The amount of pages that can be scanned at a time will vary on the scanner in use!
Please see the ADF amounts below:
- Pro - 100 pages
- 2nd Gen Original - 50 pages
- Compact - 20 pages
- Standard - 50 pages
Although that is the ADF limitation for each scanner you are able to scan more in one sitting by placing more documents in the scanner and clicking the "Add" Button in the top left hand corner of the page preview screen on the Original and Pro Scanners and you can also accomplish adding more pages on Raven Desktop by clicking the 
icon on the page preview page. Please note that anything above 150 pages has a higher chance of failing to send/receive due to file size. Please limit your scans to under 150 to avoid this.
Please contact support by emailing support@raven.com or by calling 1-800-713-9009 if you have any questions.
