- Product
- Adobe Acrobat, Fujitsu fi-7160 Scanner
- Device & OS
- not provided
- Scenario
- Creating a PDF directly from a Fujitsu fi-7160 scanner within Adobe Acrobat.
- Observed behavior
- The page-dimension fields in the scanner settings dialog are disabled or grayed out, preventing the user from specifying the correct paper size.
Ensure your Fujitsu fi-7160 scanner is fully connected, turned on, and that you have the latest TWAIN or ISIS drivers installed from the official Fujitsu website.
Select a Custom Paper Size and Update Acrobat
Bypass the locked dimension fields by adjusting the custom size settings and ensuring your Acrobat software is fully up to date.
In many cases, the standard page sizes are locked due to communication glitches between the scanner driver and Adobe Acrobat. Applying an update often resolves these underlying compatibility issues.
In the Acrobat scan dialog, check if the application allows you to select 'Custom Size' in the paper size dropdown instead of standard sizes.
Open Adobe Acrobat, click on 'Help' in the top menu, and select 'Check for Updates'. Install any available updates and restart the application.
Scan a completely different physical document to determine if the error is isolated to the specific dimensions of the previous file.

Use the Acrobat Cleaner Tool to completely remove corrupted installation files that might be interfering with your scanner settings.

Frequently Asked Questions
Why are my scan settings grayed out in Adobe Acrobat?
This usually happens when there is a communication issue between Acrobat and your scanner's TWAIN/WIA driver. It can also occur if the driver dictates the page size natively, overriding Acrobat's controls.
How do I change the default scan size for the Fujitsu fi-7160?
You can change default scan sizes directly within the scanner's driver software (PaperStream Capture). Open your Windows Control Panel, go to Devices and Printers, right-click the scanner, and adjust the default preferences.
Can I use a WIA driver instead of TWAIN to fix this?
Yes. When selecting your scanner in Acrobat, choosing the WIA driver version (if available) instead of the TWAIN driver can sometimes unlock disabled page settings.
Where can I find the Adobe Acrobat Cleaner Tool?
The Adobe Acrobat Cleaner Tool is available for free on Adobe's official support website under enterprise deployment and troubleshooting resources.
