@DJM123, Welcome to HP Support Community!

I see that you have issues with scanning, I am assuming that you are scanning to email, follow the steps below-

Update the printer firmware

Download available firmware updates from the HP website

With the printer on and connected to the computer, go to HP Customer Support - Software and Driver Downloads, and then identify your printer. Look for and install any available firmware updates. Refer to the document HP Printers - Updating or Upgrading Printer Firmware

Assign manual IP to the printer

The steps on how to set a manual IP address can be found here.

For the DNS servers please use 8.8.8.8 for the Manual Preferred DNS Server and 8.8.4.4 for the Alternate DNS server. These are Google’s public DNS servers.

Try scanning.

If the issue persists, I'd like to know the following-

What happens when you make photocopies on the printer?

Are you able to print to the printer?

What happens when you try to scan from the computer?

Keep me posted for further assistance.

Thank you for your suggestions.  Last time,  I tried to download the latest software through my WiFi, and I encountered an error  downloading it to the printer.  But maybe I need to have my laptop physically  connected to my printer through some sort of cord.

Yes, a USB cable could be used to update the printer firmware once downloaded to the computer.

Keep me posted for further assistance.
