T634DTN
Long print runs are where the T634DTN earns its keep: duplex printing, twin trays, and network connectivity paired with the fastest engine in the T630 line. Toner is the familiar 12A7360 return-program or 12A7362 standard cartridge pair shared across the whole family. High-volume departments get fewer interruptions, fewer refills, and two-sided output by default. Built for print rooms where downtime is not an option.
