T640n
Network connectivity defined the Lexmark T640n, a shared-office version of the classic T640 mono laser. Plugged into the LAN, it served whole departments from a compact footprint that fit easily beside a desk or in a corner. Power and toner management stayed simple thanks to the long-running 640H cartridge. Compatible 640H toner keeps a T640n fleet affordable long after the original warranty expired.
