MX521de

Sold as the streamlined sibling of the MX521ADE, the Lexmark MX521DE covers the same essential MFP ground — print, copy, scan, fax — on the shared 561H toner platform at a leaner configuration point. Automatic duplex and network features remain, just tuned for buyers who want the core departmental toolset without the extras. If your workflow is straightforward, this is the value play of the MX line.
