Solution 1Recommended

Close Open Documents Before Scanning

The most straightforward way to prevent Acrobat from appending scanned pages to an existing document is to ensure no PDFs are open in the background.

Acrobat's scanning workflow often defaults to appending new scans to the active document to speed up multi-page compilation. By removing the active document, you force Acrobat to start fresh.

1
Close active files

Click 'File' in the top menu bar and select 'Close' for any PDF documents that are currently open.

2
Initiate a new scan

Go to 'File' > 'Create' > 'PDF from Scanner' to start your scanning process.

3
Save the new document

Once the scan completes, Acrobat will open the scanned pages as a brand new, separate PDF. Go to 'File' > 'Save As' to name and store your new file.

Quick Fix: This method overrides any hidden default settings by simply removing the target document Acrobat is trying to append to.

Frequently Asked Questions

Why does Acrobat automatically append my scanned pages to an open PDF?

In some versions like Acrobat 2017, the default scanning workflow appends new scans to the active document to speed up multi-page document creation. Closing the open document before scanning resolves this.

Can I permanently change the default scan behavior in Acrobat 2017?

Acrobat 2017 may not expose a persistent default setting to stop appending. You often need to manually select 'Create New PDF' in the scanner output options under Tools > Create PDF each time, or simply close open PDFs.

How do I extract pages if I accidentally appended them to the wrong PDF?

Open the PDF with the mistakenly appended pages. Go to Tools > Organize Pages, select the newly appended pages, and click 'Extract' to save them as a separate file. You can then delete those pages from the current document.
