Our take
Lexmark's CX510de is a color laser MFP aimed at a wired office that needs copy, scan and fax in addition to printing. Lexmark lists output up to 32 pages per minute, integrated print duplex, a reversing duplex ADF and a 1,500–7,000-page recommended monthly range. That combination makes the model more useful for two-sided paper intake than a simplex-feeder MFP. The main compromises are its discontinued status, lack of standard Wi-Fi and a 250-sheet standard input tray.
A wired small-to-medium workgroup that needs color faxing, automatic duplex and two-sided document capture..
Look elsewhere if built-in Wi-Fi, a larger standard paper supply, or a current manufacturer-supported model is essential to your buying decision.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- The reversing duplex ADF is documented for scanning two-sided originals without manually turning each sheet.
- Lexmark lists integrated duplex printing and color output up to 32 ppm in black and color.
- A 1,500–7,000-page monthly recommendation and Gigabit Ethernet suit a shared wired workgroup.
What to weigh up
- Lexmark marks the CX510de discontinued, so check supplies, service options and driver compatibility before relying on it.
- Standard input is 250+1 sheets; higher capacity requires optional trays.
- The exact U.S. page lists USB and Ethernet but not built-in Wi-Fi.

What the features mean for you
Copy, scan and fax share the same color device
Lexmark lists color printing, color copying, color scanning and color fax for this exact CX510de configuration. That breadth can consolidate an office's paper workflows, especially where incoming forms are copied, sent or digitized at the printer. The model page maps U.S. part 28E0500 to the CX510de; the identity matters because suffixes in a product family can change hardware. A print-only device is a better fit when the other functions would sit unused, but this MFP makes its strongest case when the shared station handles originals as well as output.
Duplex scanning changes how originals are handled
The CX510de's 50-sheet ADF is a reversing duplex design, and Lexmark documents duplex scan speeds of up to 13 or 14 sides per minute depending on paper size. That can reduce manual handling when an office digitizes two-sided packets. It is a distinct advantage over a feeder that only scans one side at a time. The ADF still has a finite stack capacity, so very large jobs require reloading. Check that the reversing mechanism works on an offered used unit rather than assuming every feature remains functional.
A recommendation range helps place its workload
Lexmark recommends 1,500 to 7,000 pages per month and rates black and color output up to 32 pages per minute. The range helps compare this model with compact home-office MFPs and heavier enterprise printers. It is not a guarantee of speed for every file or of condition on a used device. Use expected monthly pages and color job mix to decide whether the range is sensible. A small team with regular color documents may use this capacity; a substantially larger operation should compare a higher recommendation and larger standard paper capacity.
Integrated duplex and wired ports are the clear print path
Lexmark specifies integrated two-sided printing and Gigabit Ethernet, along with USB. The duplexer can remove a manual page-turning step for reports, while Ethernet suits a fixed shared office queue. Standard input is 250+1 sheets; optional trays increase capacity, but those are additions rather than part of the base configuration. The U.S. page offers wireless as an optional network port, not a built-in feature, so this profile does not treat Wi-Fi as standard. Confirm installed accessories and paper trays on a particular unit.
Discontinued status makes lifecycle checks practical
Lexmark marks the CX510de discontinued. That does not decide whether an individual unit is a useful purchase, but it makes supplies, service availability, supported operating systems and return terms especially important. The rated performance describes the original design, not the state of a particular machine. Before choosing it for a business, confirm the 28E0500 identity, test the ADF and duplex path on the actual unit, and verify that the required connections and consumables remain workable. The Amazon link is an exact-model search, not a validated listing.
What else to compare
Choose a current supported model when lifecycle assurance matters, or a Wi-Fi-equipped color MFP when wireless networking is a firm requirement.
Before you buy
Can the CX510de scan both sides in the feeder?
Lexmark specifies a reversing duplex ADF and duplex scan speeds for the CX510de, so it supports two-sided document capture.
Does it have automatic two-sided printing?
Yes. Lexmark lists integrated duplex printing for the CX510de, separate from its duplex ADF scanning capability.
Is the CX510de a current Lexmark model?
Lexmark marks the CX510de discontinued; check current supplies, service options, drivers and the condition of any offered unit.
Where can I check the current price?

The decision
The CX510de fits a wired office that uses color fax, automatic duplex output and duplex scanning. Its discontinued status and standard paper capacity deserve equal attention.
