How to Continue and Reorder an Interrupted Duplex Scan in Acrobat
Question details
The user wants to resume an interrupted scanning session and automatically interleave the back pages with the front pages in Adobe Acrobat.

- Product
- Adobe Acrobat
- Device & OS
- not provided
- Scenario
- Scanning the front and back sides of physical documents using a non-duplex scanner via Adobe Acrobat.
- Observed behavior
- When the scan is interrupted, the software loses the prompt to scan the back sides, and the automatic page reordering and interleaving functionality is no longer available.
Save any pages that were successfully scanned prior to the interruption to prevent data loss, and verify that your scanner's USB connection is secure.
Manually Combine and Reorder the Scanned Pages
Since Acrobat cannot automatically resume the interleaved scan after a crash, you must scan the remaining pages separately and organize them manually.
Acrobat's automatic front-to-back interleaving workflow resets completely upon interruption. To complete your document without starting over from scratch, you need to treat the remaining front and back pages as independent scans and manually merge them into the correct order.
Save the PDF file containing the pages that were successfully scanned before the interruption occurred.
Start a new scanning session for the remaining front pages and save them as a separate PDF. Do the same for the corresponding back pages.
Open Acrobat, navigate to 'Tools' > 'Combine Files', and add your initial scan, the new fronts, and the new backs into a single combined document.
Open the 'Organize Pages' tool in Acrobat. Drag the back pages into their correct positions, interleaving them between the front pages to recreate the proper duplex order.

Update Software to Prevent Future Interruptions
Frequent scan interruptions are often caused by outdated scanner drivers, loose cables, or software bugs within Acrobat.
Combine and Reorder Scanned Pages Easily with WPS Office
If your scan was interrupted, you can easily merge your separate front and back PDF files using WPS Office. Its intuitive page management tools allow you to seamlessly drag, drop, and reorganize pages into the correct duplex order.
- 1. Open WPS Office: Launch WPS Office and open the PDF containing your initial scanned pages.
- 2. Merge New Scans: Go to the 'Page' tab and select 'Insert Pages' or use the 'Merge PDF' tool to add your newly scanned front and back pages to the document.
- 3. Organize Pages: Click on 'Page Management' to view all pages as thumbnails. Simply drag and drop the back pages to interleave them correctly with the front pages.
- 4. Save the Document: Once the pages are in the correct duplex order, click the Save icon or press Ctrl+S to finalize your complete PDF document.

Frequently Asked Questions
Can I force Adobe Acrobat to resume an interrupted scan?
No, Acrobat does not have a preference setting or recovery feature to resume an interrupted front-and-back scan workflow while preserving automatic page interleaving. The session resets upon interruption.
Why does my scanner keep stopping in the middle of a scan?
Scan interruptions can be caused by loose USB connections, outdated scanner drivers, hardware conflicts, or software bugs. Ensuring your cables are secure and updating both your scanner driver and PDF software can help resolve this.
Is there scanner software that allows resuming an interrupted scan?
Some proprietary scanner software provided directly by the manufacturer supports resumable duplex-style scanning better than third-party applications like Acrobat. Check the software bundled with your specific scanner for advanced recovery options.
How do I interleave front and back pages manually in a PDF?
To interleave pages manually, you can use the 'Organize Pages' feature in Adobe Acrobat or the 'Page Management' tab in WPS Office. You will need to view the page thumbnails and physically drag the back pages to place them between the respective front pages.
