How to Install OKI Drivers

Below are instructions for downloading and installing our printer drivers.

The Driver installation methods may vary slightly. The instructions displayed during installation will guide you through a successful installation. A “readme.txt” file is included and describes further instruction on installations of any individual components. Be sure to write down the folder name(s) you saved and/or expanded any files to. Before proceeding with the software installation, the printer and computer must be installed and powered on. Make sure that the printer is connected to the computer (remove any switchboxes or other devices using the same port). Make sure that all cable connections are tight.

To Download Drivers from our website

After locating the software/driver for your product on our website click on the download link. Follow the instructions on your computer screen to save the file to your hard disk. (Write down the location of where you saved the file.)

Windows 2000 / Windows XP

Some Download packages from the website contain automatic installers. Once driver is downloaded click on the downloaded file to begin driver installation. For all other types of driver downloads, double click on the downloaded file and run through the extraction process and then follow the instructions below:

  1. Go to Start, Settings, Control Panel, Printers and Faxes.
  2. Click on Add a Printer.
  3. Proceed until you get to the list of Manufacturers and Printers.
  4. Click on “Have Disk” and then browse to the location where the files where copied. For Example, a C3450 path would look like this “C:\OkiDriver\OkiC3450” The last file you will double click on is the OKB3H030.INF file and then proceed with the installation.
  5. Follow through the rest of the steps and the printer will be installed.

Windows Vista / Windows 7

Some Download packages from the website contain automatic installers. Once driver is downloaded click on the downloaded file to begin driver installation. For all other types of driver downloads, double click on the downloaded file and run through the extraction process and then follow the instructions below:

  1. Click on the “Windows” button on the bottom left of the screen. (Used to be the Start Button)
  2. Go to Control Panel, Hardware and Sound, Printers (in Windows 7 it is called Devices and Printers), Add a Printer.
  3. Proceed until you get to the list of Manufacturers and Printers.
  4. Click on “Have Disk” and then browse to the location where the files where copied. For Example, a C3450 path would look like this:”C:\OkiDriver\OkiC3450” The last file you double click on will be the OKB3H030.INF file and then proceed with the installation.
  5. Follow through the rest of the steps and the printer will be added.

Windows 8

Some Download packages from the website contain automatic installers. Once driver is downloaded click on the downloaded file to begin driver installation. For all other types of driver downloads, double click on the downloaded file and run through the extraction process and then follow the instructions below:

  1. From the initial start screen right click on a blank area. On the bottom right you will see an option for “all apps”. Click on that.
  2. Click on Control Panel, Hardware and Sound, Devices and Printers, Add a Printer.
  3. The next screen that comes up will show windows searching for your printer. The best thing to do in most cases is to click “stop”. Then click next and you will come to the manufacturers and printers screen. Click on Have Disk and browse for the files just like in the Windows 7 / Vista install. ( In some cases we may not have a driver available for your specific printer so it would be wise to allow windows to detect the printer and automatically install a generic PCL driver). This is on a case by case basis.

If you get a message during the driver install that tells you the specified driver cannot be installed as it’s not digitally signed then you won’t be able to complete the installation process. Follow the instructions below to bypass this and add the printer anyway:

  1. Go to the initial start screen.
  2. Move your mouse to the upper right hand corner to invoke a right side menu to pop out.
  3. Click on settings.
  4. Click on Power.
  5. Hold down the shift button on your keyboard while clicking restart.
  6. Go to Troubleshoot, Advanced Options, Startup Settings and then click restart.
  7. Push 7 on your keyboard (disable driver signature enforcement).
  8. The printer will now reboot and you will be able to follow the steps above and add the printer.
  9. The next time you restart your PC your startup settings will go back to default. If you ever need to add another printer of this type then you will need to repeat these steps.
