How the printer is connected to PC Via USB or using Network Cable. If it is connected Netwrok cable than printer configuration page and on netwrok configuration there will be IP Address if this is valid IP Address than reinstall drivers and upgrade the Firmware of the printer.

If Printer is connected USB than try different USB Cable and try different USB Port on the computer
If USB port on the computer is working fine and check in Device Manager if the printer has detected as unknown device or not detected at all.
If detected as unknown device than reinstall printer driver if not detected at all than USB Port on the printer is faulty you need to set up hardware repair of the printer.

I fixed this by completely uninstalling the Lexmark software, then unplugging the USB and restarting. I then installed the new Lexmark software that I downloaded from their site, make sure not to plug the USB back in until it told me to. It then detected the printer properly and started working.

Although Lexmark has not released a Windows Vista driver for the Lexmark X75 printer, there is a good chance that Vista will support your printer without the need for installing a driver (i.e. Windows Vista probably comes with a driver for your printer already built into the operating system). Windows Vista comes with support for 2.2 million devices and since your printer is not a new model, it is likely to be supported. Just try connecting it to a computer that is running Windows Vista and see if it is detected and installed for you.

We do have the drivers for Windows 2000 and Windows XP available for download from our driver database:
