Oki B431DN print server


Design Like most monochrome printers, don't expect to see the B431DN strutting down the catwalk--its matte black design is meant to match the universally drab aesthetic of most office electronics, but what it lacks in elegance, it makes up for in...

Impressive output speed and print quality; networking with Ethernet port; duplexer for double-sided printing; extra-large 350-sheet paper input tray.

Lacks desktop companion software; no USB cable included.

The Oki B431DN is truly a workhorse black-and-white laser printer, with rapid output speed and high print quality. Combined with extra features like an autoduplexer and a large paper input capacity, the Oki B431DN is worth your dollar.

OKI B431dn


The printer also offers better than usual paper handling, with a built-in duplexer to print on both sides of a page and a 350-sheet input capacity divided into a 250-sheet tray and a 100-sheet multipurpose tray. The second tray lets you keep a second...

Fast. Built-in duplexer and 350-sheet capacity standard, with 830-sheet maximum. Ethernet connection. Relatively small

Although text is easily good enough for most business uses, it's a touch sub-par because of an issue with small fonts

The OKI B431dn's combination of fast speed, paper handling, and small size make it a highly attractive choice for a small office or workgroup.

OKI B431dn


An excellent, mid-range LED printer, with good speed and print quality. Hard to read its display, though.

"Good printers while they work."


I have about 30 Brother printers and we decided to look at our next default printer as Brother discontinued the model we use. One of the IT guys did a cost analysis of the Oki B431 and all looked well. The problem, he didn't factor in bad reliability...

10K Toners, Speed comparable to similar model, Easy for users to replace toner

Expensive Drum to Replace, Toner not widely sold, Toner cost isn't better then other machines.

"Works well but supplies are expensive"


I searched for hours to find a way to reset the drum counter on the B431 but it still remains a secret. Other Okidata printers have been solved but not the B431. All printer manufacturers are trying to lock the customer into buying their overpriced...

Prints fast and pages are crisp and neat

Toner is very expensive and so are drums. It will tell you to replace the drum before it is worn out (still printing perfectly) and will not print any more until you do so.

Great printer for what I needed


I work in finance, and my job requires printing fairly long text-based documents such as annual reports, quarterly reports, etc. Therefore I had a very specific need - a workhorse printer that can churn out double-sided pages of (mostly) text. I wasn't...

I hear the toner cartridge refills are expensive, but that's probably true for most printers

Great Printer


Great printer, one of the best I have ever owned. I replaced two Brother HL-5240 printers with this one. The Brothers were very nice printers, but this Oki is nicer made. I plan to buy one more as a back up in the next few weeks

It was a bit stinky when it printed the first hundred pages. It give you a blast of a chemical smell as the paper feeds out. I asked the Oki tech about this while calling in to figure out how the front paper feed works. They said it has a very hot...

Great little printer


We are switching our entire office over to OKI printers because the toner cost is so much lower than HP or Brother. In the end it will only take 3 months for 5 printers to pay for themselves.

All OKI printers seem to sip toner, I actually get more pages than they list. The overall toner cost is about 40% less than the HP it replaces ; Print cost is awesome ; Print quality is spectacular

The driver had to be installed manually on Windows 7x64 for some reason

This really is a nice printer, I got it when it was on sale for $249 so it was an even better deal. But even at the current price it is still a good buy. I would recommend this printer for a home or business use. We use it for home use, (two daughters...

We were using a HP Laserjet 4 Plus but it was getting pretty old and was starting to have problems so we went with a new printer rather than repairing the old one ; Fairly easy to set up on a home network. Prints very fast and the text is sharp and crisp

I am not crazy about the color but that's not really a con, just a personal preference
