After having bought a pc with Windows 8, I installed software and drivers for My Printer version 3.1.0 with mypr-win-3_1_0-ea11_2.exe.
The printing works well, but the scanning function does not work. Does anyone recognize this issue or knows how I can resolve this?

In order to assist you better on the issue, I would need more information on the issue:

1. What is the make and model of the computer and printer?
2. Have you made any changes to the computer prior to the issue?
3. Did you try the printer on a different computer to check if it’s an issue with the computer or printer?

This issue could occur if there is a compatibility issue between the printer and the computer. Please follow the methods to resolve the issue.

Method 1: Use a troubleshooter to fix the issue:
a. Type "Troubleshooting" on the start Screen and hit enter
c. Click on “Hardware and Sound”
d. Select Hardware and devices,
e. Run the troubleshooter and restart the computer.

Method 2: Uninstall from Device Manager.
a. Type Device manager on the start page and hit “Settings”
b. Find Printers and expand it. Right click on the driver select Uninstall.
c. Restart the computer. Go to the manufacturer’s website and install the driver.
