X646ef
The Lexmark X646ef was the everything-included MFP: fax, Ethernet, and the fastest engine of the family in one floor-standing package. Departments that consolidated everything onto one machine eliminated three other devices and their maintenance headaches. They lean hard on the 640H high-yield cartridge to keep it all running. Compatible 640H toner keeps the cost of all that consolidated output surprisingly low.
