HP OFFICEJET J5780 HOW TO GET SCANNER TO WORK

Kindly install the scanner software for printer the driver software cd just re install it will install the scanner software and make sure in device manger there is not other usb device listed if it is there just remove it. And refresh it in will automatically install the driver.

I had this problem too, and after a while just gave up on the uesless HP interface, and went to the simple but efficient Windows Fax and Scan program on the Start>Programs menu.

If you do not have the software, you need to download the software fromthe following location:

HP Officejet J5780 All-in-One Printer

Chose 'software and drivers' link on page above.
Chose operative system and follow instructions to download the printer driver.
After downloading is finished, unplug the printer USB and run the software that you downloaded.
The software installer will tell you when to connect USB.

go into tool on pc and open paint, that,s what works for me. or call hp and they will walk you thur

it means that te software for the scanner is not properly installed or corrupted,reinstalling the software will solve
