I have an HP Envy 4507 and I can't scan. The computer and printer says they are not connected

[mellorcp]

My scanner says it can't connect to the computer when I try and scan.  The computer also says scanner/printer is not connected. This has only happened recently.  I also have issues printing from my computer.  The computer is a HP Pavilion.

@mellorcp, Welcome to HP Support Community!

This could be due to the connectivity or the drivers installed. Let us try to isolate and resolve the issue. If the printer is connected wireless, follow the steps below-

You may need to instead go into your router settings and try changing the channel manually. Experiment with different channels to see which one works best.

Use HP Print and Scan Doctor

Download HP Print and Scan Doctor and run the program. It will automatically diagnose and fix any printer connectivity issues. 

For more information, go to https://support.hp.com/us-en/topic/printscandoctor

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

If the issue persists, I recommend you delete the driver and root level and retry, follow the steps below: 

1) In Windows, search for and open Programs and features 

2) Select your HP Printer 

3) Select Uninstall 

4) In Windows, search for and open Devices and printers 

5) In the Devices and Printers windows look for your HP printer. If you see it listed right-click on it and choose ‘Delete’ or ‘Remove Device’ 

6) Open up the run command with the “Windows key + R” key combo. 

7) Type printui.exe /s and click Ok. (Note: there is a space in between “printui.exe”

8). Click on the “Drivers” tab 

9) Look for the HP Printer driver. If you see it Click on it and click Remove at the bottom 

10) Select Ok 

11) Select Apply and Ok on the Print Server Properties windows 

12) Close Devices and Printers.

Use this link to download and install the new driver. Configure the printer.

Add a TCP/IP port.

1. Print a Network Configuration Report from the Printer Settings or Wireless menu.
2. Right-click your printer, select Printer Properties, click the Ports tab, and then click Add Port.
3. Select Standard TCP/IP Port, and then click New Port.
4. Follow the instructions to add a new port using the information listed on the Network Configuration Report.
5. Try printing.

Hope this helps! Keep me posted.
