If the scanner is not scanning the entire page, there are a few troubleshooting steps you can take.
1. Make sure that the scanner is connected to a power source.
2. Check the settings on the scanner to make sure that it is set to scan the entire document.
3. Clean the scanner glass and check for any obstructions that could be blocking the scanner’s view of the document.
4. Change the resolution settings on the scanner to a higher setting.
5. Make sure that the document is placed properly in the scanner for optimal scanning results.
6. Make sure that the document is not too large for the scanner to handle.
7. If the problem persists, try using a different scanner or scanning the document in smaller sections.
