Question details
The user is unable to adjust scanner resolution settings due to conflicts between TWAIN and WIA drivers in Acrobat Pro XI.
- Product
- Adobe Acrobat Pro XI
- Device & OS
- not provided
- Scenario
- Attempting to scan a physical document into a PDF with specific resolution presets.
- Observed behavior
- The TWAIN option shows presets but fails to connect to the scanner, whereas the WIA option successfully connects but disables scanner presets and resolution configurations.
Ensure your scanner is securely connected to your computer and powered on. It is highly recommended to visit your scanner manufacturer's website to verify that you have the most up-to-date drivers installed.
Use the Scanner's Native Interface
Bypass Acrobat's default scanning dialog to utilize the manufacturer's built-in software, which grants full control over resolution and presets.
Acrobat Pro XI sometimes struggles to bridge the communication gap with third-party TWAIN and WIA drivers. Using the scanner's native interface forces Acrobat to hand over the configuration process directly to your device's original software.
Launch Adobe Acrobat Pro XI and initiate a scan. Click on the 'Options' button located next to your listed scanner.
In the options menu, select the 'Show Scanner's Native Interface' setting.
Click 'Scan'. This will open your scanner manufacturer's proprietary settings window, allowing you to freely adjust the resolution and color presets before finalizing the scan.
Update or Reinstall Scanner Drivers
Resolve underlying connection errors by ensuring your scanner's TWAIN drivers are up-to-date and compatible with your system.
Scan Documents to PDF Seamlessly with WPS Office
If legacy software like Acrobat Pro XI continues to have driver conflicts, upgrade your workflow with WPS Office. WPS provides native integration with modern scanners, allowing you to easily digitize documents to high-quality PDFs without driver connectivity issues.
- 1. Launch WPS PDF: Open WPS Office and navigate to the 'PDF' tab on the main interface.
- 2. Select the Scan Tool: Click on 'Picture to PDF' or the dedicated 'Scan' tool from the top toolbar.
- 3. Configure and Scan: Select your connected scanner, adjust your desired resolution settings natively, and click 'Scan' to generate your PDF instantly.
Frequently Asked Questions
Why does my scanner appear twice in the Acrobat device list?
Your scanner appears twice because your operating system installed both a TWAIN driver and a WIA (Windows Image Acquisition) driver for the same device. Each driver uses a different protocol to communicate with your scanner.
What is the difference between TWAIN and WIA scanner options?
TWAIN is an industry standard that allows software to access a scanner's advanced and specific settings (like custom resolution presets). WIA is a Microsoft standard that provides basic scanning functionality but frequently limits access to the scanner's advanced configuration features.
Why can't I change the scan resolution when using WIA?
WIA drivers often default to basic, standardized settings to ensure broad compatibility across different Windows applications. To change advanced settings like resolution, you must switch to the TWAIN driver or use the scanner's native interface.
Is Adobe Acrobat Pro XI still supported for scanner driver updates?
No, Adobe Acrobat Pro XI is a legacy application and reached the end of its support lifecycle in 2017. It no longer receives updates to ensure compatibility with modern TWAIN or WIA drivers, which is why native scanner interfaces or modern alternatives are recommended.
