X644EF
Fax capability and Ethernet sharing distinguished the Lexmark X644EF, the MFP that gave departments a single machine for printing, copying, scanning, and faxing. Consolidation cut equipment costs and freed up office space, while networked operation served everyone. Its T644-class engine runs on the 640H high-yield cartridge shared with the whole family. Compatible 640H cartridges keep this multifunction workhorse's operating costs firmly in check.
