Color You Can Count On

Busy workgroups get a big edge with excellent color quality, reliable paper feeding, fast print speeds up to 30 ppm in black and color, and paper-saving duplexing. Plus a tiltable operator panel with 4-line graphics display and convenient front Direct USB port make it an intelligent office partner.

Fast Start Meets High Volume

Standard paper input capacity for up to 650 sheets can grow to 3,750 sheets simply by adding three stackable drawer options—a time-saving solution for high-volume jobs or to accommodate a wide range of paper types, such as card stock or labels. With Lexmark's instant warm-up fuser, expect results in just seconds even from a cold start.

Cutting-Edge Security

From network security to user-access restrictions, you’ll be fully equipped to keep valuable data safe and sound. In addition to IPSec, SNMPv3 and 802.1x network security, the Lexmark C734dn offers an alphanumeric pad for easy PIN authentication, plus encryption and disk wiping to secure the optional hard disk.

Great Color, Great Savings

High-quality color adds impact to every impression you make. Keeps color costs in check with easy to use cost-control tools, and smart technology senses when you’re printing black-only pages and automatically conserves color toner.

Effortless IT Manageability

Network-ready and very easy to set up, plus Universal Driver support for simple deployment. On-screen custom messaging empowers uses with clear status info like “Toner Low, Call Placed.” Includes Lexmark MarkVision™ Professional software for easy remote management.
