The multiple award-winning Brother Workhorse Series HL-L6400DW monochrome laser printer delivers a low total cost of ownership, advanced security features, scalable paper handling, and productivity enhancing features for mid to large-sized workgroups with higher print volumes.

Business-durable for mid to large-sized workgroups with higher print volumes

Business-enhancing features and business-durable design – to meet the needs of your busy office.

Part of the Keypoint Intelligence - Buyers Lab (BLI) 2017 Monochrome Printer/MFP Line of the Year and BLI Summer 2016 Pick Award winner for Outstanding Printer for Mid-Size Workgroups, the HL-L6400DW offers extremely high reliability offering business-centric features and functionality to help optimize workflow, enhance productivity, and improve the bottom line. This high-performance printer keeps moving at the pace of your business with an impressive print speed of up to 52 pages per minute. Plus, the HL-L6400DW produces professional reports, spreadsheets, correspondence, and other important business documents with crisp text and excellent graphics.

“Designed to keep workers productive, the HL-L6400 Series offers exceptional reliability and a robust fuser design that lets the printer continue to crank out pages at full speed, even at peak volumes, without needing to slow down to cool the fuser,” said BLI Test Technician Rich Holloway.

Included super high-yield toner cartridge for built-in value 1

Low total cost of ownership helps maximize your budget

Print professional business documents and enjoy a low total cost of ownership - with the included super high-yield 12,000-page toner cartridge 1 for built-in value for your business. For even lower cost printing, use the ultra-high yield 20,000-page 1 replacement cartridge. Also, two-sided (duplex) printing means less paper use – and helps save paper and money. Environmentally friendly, the HL-L6400DW is ENERGY STAR® Certified and offers a Deep Sleep Mode that only uses 1.3 watts of power when not in use.

Optional add-on tower tray and mailbox enable customized workflow solutions and greater input and output capacity

High maximum paper capacity helps minimize user intervention

The HL-L6400DW comes with a 520-sheet capacity paper tray that can hold more than a ream of paper for fewer refills, and is adjustable for letter or legal-size paper. A 50-sheet capacity multi-purpose tray is useful for printing envelopes (up to 10) and on alternative media types. Additional optional paper trays are available in 250-sheet or 520-sheet capacities, enabling users to configure the printer with multiple trays in a way that best meets their application requirements – up to 1,610 sheet total capacity.

According to BLI Test Technician Rich Holloway, “And with a maximum paper capacity of 2,650 sheets, the HL-L6400DW not only offers a robust feature set, but also requires minimum intervention to keep up with their needs.”

Alternatively, a tower tray option that includes four 520-sheet trays and a stabilizer transforms the printer into a floor standing printer. This versatile option is ideal for workgroups that need multiple trays to customize their workflow and allows for new workflow improvements, including storing different media in each tray.

Plus, an add-on mailbox/sorter/stacker option is useful for workgroups that are looking to assign bins to various users, sort output into separate bins, or require additional output capacity – up to 1,050 total sheets.

Download and install BRAdmin Professional software 3 to give administrators the ability to configure many of the network and printer functions via an Explorer-style window. You can log the status and activity of the HL-L6400DW, as well as other Brother devices on your network.

“The HL-L6400DW Series give workers the ability to print quickly and easily from their mobile device, a must-have feature in organizations today,” said Marlene Orr, Director of Printer and MFP Analysis for Keypoint Intelligence – Buyers Lab.

Workgroup members and office visitors will appreciate the convenience of printing wirelessly from a compatible Apple® iOS, Android™, Kindle Fire™, or Windows® Phone mobile device. Print via 4 : AirPrint®, Google Cloud Print™ 2.0, Brother iPrint&Scan (free downloadable app), Mopria®, or Wi-Fi Direct®. Near Field Communication (NFC) 5 capability is also available, which automatically establishes a direct connection between your NFC-enabled smartphone or tablet and the HL-L6400DW, so users can print without having to connect to a network or enter any login credentials.

Plus, a USB Host, located on the back of the machine, is ideal for third-party card reader support 6 .
