When scanning batches of paper surveys, your documents often include pages that should not be processed, such as blank backs, cover sheets, or instruction pages. PaperSurvey provides both automatic blank-page detection and a manual IGNORE marker system so you can keep your scanning workflow efficient without generating unnecessary errors.
Automatic blank page detection
The system automatically removes truly blank pages during processing. However, pages with any marks or notes will be flagged for review to ensure no data is accidentally lost.
Pages are kept (rather than discarded) when they contain:
- Handwritten notes or marks
- Stray pen marks or scribbles
- Coffee stains or shadows
- Poor scan quality creating artifacts
Including instruction or cover pages
Many surveys include additional pages such as cover sheets with study information, instruction pages for participants, consent forms, or reference materials. You can include these pages in your scans without triggering processing errors by using the IGNORE marker system.
How to mark pages to ignore
Method 1: Add the IGNORE QR code manually
Add this QR code to any page you want to exclude from processing:
Placement options:
- Bottom-right corner (recommended)
- Top-left corner
When the system detects this QR code, the page is automatically skipped without generating errors.
Example with IGNORE code
Method 2: Upload cover pages in settings
For consistent cover pages across all surveys:
- Go to Survey Settings
- Click "Upload Cover Page"
- Select your PDF file
- The system automatically adds the IGNORE code
This approach ensures consistent formatting across all copies, places the IGNORE code automatically, excludes cover pages from processing, and eliminates the need for manual QR code placement.
Common issues and solutions
Instruction pages generating errors: Add the IGNORE QR code before scanning.
Mixed single/double-sided scanning: IGNORE codes help manage blank reverse sides automatically.
Test your setup with a small batch first, ensure QR codes are clearly visible after printing, and train staff on which pages should have IGNORE codes. This system gives you complete control over which pages are processed while maintaining efficient batch scanning workflows.
