First, have you restarted your computer with the scanner turned on? If not, I suggest you do that. Most computers have to "find" the scanner during the initial system startup.
Second, if after a system startup (with the scanner turned on) you still are not able to scan, open your Systems Propteries window/Device Manager and look for the "Imaging Device" entry.
Open Systems Propterties
1. Right click on "My computer"
2. Choose "Properties"
3. Click Device Manager
4. Look for the entry "Imaging Device"
5. Click the + sign to the left of the Imaging Device entry
6. This should show you your scanner. If it does not, you will need to uninstall/reinstall the the HP Office Jet K60 software.
You can uninstall the software using the installation CD (in most cases). Just put the CD into the drive, then use the "uninstall" link.
Once the uninstall is complete, shut your computer off and follow the directions to reinstall the HP Office Jet K60.
Pay particular attention to when the printer should be connected to the computer. Usually a parallel connection is done before starting your computer and a USB connection connected only when prompted by the software. Sometimes the software will need to be installed, then the computer shut down and the printer connected.
