How to Install A scanner?
Installing a scanner on newer PCs is pretty straight-forward. If the scanner is a USB device, you'll need to install the software CD that came with the scanner. These will normally be one or two disks and a few others that usually only prove to be trial software or other programs you do not need. Be wary of installing these third-party CDs, as you likely will never use them and they tend to want to take over the way media is handled on your computer.
First, unpack the scanner from the box. Make sure you have all of the attachments and especially the quick setup instructions if they were in the box. You can assemble the scanner and set if off to the side. You can plug the power cable in, but do not plug the USB cable into the computer.
Boot up the computer and load the scanner software disk into the CD ROM drive. If it does not launch automatically, you can navigate to it through My Computer and click the setup.exe file. If there are additional disks for your scanner that need to be loaded, you will be prompted for them.
Once the software has been installed, you can then attach the USB cable to the computer. Windows should find the new scanner and load the drivers for it automatically.
Troubleshooting Scanner Problems:
If your scanner had worked in the past but has stopped functioning, you can usually unplug the scanner, then go to Add / Remove Programs in the Control Panel and remove the scanning software. Then you can repeat the installation process above.
If the scanner never worked, you may have a problem with the USB port . Check another device to see if it works in that port.
