Our take
The Lexmark C734dn is a discontinued color laser printer for a wired workgroup that values paper capacity and integrated duplex. Lexmark documents up to 30 pages per minute in black and color on Letter, with duplex output up to 20 sides per minute in black. Standard input totals 650 sheets from a 550-sheet main tray and 100-sheet multipurpose feeder; output is rated for 300 sheets. The model includes Ethernet that supports 1000Base-T and USB 2.0 ports. Its recommended monthly range is 1,500 to 9,200 pages. Buyers should distinguish this base C734dn from the C734dtn, which adds a lower tray.
A wired office that needs a large standard paper reserve and can verify the C734dn configuration, supplies, and software..
Skip it if you need built-in Wi-Fi, multifunction features, an active model line, or certainty that a used seller has the correct C734dn rather than a related configuration.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- Lexmark specifies integrated automatic duplex and a 650-sheet standard input for longer office queues.
- The source provides separate black and color ratings and a duplex rate for planning two-sided output.
- Ethernet and USB support a wired installation, while the 1,500–9,200 page range provides documented workload guidance.
What to weigh up
- Lexmark marks the C734dn discontinued, so supply availability, repairs, and driver compatibility need checking.
- The saved material does not establish built-in wireless for this exact configuration.
- A listing for the C734dtn or an added lower tray is not evidence that the base C734dn includes that accessory.

What the features mean for you
Color print-only output for a wired team
Lexmark identifies the C734dn as a color laser printer, not a copier, scanner, or fax machine. That narrower role can be useful when an office already owns separate document equipment and wants a shared color output queue. The exact suffix is important: Lexmark distinguishes this base C734dn from the C734dtn, which has an additional lower tray. A generic family listing can obscure that package difference. Choose the C734dn because the print-only workflow and wired placement fit the desk, then verify the model label and tray arrangement on any used device before comparing it with more recent color printers.
Rated color speed and built-in duplex
Lexmark lists up to 30 pages per minute in both black and color on Letter paper and up to 20 duplex sides per minute in black. Integrated automatic duplex handles page turning for two-sided output, which can reduce paper handling for regular reports. A color queue may not reach its rated rate on every complex page, and the source is not a test of a particular unit. The duplex figure is useful context because it differs from the maximum one-sided rating. If a team prints mostly occasional forms, the capacity and speed may exceed its routine; regular shared jobs make those features more relevant.
A large standard tray is the main practical advantage
The standard input totals 650 sheets: 550 in the main tray and 100 in the multipurpose feeder. Lexmark rates output for 300 sheets. This arrangement can keep more paper ready than a compact color printer and can allow a separate stock in the multipurpose path. It does not mean the printer has the optional lower drawer installed. The C734dtn is the related configuration with an extra tray, so buyers should not pay for or plan around that capacity unless it is physically included. Inspect all trays and test pickup on the actual unit, especially if it has been in storage.
Ethernet and USB are documented; wireless is not
Lexmark lists an Ethernet interface supporting 1000Base-T, USB 2.0 Type B, and front USB 2.0 Type A. The saved source does not establish built-in Wi-Fi for the C734dn, so this profile does not qualify it for a built-in wireless requirement. Wired Ethernet provides a clear shared-network path; USB can serve a direct host or the documented front-port workflow. A model name ending in dn should not be expanded into a wireless claim. Before purchase, check the rear port panel and the compatibility of the intended computers with the available driver support.
Monthly guidance does not settle remaining service life
Lexmark recommends a monthly range of 1,500 to 9,200 pages. This range is more useful for workload planning than the maximum duty cycle sometimes repeated in reseller material, but it does not establish prior usage or the remaining life of a particular machine. Lexmark marks the model discontinued. A buyer should compare the expected queue with the published recommendation and independently confirm toner, drums, parts, repair options, and software support. The historical ASIN B002AU5P08 is not considered an exact current offer because the saved Amazon page returned an internal error; the purchase link searches by exact model and part number.
Check the C734dn suffix before buying
The C734dn has a documented 550-sheet main tray plus a 100-sheet multipurpose feeder. The C734dtn adds a lower tray, so the suffix can change the setup a buyer receives. Ask for a photo of the model plate and the paper drawers, and confirm that the seller means 25C0351 if that is the configuration intended. Test a color page, duplex printing, network access, and all feed paths. This review describes Lexmark's specifications rather than an inspected unit. The product is most plausible for an office with a wired network and a real need for capacity that can handle used equipment due diligence.
What else to compare
Compare the Dell C2660dn for a 400-sheet configuration with a 750–3,500 page recommendation, or the CS510dte when its included 900-sheet arrangement fits better.
Before you buy
Is the C734dn a multifunction printer?
No. Lexmark identifies the C734dn as a color printer; copying, scanning, and fax are not part of this configuration.
What is the difference between C734dn and C734dtn?
The C734dtn adds a lower tray. Confirm the suffix and included drawer rather than assuming the accessory is present.
Does it have a published workload range?
Lexmark lists a recommended monthly range of 1,500 to 9,200 pages for the C734dn.

The decision
The C734dn is defined by its 650-sheet standard input, integrated duplex, and wired color output. Its discontinued status and the C734dtn tray distinction make exact-unit verification essential.
