Hi @kensbarbra,

 

Welcome to the HP Support Community

I'd like to help!

 

I understand you are unable to scan legal documents

 

Follow the below instructions -

 

Install the HP Smart app (Android, iOS)

Install the HP Smart app on a mobile device running Android or iOS.

Place the printer near the Wi-Fi router if you are setting up a wireless connection.

Make sure paper is loaded in the main tray, and then turn on the printer.

Download the HP Smart app from 123.hp.com.

NOTE:

Disconnect from a Virtual Private Network (VPN) connection before downloading.

If you are setting up HP Smart for the first time, you must create or sign in to an HP account to access all printer functions.

Turn on Bluetooth to help locate the printer during the setup.

Open the app to set up the printer.

If the printer is found, follow the instructions to complete the setup.

If the printer does not display or to add another printer to the app, click the plus sign , and then follow the instructions to add the printer.

Use HP Smart scan options

Save, share, and send scanned documents with the HP Smart app in Android or iOS.

Scan with the HP Smart app (Android, Apple iOS)

Scan documents and photos from the printer, or capture items with the phone or tablet camera.

Select one of the following scan tiles from the HP Smart app home screen.

Printer Scan: Place the original on the printer scanner glass or into the automatic document feeder (ADF). In Android, tap the Settings icon to select the input source, resolution, and color, and then tap Close. In iOS, tap the dropdown to select the paper size, quality, and color, and then tap Done.

Camera Scan: Uses the camera on a phone or tablet to capture a photo or document that you can edit, print, or share.

Tap the Preferences icon toggle the enhancement features on or off, and then tap Done.

Select a preset option, and then tap Scan or the white circle to start the scan.

If an Adjust Boundaries or Detect Edges screen displays, tap Auto or manually adjust the boundaries by tapping and moving the blue dots, and then tap Next.

Select from the following options and settings in the Preview window.

Add another page by tapping + Add.

Tap and drag the images to reorder multi-page scans.

Tap the Menu icon to edit, replace, or delete the scanned items.

Tap the Rotate icon to rotate the item.

Select the file type, either Basic PDF to save as a single file or Image to save the scans separately.

In the Edit window, adjust or enhance the file by cropping, changing the color, rotating, or adding filters and text, and then tap Done.

Scan Edit screen

Select an option to save, print, share, or fax the scan file.

Print: Send a scan to the printer.

Save: The default save location for scanned documents is the Documents folder and the Pictures library for scanned photos. Save a scan in the default location or browse to a different folder.

Share: Send a scan in an email, share via social media accounts such as Twitter, Facebook, or Instagram, or save the scan in a cloud storage account, such as Box or OneDrive. You can also look for other apps in the Windows Store.

Shortcuts: Create or use an existing shortcut for printing, emailing, or saving scanned files to cloud accounts.

After saving the scan, tap the back button to return to the Home screen.

 

If the issue persists, Scan with the Mopria Scan app (Android)

Use the Mopria Scan app to scan documents or photos from your HP printer to your Android device.

Check the requirements to scan with the Mopria Scan app.

The printer is connected to your network or a Wi-Fi Direct connection.

For a Wi-Fi connection, the printer and Android device are within 6 feet of the access point (router).

For a network connection, your device is connected to the same network as your printer.

Go to Google Play - Mopria Scan to install the app. If prompted to allow the app to access photos, media, and files on your device, select Allow.

In the Mopria Scan app, tap your scanner under Discovered scanner.

Place the original on the printer scanner glass or into the automatic document feeder (ADF).

Change any desired scan settings, and then tap Scan.

Follow the prompts to complete scanning the document.
