ADF doesn't work to scan documents

[8602]

The ADF does not work to scan documents.  Scans fine using scanner bed.  ADF works fine for copying though.

Hi @8602

Welcome to the HP Support Community. I understand you are not able to scan from the ADF. I'd be happy to assist you.

• Are you using a Win PC or a MAC?
• Which application are you using to scan?
• What is the error you get while scanning from the feeder?
• Does the ADF pick the paper while scanning?

The printer uses the same mechanism to copy and to scan. Try making a copy again from the ADF and check if that works.

Make sure to select the 'Document feeder' option in source while scanning.

Keep me posted for further assistance.

I am using a HP EliteBook 840 G4 with Windows 10.

When I try using the HP printer assistant installed on the device and I click on "Printer Home Page" and then "Scan" to open a scan menu I get a message that says "You cannot use this function because it has been disabled. For more information contact the person who set up the printer."  I am the one who set up the printer.  I have tried but cannot find how to enable this function.

I just tried again and the ADF works fine for copying but when I place something in it and tap the scan button on the printer it will only scan from the bed.

I have not been able to find anyplace that gives me the option to select the document feeder.

I purchased this printer in December last year (2019) to replace the one I had which was the same exact printer.  The ADF always worked fine on that one.

@8602, thank you for the detailed response.

It seems like the scanning feature has been disabled according to the message.

1. Obtain the IP address of the printer – You can touch the “wireless” icon on the printer control panel to obtain the IP address.
2. Type the IP address at the top of your web browser to obtain the printer EWS page on your computer.
3. If you get any security notification, click on show details/advanced and 'proceed to this website'.
4. Go to Scan > Try scanning and check if this works
5. Now, go to Settings on the same page > Administrator Settings > Webscan > Enable > Apply and Ok.

Now try scanning. If the issue persists, we will have to perform a factory reset on the printer.

Let me know how this goes.

That seems to have fixed it.  ADF is now working to scan.  I figured it was a setting I just couldn't find where/how to correct it.  Thank you!!
