Default administrator login username and password for an Oki B430dn printer?
Posted by rbTech Staff, Last modified by rbTech Staff on 07 March 2013 04:16 PM
This is really too silly of a topic to even put up a post about except for one thing: This information literally doesn't exist anywhere else on the Internet.

So, if you're the proud owner of a new Okidata B430dn (which, by all accounts, is quite a nice little printer), and you're trying to log in to the Administrator interface via the embedded webserver, you need the following info:

Username: admin

The default password is set to the last 6 digits of the MAC address of your printer (which is printed on a sticker on the back of the device near the network port). Be aware, this string is CASE SENSITIVE! e.g.: 0011AC

I hope this saves someone the hour plus of digging that it took me to find it :)

yes it did! thanks a lot. Now... if I could only figure out how to get it working properly as a network printer? Works fine with Windows 7, but struggling with XP & mac OS...

The simplest way to print to it as a network printer is to set up a standard TCP/IP port in Windows, and then install the driver as per normal. E.g.: New printer wizard, add a port, standard TCP/IP port, specify the IP address of the printer in the port setup, then specify the path to the driver when prompted. There's some silly program that comes on the CD that will attempt to find the printer on your LAN by MAC address but it doesn't always work in my experience.

And the same for my MC352. I cannot believe that this is nowhere in the setup and configuration manuals. Not terribly impressed with the setup guides so far :-(

And @Rubin, I think you may be missing the point. By default the printer will obtain an IP address via DHCP. That's fine, you can hook it up and all work happily, until for some reaon the printer is powered off and an restart gets a different IP. At that point every machine you have setup to print to it will fail as the printer's IP has changed, hence you have to set a static IP for the printer and for that you need the little confir utility on the CD and to make the change you need the admin password...which is the crucial piece of info you provide thank for 'sharing' what Oki ought to make plain. Just how though did you come across this gem?

Please does somebody know how to swith to typing in capitals when entering the admin password / mac address? I can't find it anywhere in the manual nor online.

Hi, Iain
We generally do set the IP address statically, though sometimes we'll set a static lease in the DHCP server depending on the specifics of the network we're working on. In either case, you're right - the printer definitely needs to consistently be assigned the same IP address or you'll be in for some frustration when the DHCP server assigns a new IP to the device and you can't print to it anymore.

And where I came across this gem was (I think) in either the crummy owner's manual that I have squirreled away in a filing cabinet, or on the equally crummy Oki website. It's a really obscure reference somewhere in a setup article, and (obviously, if the amount of traffic to this page is any indicator) poorly indexed.

@Mqruis, The later model MFCs like yours have a different password scheme, likely because Okidata got a lot of negative feedback about the silly password they set on this generation of monochrome printers. We recently upgraded to an MC562 here and it also has the admin/aaaaaa password by default.
02 November 2013 12:14 PM
Hi, thank you for the information. I put all numbers which I found on stickers but nothing worked. Password "aaaaaa" was the only right. It's ridiculous and embarassing that OKI doesn't put this anywhere. People must be lost and dissapointed. :-(

Print to the Hostname of the device and not the IP address. Then you don't have to worry about the IP address changing. You can only do it this way if you are connected to a DNS server. To test type the hostname into any address bar browser.

@Dave, your are correct, it's most certainly best practice to use the hostname not the IP address. However lots of (very) small networks do not have proper internal DNS and/ or WINS hostname resolution, so printing by IP may be a better option for some. We typically set printers up with a static address (or a static lease at minimum) and forward and reverse DNS records, and so are able to create a port by hostname rather than IP. Thanks for your comment!

...And, for all the other printers out there...

Wish they had a permalink to this information but as of 2014.05.14 this link worked.

I don't suppose you've cracked updating the formware on an Oki have you?

My MC352dn is supposed to be AirPrint ready but the I can see the AirPrint menu is missing and the CU version is 02.37 AirPrint came with CU 02.70 so no wonder there's no AirPrint.

There is an update util and a firmware bin, but the update util can't find the printer although I can' ping it, print to it and even access the web admin console. There also seem to be no means to tell the printer to directly upload the bin file so I can't push it to the printer and there seem no means to have it pull it :-(

I also discovered my admin password is now 'aaaaaa' and not the last three hex values of the MAC (in upper case). Not sure how that changed!

After several calls to a highly professional OKI support premium 'Hotline' in France (+33 1 76 54 21 50) totalling over an hour, they finally told me they'd get a technician to call me... I'm still waiting....
Next, I called the OKI hotline in the UK, (+44 1784 274318) Very helpful, albeit late on Friday afternoon isn't the best time to call(!)
I'll shortly be calling the Hotline in the US (+1 800 654 3282)....
Bottom line it seems that there are 2 use names: "admin" and "root"
and there are 2 passwords: "aaaaaa" and also the last 6 figues of your "MAC" number. You'll have to try both with each to see what works for you.
For me, none of this worked (MC562)... I was sent a link to download a utility called "LPR UTILITY" which is for resetting the password to the supposed factory default of "aaaaaa"... that's the good news IF you're running Windows... The bad news for Mac users is that the utility doesn't work on Mac(!)... so find a PC friend with a laptop!
I have to confess that wasting this much time is enough to stop me buying another OKI product
