8 HP PhotoSmart S20 Photo Scanner Basics
Quick Setup
Connecting Your Photo Scanner
When the HP PhotoSmart Setup Wizard prompts you to do so, connect your
photo scanner to a power outlet and to your PC, as follows:
1. Connect the small end plug of the power cable to the power connector
on the back of your photo scanner. (The power connector is to the left
of the USB connector on the back of the photo scanner.)
2. Plug the other end of the power cable into a power outlet.
3. Locate the USB connector (or port) on the front or back exterior of your
PC. The USB connector looks like this, and should have the distinctive
USB symbol printed by it (usually above the connector), as shown here:
