Our take
The Lexmark CX331adwe part 40N9070 is a compact color laser multifunction printer for a small office that wants more than print-only output. Lexmark documents color copy, scan and fax, built-in Wi-Fi, Gigabit Ethernet, automatic print duplex and a 600–2,500 page recommended monthly range. It is a narrower workload choice than its color speed and feature list may first suggest: standard paper input is 250 sheets plus a single-sheet manual feed, and the automatic document feeder scans simplex rather than turning two-sided originals in one pass. Those trade-offs help identify whether the all-in-one functions will actually improve the desk's routine.
A small shared office that needs color copies and fax with wireless or Ethernet printing at the maker's stated 600–2,500 page monthly range..
Avoid it if color is unnecessary, duplex scanning of two-sided originals is essential, or your monthly queue regularly exceeds Lexmark's stated range.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- Lexmark confirms color print, copy, scan and fax together with Wi-Fi and Gigabit Ethernet.
- Integrated duplex turns pages for two-sided printing without manual reloading.
- The 600–2,500 page recommended range and compact dimensions can suit a smaller shared office.
What to weigh up
- The standard 250-sheet input plus one-sheet manual feed is limited for long print runs.
- The ADF is simplex, so two-sided originals need another handling step for scanning.
- The 42.7-pound listed weight is substantial for a device marketed as compact, so plan a stable surface.

What the features mean for you
Choose it for the combined color workflow
Lexmark lists color printing, copying, scanning and faxing on the CX331adwe. That can replace several separate steps for a small team that needs to circulate color handouts, copy forms and send occasional faxes. A print-only color model may be simpler if those document tasks happen elsewhere, while a larger MFP may better suit an office that scans thick packets all day. The maker's recommended range is 600 to 2,500 pages per month. Treat that as a fit check against ordinary use, not a maximum and not a guarantee of what a used printer can sustain.
Automatic duplex output does not mean duplex scanning
The print engine has integrated automatic duplex, which turns pages during a double-sided print job. Lexmark identifies the scanner as a flatbed with an ADF and marks its scan path simplex. A two-sided original therefore needs to be turned and fed again rather than scanned on both faces in a single pass. For occasional forms that may be manageable; for archive batches or frequent double-sided contracts it adds labor. Keep printing and scanning requirements separate when comparing devices: this model solves automatic duplex output, but its source does not support a claim of one-pass duplex capture.
Wireless and wired network options come built in
The standard ports include Gigabit Ethernet, 802.11b/g/n wireless and USB. Ethernet is useful for a fixed office queue managed by a router or switch; Wi-Fi helps when the printer must sit where a cable run is inconvenient. Lexmark also lists a 2.8-inch touch display and mobile printing support, which can help with occasional phone or tablet jobs. Before choosing it for a managed workplace, check the organization's wireless security and driver policies. Connectivity on the model sheet does not establish that a specific secondhand machine is configured on the intended network or retains its setup credentials.
The tray sets a practical upper bound on uninterrupted jobs
The standard input capacity is 250 sheets with an additional single-sheet manual feed; output holds 100 pages. Lexmark lists no extra standard tray, so specialty media or envelopes can be fed separately and longer runs will need more frequent replenishment than a larger office MFP. The product is relatively narrow and compact for a color multifunction device, but its listed weight is 42.7 pounds. A stable table and room to open the scanner and paper paths matter. Optional feeder claims should be checked against the exact unit rather than assumed from a family name or reseller photo.
Confirm consumables and exact part before purchase
The catalog candidate identifies part 40N9070, which matches Lexmark's U.S. product page. That matters because Lexmark states replacement cartridges are designed for particular geographic regions. Confirm the model label, supply region and included cartridges on the actual unit, especially if it is used or renewed. The manufacturer page describes a one-year onsite repair warranty for its covered product context, but it does not establish transferable coverage for a secondhand offer. Check the ADF, flatbed, touch panel and fax function as part of seller due diligence. The tagged model search helps find offers; it does not report current prices or stock.
What else to compare
Choose the Lexmark CS431dw for color print-only work with a higher published monthly range, or compare the MF525dw if monochrome output and one-pass duplex scanning matter more than color.
Before you buy
Does the CX331adwe print both sides automatically?
Yes. Lexmark lists integrated automatic duplex printing for the exact 40N9070 configuration.
Can the ADF scan both sides of an original in one pass?
No. Lexmark identifies the CX331adwe ADF as simplex; two-sided originals require another pass or manual handling.
What monthly volume does Lexmark recommend?
Lexmark's U.S. specification page gives a 600 to 2,500 page recommended monthly range.
