Scan an image
You can start a scan from your computer or from the HP All-in-One. This section
explains how to scan from the control panel of the HP All-in-One only.
To use the scan features, the HP All-in-One and computer must be connected and
turned on. The HP Photosmart Software (Windows) or HP Photosmart Mac Software
(Mac) must also be installed and running on your computer prior to scanning.
● On a Windows computer, look for the HP Digital Imaging Monitor icon in the
Windows system tray (at the lower right side of the screen, near the time) to verify
the software is running.
HP All-in-One overview
Note Closing the HP Digital Imaging Monitor icon in the Windows
system tray can cause the HP All-in-One to lose some of its scan
functionality. If this happens, you can restore full functionality by restarting
your computer or by starting the HP Photosmart Software.
● On a Mac, the software is always running.
Tip You can use the HP Photosmart Software (Windows) or HP Photosmart
Mac Software (Mac) to scan images, including panorama images. Using this
software, you can also edit, print, and even share your scanned images. For
more information, see the onscreen Help that came with the HP All-in-One.
