages daily.

Connectivity: Wireless, USB 2.0, Wi-Fi Direct

You can connect the printer to your office network via dual-band wireless or plug it directly into a computer using USB 2.0. Wi-Fi Direct allows devices to print without a router, which is useful in temporary setups. This flexibility ensures multiple users in your space can send jobs easily. It fits environments with mixed wired and wireless devices.

Print Output: Color

This machine uses toner to produce full-color prints, charts, and graphics. You benefit from vibrant output for presentations or client documents that require visual impact. Color laser technology ensures text remains sharp while images display accurately. If you only need black and white text, this feature may be unnecessary. It is ideal for businesses requiring professional colored materials.

Duplex Printing: Automatic

The printer flips pages automatically to print on both sides. You save paper and reduce costs for two-sided documents like contracts or booklets. This feature eliminates the need to manually reload sheets, speeding up your workflow. It is a standard requirement for modern office efficiency. Compare this to models that only offer manual duplexing, which are slower and prone to errors.

Physical Design And Build Quality

According to the listing, the Brother MFC-L3720CDW measures 17.5 inches wide, 16.1 inches deep, and 15.8 inches tall. It weighs 44 pounds. These dimensions place it in the standard category for office multifunction devices. You will need a desk or dedicated cart with sufficient surface area to accommodate its footprint. The substantial weight suggests a stable internal frame, which helps keep the unit steady during high-speed printing cycles. This stability is useful if you plan to print frequently without worrying about the machine shifting during operation.

The exterior finish is white, offering a neutral look that blends into most professional environments. The control panel features a 3.5-inch color touchscreen. This display provides direct access to cloud services and includes 48 customizable shortcuts. You can manage settings and start jobs without relying on a connected computer. The layout keeps essential functions within easy reach, reducing the time spent navigating complex menus.

Connectivity options include dual-band wireless networking and USB 2.0. Wi-Fi Direct allows devices to connect without a router. This flexibility means you can position the printer where power and network access are available, rather than being tethered to a specific corner. The design prioritizes functionality over compactness, ensuring all necessary components fit within the standard chassis. You get a robust machine built for daily use.

Setup And Daily Use Guide

Setting up the Brother MFC-L3720CDW involves connecting it to your network. The listing specifies dual-band wireless networking at 2.4GHz and 5GHz. You can also use the USB 2.0 interface for a direct computer link. Wi-Fi Direct allows devices to connect without a router. This flexibility helps you place the unit in various office spots.

Daily operation relies on the 3.5-inch color touchscreen. The display offers forty-eight customizable shortcuts. You can access cloud services like Google Drive, Dropbox, and OneNote directly from the screen. This reduces the need to switch between applications on your computer. The interface also provides remote access capabilities. You can monitor toner levels and manage the printer from a mobile device using the companion app.

The 50-sheet auto document feeder handles multi-page scanning and copying tasks. It works with automatic duplex scanning. This feature flips pages for two-sided documents without manual intervention. The 250-sheet adjustable paper tray holds standard stock. Automatic duplex printing supports two-sided output for reports. You load paper once, and the machine handles the rest. This workflow minimizes paper waste and saves time. The combination of wireless connectivity, cloud integration, and automated features creates a streamlined environment for busy teams. You focus on content while the hardware manages the physical tasks.

Before You Buy This Printer

Before purchasing the Brother MFC-L3720CDW, verify your office network supports dual-band Wi-Fi at 2.4GHz and 5GHz. This ensures stable connectivity for all users. Check if your team needs fax capabilities, as this model includes a built-in fax function alongside printing, scanning, and copying. Confirm your computer operating systems are compatible with the provided USB 2.0 interface and companion app for mobile management. You should also consider toner supply. The listing offers variations with high-yield black and color toner bundles, which may reduce future ordering needs. Ensure your workspace can accommodate its 17.5-inch width and 44-pound weight. This device fits well among other all-in-one laser printers if you require color output and automatic duplexing. It suits busy environments needing reliable, high-volume document handling without frequent interruptions.
