Our take
The Lexmark MS510dn is a monochrome print-only model mapped by Lexmark to U.S. part 35S0300. The maker rates it up to 45 pages per minute on Letter paper, documents integrated duplex and USB/Gigabit Ethernet, and recommends 1,500 to 14,000 pages per month. Those are unusually clear workload and interface facts for a legacy office printer. Its fit is a wired queue that needs substantial output; built-in Wi-Fi is not standard and the device is discontinued.
A wired office seeking fast monochrome output, automatic duplex, and explicit monthly workload guidance..
Avoid it if color, copy or scan functions, built-in Wi-Fi, or a current-generation purchase are required, or if the offered unit cannot be checked for condition.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- Lexmark identifies part 35S0300 as the exact MS510dn model and rates it at up to 45 ppm Letter.
- Integrated duplex, USB, and Gigabit Ethernet are documented standard features.
- The 1,500–14,000 monthly recommendation helps distinguish light use from a sustained workgroup routine.
What to weigh up
- Wireless is available only through an optional print server, not as a confirmed base-model feature.
- The printer is discontinued, so current support, parts, toner, and the condition of an offer require separate checks.
- The model prints in monochrome only and has no copy, scan, or fax workflow.

What the features mean for you
A workgroup engine with a defined workload range
Lexmark recommends 1,500 to 14,000 pages per month for the MS510dn. That range helps place it against lighter personal printers and against models whose recommended volume is unknown. The 45 pages-per-minute Letter rating describes speed, not a promise that every mixed document will reach that rate. Use the monthly range to consider fit, then account separately for paper handling, service, supplies, and the condition of the particular unit being sold.
Integrated duplex makes two-sided jobs routine
The MS510dn includes integrated duplex, so the printer can turn pages without manual refeeding. For a shared queue producing policies, internal reports, or double-sided forms, that can reduce operator time and paper handling. Confirm the exact model suffix and run a test on an offered used unit, because a published duplex specification cannot establish that a specific feed path is working. The feature is standard on the documented MS510dn, unlike models that depend on an optional module.
Ethernet and USB are the standard connections
Lexmark lists USB and Gigabit Ethernet. Ethernet supports a wired shared queue, while USB suits a direct connection to an individual workstation. Wireless is supported through an optional print server, so the base MS510dn should not be ranked as a built-in Wi-Fi device. Ask the seller for the exact adapter part and proof that it is installed if wireless operation is important. The `dn` model text alone is not evidence that optional wireless hardware is present.
Keep the printer-only boundary in view
This model is for monochrome printing only. It cannot copy, scan, or fax documents, so its throughput will not replace separate office equipment when paper capture is part of the routine. That specialization may be useful when a team already has a shared scanner or MFP, because buyers can compare the printer on output, duplex, network, and workload. Do not let a high speed rating obscure the workflow requirement: functions should be chosen before output numbers.
Discontinued status changes the ownership checklist
Lexmark marks the MS510dn discontinued. The original data sheet does not say whether a marketplace unit has been maintained, what toner remains, or whether the buyer can obtain parts and driver support today. Ask for the device label, a recent print sample, the included accessories, and return conditions. Verify supplies and compatibility with the office's operating systems before comparing it with a current model. No present price, stock, or individual machine condition is implied here.
What else to compare
The Brother HL-L5100DN is rated up to 42 ppm with a recommended ceiling of 3,500 pages; HP LaserJet P4015x has a 3,000–15,000 range. Compare the published workload intervals and exact condition.
Before you buy
What monthly range does Lexmark recommend?
Lexmark recommends 1,500 to 14,000 pages per month for the exact MS510dn model.
