T642TN
Ethernet on board and a tray for extra capacity: the Lexmark T642TN was the networked, tray-expanded answer for offices growing past entry-level printing. The second tray meant less refilling during busy days, while the network interface served multiple users at once. Its engine runs on the 640H high-yield cartridge shared across the T64x family. Compatible 640H cartridges cut the cost of every page this busy printer produces.
| Cartridge | Color | Page yield |
|---|---|---|
| 640H (64015HA / 64035HA) | Black | ~21,000 pages |
