Our take
Ricoh's U.S. brochure identifies the Aficio SP 3400N as a monochrome laser printer with standard Ethernet and USB 2.0, a 30-page-per-minute Letter rating, and a 250-sheet tray plus 50-sheet bypass. It is a print-only model. The exact suffix matters for duplex: Ricoh lists manual duplex for the SP 3400N and standard automatic duplex for the related SP 3410DN. The brochure specifies 120 V, which anchors this model evidence to the U.S. configuration. A recommended monthly page range was not stated in the material reviewed.
A wired desktop or small-office mono print queue that values Ethernet and USB but can accept manual page turning..
Choose another configuration if automatic duplex, copy or scan functions, wireless networking, or a documented monthly workload range is required.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- Ricoh documents standard Ethernet and USB 2.0 on the SP 3400N.
- A 30 ppm Letter rating and 250-sheet tray plus 50-sheet bypass clarify its intended desktop-office role.
- The U.S. brochure explicitly separates the N model's manual duplex from the DN model's automatic duplex.
What to weigh up
- Two-sided printing is manual on the exact SP 3400N; automatic duplex belongs to SP 3410DN.
- It is print only and does not provide copy, scan, or fax functions.
- The reviewed brochure does not establish a recommended monthly volume or built-in wireless connection.

What the features mean for you
A single-function black-and-white printer
Ricoh presents the SP 3400N as a desktop black-and-white laser printer for home offices and small businesses. It does not consolidate copy, scan, or fax functions, so a separate device is needed for document capture. This straightforward role can be useful where an office already has a multifunction copier and wants a separate networked queue. The exact model code is important because similar Aficio devices carry extra letters for duplex or fax capabilities. Use the 3400N description rather than a broad family listing when checking a particular unit.
Manual duplex is the key variant distinction
Ricoh's brochure directly states that duplexing is manual on the SP 3400N and automatic on the SP 3410DN. This distinction is central to choosing between the two versions. The 3400N can still support two-sided jobs, but the user must handle sheets between sides. If duplex work is frequent, the DN configuration is a more natural comparison, provided the exact offered device and accessories match. Do not count the 3400N as an automatic-duplex printer because the closely named family includes another model that does have that mechanism.
Wired access and media capacity
Ricoh lists Ethernet and USB 2.0 as standard interfaces and specifies a 250-sheet main tray with a 50-sheet bypass tray. An optional paper-feed unit can raise capacity, but it is not included in the base configuration by default. The wired connection can serve a small office with an Ethernet drop, while USB allows a direct computer link. Built-in Wi-Fi is not listed in the brochure. Check any power-line Ethernet adapter or other accessory separately because a related accessory does not change what comes standard with the printer.
Rated speed and monthly planning
Ricoh rates the SP 3400N at up to 30 Letter pages per minute and lists a first print time as fast as eight seconds. The brochure also notes a 20-second warm-up figure and supports paper sizes up to 8.5 by 14 inches. These are manufacturer conditions that help compare the device, not a guarantee for every document or every used unit. A comparable recommended monthly range does not appear in the sheet reviewed. Buyers should therefore match the machine to their workload using documented guidance from another source or avoid a precise volume claim.
Power and current-unit checks
The Ricoh U.S. brochure specifies 120 V at 60 Hz, a useful detail when distinguishing a U.S. model from a regional variant. It also identifies the 406451 part number and an all-in-one print cartridge family. That original description cannot show which cartridge is installed now, how much toner remains, or whether a refurbished unit meets a buyer's condition expectations. Check the model label, Ethernet and USB ports, tray and bypass, manual duplex behavior, consumable availability, counter, driver fit, and return terms before making a decision.
Who should shortlist the SP 3400N
The SP 3400N can fit a small wired office wanting monochrome output, Ethernet and USB, and a rated pace of 30 pages per minute. It is a less natural choice if automatic duplex or document functions are required. If the candidate listing suggests a 3410DN or another variant, compare the label and included duplex hardware before using this profile. The finder keeps the 3400N's manual duplex separate from automatic page turning. No monthly recommendation is assigned from the sources reviewed, and this assessment does not claim hands-on testing or current offer availability.
What else to compare
The Brother HL-L2350DW adds built-in Wi-Fi and automatic duplex for lower-volume use; the Lexmark E260d keeps automatic duplex but uses direct USB or parallel connections.
