Our take
OKI's U.S. product sheet maps part 43641801 to the 120 V B2400. The exact B2400 is a monochrome LED print-only device rated up to 21 ppm with USB and parallel interfaces. OKI identifies the Ethernet-equipped B2400n as a separate model, so networking should not be transferred by family name. The LED versus laser explainer describes OKI's LED printhead technology; the category includes this office printer while preserving the mechanism accurately. The reviewed sheet does not establish duplex support or a recommended monthly workload.
A direct USB or parallel workstation that needs monochrome printing and does not depend on network sharing, automatic duplex, or MFP functions..
It is not suitable if you need copy, scan, fax, Ethernet or Wi-Fi sharing, confirmed automatic duplex, or a documented monthly page range.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- OKI maps the exact 43641801 U.S. part to a 120 V B2400 configuration.
- The maker lists monochrome output up to 21 ppm and USB plus parallel interfaces.
- The review keeps the Ethernet B2400n distinct from this base B2400.
What to weigh up
- It is print-only and cannot replace an all-in-one's copy, scan, or fax workflow.
- The reviewed exact-part sheet does not establish duplex printing or a recommended monthly range.
- Current supply, driver, and used-unit condition are unknown for this older model.

What the features mean for you
How does part 43641801 identify the U.S. model?
OKI Data Americas maps part 43641801 to the 120 V B2400. Keeping the part number in the product name makes it easier to separate this U.S. configuration from regional versions and the B2400n network variant. Historical listing text alone is not proof that a present offer has this specific label. Ask for a clear nameplate photograph and confirm voltage before ordering. A source establishes the model configuration; it cannot establish that a seller's unit still has its original board, accessories, or operating condition.
What kind of print work does the B2400 cover?
The OKI sheet describes the B2400 as a monochrome printer rated up to 21 pages per minute. It has no listed copy, scan, or fax functions, so the role is narrower than an MFP. The rating is useful as a manufacturer specification for comparing intended output, but it is not measured performance for an aging unit or a guarantee for a mixed job queue. This model makes most sense when another device already handles originals and color, and the need is a simple black-print path at one workstation.
Which connection does the base B2400 include?
OKI lists USB and parallel for the exact B2400 part. The Ethernet-equipped B2400n is separately named, and its network port should not be attributed to the base model. The interfaces therefore fit a direct workstation or compatible older parallel setup, not a standard shared Ethernet queue. The reviewed source does not confirm built-in wireless for the B2400. If office sharing is required, keep that as a must-have and compare a model with documented Ethernet or Wi-Fi rather than planning around an unverified accessory.
Can it turn pages automatically or guide monthly volume?
The reviewed B2400 sheet does not establish automatic or manual duplex printing, so neither matching value is marked true. A second source number of 15,000 pages describes the monthly maximum duty cycle, not OKI's recommended routine monthly volume. Those are separate questions: a maximum rating should not be used as advice about sustained monthly use. The reviewed sources do not establish a recommended monthly workload range for the B2400; a maximum duty-cycle figure is not that recommendation. If regular duplex jobs or a numeric workload ceiling matter, a printer with explicit documentation will make a safer comparison.
What should a buyer verify on a legacy unit?
The product sheet describes the original configuration and does not report the page count, LED head condition, toner level, roller wear, firmware, or compatibility of a particular offer. Confirm the model label and the intended USB or parallel host before purchase. Ask the seller for a sample page, included supplies, return conditions, and any driver installation details. This is especially relevant because B2400, B2400n, and regional packages have distinct part numbers and ports. No current offer status, price, repair support, or consumable stock is inferred from the historical manufacturer literature.
What else to compare
Choose the B2400n only if Ethernet is needed and the exact n configuration is verified, or choose a documented mono MFP if copying, scanning, fax, or automatic duplex is part of the routine.
Before you buy
Does the B2400 43641801 include Ethernet?
No. OKI separates the Ethernet-equipped B2400n from the base B2400 with USB and parallel.
Is this model a laser printer?
OKI identifies it as an LED printer. The category includes the office-print role while the review preserves that technology distinction.
Does OKI document automatic duplex for the B2400?
The reviewed U.S. sheet does not establish either automatic or manual duplex support for part 43641801.
What monthly volume does OKI recommend?
No recommended monthly range is established in the reviewed B2400 materials; the 15,000-page figure is a maximum duty cycle.
Can it copy or scan?
No. OKI describes the B2400 as a monochrome print-only model without copier or scanner functions.

The decision
The B2400 is a mono LED printer for a direct USB or parallel setup. Its exact part, absence of established networking, unknown duplex support, and missing monthly recommendation should guide the comparison.
