My series 3400 all in one is not communicating with computer. I installed and re-install driver quite a few times with same result, check mark is beside icon in control panel, I unpluged pwr cord and usb cable same result, the printer is fairly new and was working fine up to the time I uninstalled it from another computer.The computer I'm trying to get going is a new Acer notebook aspire mod. 5735z. Printer lexmk x3430. thanks

click start control panel administrative tools computer management device manager scroll to ports(COM&LPT) + to expand you should see a communication port and Ecp printer port

you might see a yellow question / exclamation ? ! mark or a red X this will mean you need to install a new driver for this device right click to update driver

hope this helps

Yes, the installation cd has the All-in-One Center software. But, if you have already used that to install the software, I suggest you download the updated driver from the Lexmark website. Here's the link: http://bit.ly/c9GW5Y. Choose the correct driver compatible with your computer's operating system. Download and install the software. Hope this helps. If you need more assistance, leave a comment and I'll get back to it. Thanks.

Here is the driver software that you need to install to use this printer;

Good Luck!

If you are running Windows XP or Vista, you may use the generic driver for Lexmark 3400 series. All you have to do is to connect the printer to the computer and let the computer detect it. If the printer is not a Plug-n-Play device, the computer would allow you to manually select the generic driver.

Or, you may check any of the links below and download the driver for your Lexmark X3400 for free:

Have a great day!

I cannot get my lexmark 3400 series to install. I already have a 1100 series install on my computer please help

im looking for the software to run 3400 can you help me get it

printer screen shows cover open but it is,none buttons will work

Looking around with Google it could be how your ports are set.i.e USB or Lpt

Download Epson Vista print driver from web, delete old install/ print drivers, install new software driver package.

I had this same problem...drove me crazy for a week. Called the geek squad at Best Buy and they mentioned something about a"patch" (which I had no idea what that meant) on the website of the printer. I went to Lexmark website, and selected 1200 series and windows vista (which is what's installed on my computer) A page came up to install a driver that made the two compatible and it worked!!!
