- Device & OS
- not provided
- Scenario
- Scanning physical documents into a digital PDF format and noticing inconsistent page orientations.
- Observed behavior
- The resulting scanned PDF contains pages with mixed orientations, despite the original physical documents being placed in the feeder in the same direction.
Verify that your physical documents are neatly stacked and correctly aligned in the scanner's automatic document feeder before attempting a new scan.
Rotate Incorrect Pages in Your PDF Editor
The quickest way to fix an existing document with a few incorrectly oriented pages is to use the page organization tools in your PDF editor.
If you have already scanned the document and do not want to rescan it, modern PDF editors allow you to manually rotate individual or multiple pages to correct their orientation.
Launch your PDF editing software (such as WPS Office or Adobe Acrobat) and open the scanned PDF file.
Navigate to the 'Page' or 'Organize Pages' tab in the top menu to view thumbnails of all the pages in your document.
Select the specific pages that are upside down or sideways. Click the 'Rotate Clockwise' or 'Rotate Counterclockwise' button until the pages are upright.
Go to 'File' and select 'Save' to permanently apply the rotation to your PDF document.
Adjust Scanner Settings and Re-scan
Modify your scanner's duplex and automatic rotation settings to ensure all pages are scanned in the correct orientation from the start.
Update Scanner Drivers and Software
Outdated scanner drivers or firmware can cause unpredictable document feeding and page orientation issues.

Frequently Asked Questions
Why are the back pages of my two-sided scan upside down?
This typically happens due to incorrect duplex scanning settings. Check your scanner's settings to ensure it is configured for 'long-edge binding' (standard for portrait documents) rather than 'short-edge binding'.
Can I rotate all pages in a PDF at once?
Yes. In most PDF editors, including WPS Office, you can select all pages in the Page Organize view by pressing Ctrl+A (or Cmd+A on Mac) and apply a rotation to the entire document simultaneously.
What is the automatic rotation feature in scanning?
Automatic rotation is a feature in scanner software that detects text orientation and automatically rotates the digital image to make the text upright. However, if it misinterprets a page, especially one with images or non-standard layouts, it might rotate it incorrectly.
