Question details
The user needs to configure a scanner in Adobe Acrobat but the Scanner Device list appears blank.
- Product
- Adobe Acrobat
- Device & OS
- not provided
- Scenario
- Attempting to create a PDF from a scanner using the File menu.
- Observed behavior
- The Scanner Device list is blank under File > Create > PDF from Scanner, indicating Acrobat is not detecting the connected scanner or printer.
Ensure your scanner or multifunction printer is properly connected to your computer, powered on, and recognized by your operating system's default scanning utility.
Update Scanner Drivers and Verify Connection
Installing the latest TWAIN or WIA drivers ensures Acrobat can communicate with your scanning hardware.
Acrobat relies on specific driver protocols to interface with external hardware. If these drivers are outdated, missing, or incompatible with your current operating system, the device list will remain blank.
Open your operating system's built-in scanning utility (such as Windows Fax and Scan or macOS Image Capture) to confirm the scanner works outside of Acrobat.
Visit the scanner manufacturer's official website to download and install the latest TWAIN or WIA drivers for your specific device model and operating system.
Close Adobe Acrobat completely and reopen the application to force it to refresh the connected device list.
Navigate to File > Create > PDF from Scanner and check if your device now appears in the Scanner Device dropdown menu.
