Our take
The OKI C712dn is a color LED print-only workgroup model. OKI's product page rates the C712 series up to 34 pages per minute in color and 36 ppm in monochrome on A4, and lists a 530-sheet tray plus a 100-sheet multipurpose feed, Gigabit Ethernet, optional Wi-Fi and a recommended monthly volume of 6,000 pages. OKI states the product was discontinued in March 2022. Automatic duplex should remain unconfirmed for the exact offered configuration: the C712dn suffix suggests a variant, but OKI's accessories page lists a duplex unit among options and the checked sources do not resolve whether it is standard on this candidate. This is a worthwhile wired color option only when the buyer verifies the label, duplex hardware and local support situation. The Amazon search does not establish present availability or included accessories.
A wired workgroup needing color LED output and a large input supply, with configuration and duplex verified before purchase..
Skip it if automatic duplex must be guaranteed without inspection, if built-in Wi-Fi is required, or if current manufacturer availability is essential.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- OKI lists 34 ppm color and 36 ppm monochrome on A4.
- A 530-sheet tray plus a 100-sheet multipurpose feed provide substantial listed paper input.

What to weigh up
- OKI marks the C712 series discontinued as of March 2022.
- The checked sources do not settle whether automatic duplex is standard on this exact configuration.
- Wireless is optional, and the series specification uses A4 speed figures.

Full review: how the features affect your choice
What the features mean for you
A dedicated color LED print engine
OKI identifies the C712 as a color LED printer for document output, not an all-in-one with integrated scanning or fax. The C712dn is therefore a better comparison for a shared color queue than for a household seeking every paper task in one machine. The product series is discontinued, which changes the practical evaluation: check local service options, compatible supplies and drivers before depending on it. Confirm the model label on the actual printer because the source page covers the C712 series and related configurations. The official product information is the starting point for the specification ([OKI C712 series](https://www.oki.com/eu/printing/products/colour/discontinued/c712/index.html)).
A4 speed and input are documented
OKI rates the series at up to 34 pages per minute in color and 36 in monochrome on A4. Those rates help compare the model with other A4-rated office printers, but should not be silently restated as Letter speeds. The listed paper supply is a 530-sheet tray plus a 100-sheet multipurpose feed. That is substantial input for a shared device and can reduce reload interruptions, provided both parts are present and working on the offered machine. Check the feeds, size guides and supported media in the manual before planning a specific stock workflow.
Duplex is the key configuration question
The model name ends in dn, but the checked OKI accessories information lists a duplex unit as an option for the C712 series. The available manufacturer evidence does not settle whether the exact C712dn candidate has the unit as standard or whether the word dn identifies the configuration represented in this listing. The profile therefore leaves automatic and manual duplex unknown rather than assuming. A buyer who requires two-sided output should verify the exact hardware or an exact manual before purchase and test a duplex job on the offered device. This distinction matters more than a suffix-based guess.
Wired networking is standard in the reviewed source
OKI lists Gigabit Ethernet and USB for the C712 series. Wireless is an optional capability, not a confirmed built-in interface for the standard configuration. A shared office can use the documented wired network path if the port and driver are supported; a wireless-only location should verify an installed option rather than rely on a broad model description. Since the family is discontinued, check driver access and local network compatibility before placing it into a long-term role. The physical label and installed interfaces on the exact printer remain important evidence.
The monthly recommendation is a point, not a range
OKI states a recommended monthly page volume of 6,000 and a separate maximum duty cycle of 100,000 pages. The 6,000-page figure is a monthly recommendation, while the duty cycle is a maximum; they should not be confused. The checked material gives a single recommendation rather than a lower-and-upper range, so the matching profile keeps the range endpoints unknown and preserves the single value in the article. If a finder requires a true operating band, seek more detailed exact-model guidance rather than turning one point into invented boundaries.
Compare for your needs
For confirmed standard automatic duplex choose a model whose exact configuration source states it; for current support compare an in-production color LED or laser printer.
