How to Fix Acrobat XI Cannot Recognize Scanner on Windows
Question details
The user needs to resolve an issue where Acrobat XI lists a connected scanner but fails to communicate with it, preventing document scanning.
- Product
- Adobe Acrobat XI
- Device & OS
- Windows
- Scenario
- Attempting to scan physical documents directly into a PDF file using Acrobat XI.
- Observed behavior
- Acrobat displays errors like 'Cannot communicate with the scanner' or 'the selected scanner was not found', even though the scanner functions normally in other Windows applications.
Ensure that your scanner is powered on, securely connected to your computer via USB or network, and works properly in the default Windows Fax and Scan application.
Enable the Scanner's Native Interface in Acrobat
Switching from Acrobat's hidden interface to the scanner's native interface often resolves communication errors and driver conflicts.
By default, Acrobat tries to hide the manufacturer's scanning software interface to streamline the process. However, this can cause communication failures with certain Canon, Brother, and other scanners. Forcing Acrobat to show the native interface usually bypasses this bug.
Launch Adobe Acrobat XI. Go to File > Create > PDF from Scanner, and select 'Custom Scan' from the menu.
In the Custom Scan dialog box, locate the 'User Interface' dropdown menu under the Scanner section. Change the setting from 'Hide Scanner's Native Interface' to 'Show Scanner's Native Interface'.
Click the 'Scan' button. Your scanner's proprietary software window should now pop up, allowing you to scan the document successfully.
Update Scanner Drivers and Check Windows Profiles
Use this method if changing the interface settings does not restore scanner functionality.
Verify Your Active Internet Connection
Address a known bug where network disruptions can cause Acrobat to lock up during the scanning process.
Scan Documents to PDF Seamlessly with WPS Office
If Acrobat XI continues to experience driver conflicts or interface errors with your scanner, try using WPS Office. Its built-in PDF scanning tool offers excellent hardware compatibility, allowing you to turn physical documents into PDFs without the hassle.
- 1. Open WPS PDF: Launch WPS Office on your Windows computer and navigate to the 'PDF' tab on the home screen.
- 2. Select the Scanner Tool: Click on 'Scanner' or 'Picture to PDF' from the available tools menu.
- 3. Choose Your Device: Select your connected scanner (e.g., Canon, Brother, HP) from the device drop-down list.
- 4. Scan and Save: Configure your preferred resolution and color settings, then click 'Scan' to instantly digitize your document into a high-quality PDF.
Frequently Asked Questions
Why does my scanner work in other Windows applications but not Acrobat XI?
Acrobat XI uses specific TWAIN/WIA driver protocols and defaults to hiding the scanner's native interface. If the scanner's driver requires its own software window to process the scan, Acrobat's hidden mode will cause communication to fail, resulting in an error.
How do I fix the 'selected scanner was not found' error?
First, navigate to File > Create > PDF from Scanner > Custom Scan, and change the User Interface option to 'Show Scanner's Native Interface'. If the error persists, update your scanner drivers via the Windows Device Manager.
Can an unstable internet connection affect PDF scanning in Acrobat?
Yes. Due to Adobe's background account authentication and sync processes, some users experience local hardware lockups or scanner communication errors if their internet connection drops while Acrobat is running.
What should I do if my scanner is missing from Configure Presets?
If the only choice is 'Please Select a Device' and no scanners are listed, completely uninstall your current scanner drivers, reboot your PC, and install the latest drivers from the manufacturer's official website.
