Hello Lulu !
To use the scan features, the HP All-in-One and computer must be connected and turned
on. The HP Photosmart Software must also be installed and running on your computer
prior to scanning. To verify that the HP Photosmart Software is running on a indowscan
computer, look for the HP Digital Imaging Monitor
icon in the system tray at the lower
right side of the screen, near the time.
To scan to a computer
Load your original print side down on the right front corner of the glass.
A preview image of the scan appears on your computer, where you can edit it. Any
edits that you make apply to the current scan session only.
The HP Photosmart Software has many tools that you can use to edit your scanned
image. You can improve the overall image quality by adjusting the brightness,
sharpness, color tone, or saturation. You can also crop, rotate, or resize the image.
Make any edits to the preview image, and then click Accept
when you are finished.
