Overview

In a home office or front desk, the Lexmark all-in-one prints, copies, scans and faxes in black and white, with a document feeder for multi-page scans. It connects by Ethernet or USB, with wireless as an add-on.

Fax plus fast duplex printing in a compact body covers most small office paperwork. The feeder scans single-sided only. Speed figures differ between the specs and description.

Who it's for

Front desks and home offices with fax needs suit the all-in-one. Wireless users should choose the Wi-Fi model.
