MFP does not scan full page through ADF

[DanNeedsHelp]

I have a HP LaserJet Pro MFP M521dn that the scan image is getting cropped on all sides only when I scan through the document feeder. If I place a document on the glass, it scans fine. The document feeds through the ADF without any problems and always crops at the same place on all sides so the issue is not with the feeding mechanics. Seems like a setting but cannot find a place to adjust except I see a place to set scanning profiles. In the scanning profiles it does not have a paper size for letter. Not sure if that is the issue or not. I have tried updating the drivers, but have not be able to resolve the issue. HP Smart does not support this printer. The issue exists with a new Surface laptop recently purchased. The previous laptop did not have this same issue. Would appreciate any insight/suggestions. Thanks!

Hi @DanNeedsHelp 

Welcome to HP Support Community.

Thank you for posting your query, I will be glad to help you.

It sounds like the issue you're facing with your HP LaserJet Pro MFP M521dn scanner, where the scan image gets cropped when using the Automatic Document Feeder (ADF), could be related to a setting or configuration, as you've already ruled out the mechanical feeding problems. Since you mentioned the issue appeared with the new Surface laptop, it might be related to either software settings or driver compatibility. Let's go through some potential causes and solutions to fix this:

1. Check Scan Settings in HP Software

• Open HP Scan or HP Scan and Capture software (if you're using Windows).
• Look for any scan settings or Scan Profiles that might be adjusting the scan area. Specifically, make sure that the paper size is set correctly (e.g., Letter or A4).
• Ensure the scanning area is set to scan the full page. Sometimes, certain profiles or settings default to smaller margins that may crop the scan.
• If there’s a Preview option before scanning, try previewing the scan to check if the document is being detected correctly in the preview window.

2. Check ADF Paper Size Setting

The lack of a "Letter" size option in your scanning profile is a key clue. The scanner might be detecting the wrong size or a custom paper size.

• Ensure that the paper size setting for scanning through the ADF is set to Letter (8.5" x 11").
• You can check this within the HP Scan Profiles settings or any scanning software that you’re using.
• If you don't see a "Letter" option, manually adjust the settings to match the page size of your document.

3. Adjust the Scan Area in the Software

If the scan area is too small, it could be cropping the edges. You may need to manually adjust the scan area within the scan settings.

• Many scan programs allow you to adjust the margins, or you may be able to set the scan area to "Auto" detection, which will fit the scan to the document size.

4. Check for Surface Laptop Compatibility

Since this issue appeared after switching to a new Surface laptop, it’s possible that there’s a compatibility problem with the drivers.

• Double-check that you’ve installed the latest printer drivers from the HP website specifically for your HP LaserJet Pro MFP M521dn and your new Surface laptop's OS version.
• If you're using Windows 11, some users have reported scanner issues with specific HP models. Make sure the latest updates for Windows 11 and the printer drivers are installed.
• Sometimes, issues can arise from USB port compatibility or interference. Try using a different USB port on your Surface (preferably a USB 3.0 port) or connecting over Wi-Fi instead of USB to see if the issue persists.

5. Use the HP Print and Scan Doctor

HP provides a tool called HP Print and Scan Doctor that can help diagnose and fix printing and scanning issues automatically.

• Download and run the HP Print and Scan Doctor.
• It will help detect any issues with the scan process and potentially fix them.

I hope this helps.

Take care and have a good day.
