Our take
The Lexmark CX310dn is a color laser multifunction device for a small or medium workgroup with a wired network. Lexmark lists color printing, copying and scanning, integrated duplex, Gigabit Ethernet and USB for exact part 28C0550. The rated Letter speed reaches 25 ppm in black and color, and the recommended monthly range is 500–5,000 pages. No fax function or built-in wireless is listed for this dn configuration, so a buyer should compare those requirements explicitly. Lexmark marks the product discontinued; the specifications describe the model, not any individual offer.
A small or medium workgroup that needs color print/copy/scan, automatic two-sided output and a wired network connection..
Choose another model if you need fax, standard built-in Wi-Fi, a print-only device, or a recommendation for sustained work above 5,000 pages per month.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- Lexmark documents color print, copy and scan functions in one device for a shared document routine.
- Integrated duplex supports automatic two-sided output instead of requiring manual page turning.
- The 500–5,000 recommended monthly range and Gigabit Ethernet help judge it for a wired small or medium workgroup.
What to weigh up
- Fax is not among the listed functions, so it cannot replace a fax-capable all-in-one.
- Gigabit Ethernet and USB are the standard ports; built-in wireless is not listed for the exact dn configuration.
- Lexmark marks part 28C0550 discontinued, and an older unit's condition and supplies are not established by the product page.

What the features mean for you
Three color document tasks share one device
Lexmark lists color printing, color copying and color scanning for the CX310dn. That combination can keep routine forms, marked pages and digital capture at a shared workgroup station. The model's Letter speed reaches 25 ppm in black and color, which gives a reference point for comparing it with a smaller home-office MFP. Fax is not listed among the documented functions, so a workplace that sends or receives faxes needs a separate machine or a different model. The MFP label alone should not be treated as proof of fax capability.
Integrated duplex makes two-sided output routine
Lexmark identifies integrated duplex printing on part 28C0550 and lists up to 12 pages per minute for two-sided output. The printer turns output sheets automatically, which can reduce handling when a team produces packets or recurring reports. Two-sided throughput is distinct from the 25 ppm one-sided Letter rating; compare the mode that matches the actual queue. The source establishes the design feature, not the condition of the duplex mechanism in an individual used printer. Check the exact dn label and test the path if evaluating a physical unit.
A wired network model with local USB
The U.S. page lists Gigabit Ethernet and USB 2.0 as standard ports. Ethernet supports a shared office queue where the device can connect to a switch or router, while USB offers a direct local connection. Lexmark's naming legend uses d for duplex and n for network; the separate w suffix denotes wireless. The exact CX310dn page does not list built-in Wi-Fi as a standard port, so a wireless-only room should treat Wi-Fi as unconfirmed and check the exact available configuration before purchase. Confirm network policy and host support before deployment.
Paper handling and volume fit a smaller workgroup
Lexmark lists 250-sheet standard input, a single-sheet manual feed and a 150-sheet output bin. That setup can keep ordinary paper loaded while allowing an occasional separate sheet, but it is smaller than a production printer's paper system. The recommended monthly volume is 500–5,000 pages; this is the maker's routine guidance and not a maximum duty-cycle figure. A team with a predictable moderate queue can use the range to compare the CX310dn with both personal printers and larger workgroup machines. Count actual monthly pages rather than relying on a peak-duty headline.
Discontinued status calls for an exact-unit check
Lexmark identifies part 28C0550 as a discontinued CX310dn. Its U.S. page is a useful reference for the model's capabilities, but it cannot establish the state of any seller's machine. Check the nameplate, tray and manual-feed condition, duplex path, USB and Ethernet ports, scanner surface and any service history. Ask what toner and other supplies are included and whether the return terms allow a functional check. The product specifications support the workflow comparison; they do not establish present availability, current prices or remaining life in a particular printer.
What else to compare
Compare a fax-capable color MFP if telephone fax is required, or a current wireless model if the device cannot use a wired network.
Before you buy
Does the CX310dn include fax?
Lexmark lists color printing, copying and scanning for part 28C0550; fax is not among the documented functions.
Does it print both sides automatically?
Yes. Lexmark identifies integrated duplex on the exact CX310dn configuration and gives a separate two-sided speed rating.
What monthly workload does Lexmark recommend?
Lexmark recommends 500–5,000 pages per month for the CX310dn. This guidance is distinct from a maximum duty-cycle rating.

The decision
The CX310dn fits a wired workgroup that needs color print, copy and scan with automatic duplex and a stated moderate workload range. Its lack of listed fax or Wi-Fi and discontinued status are central limits.
