Hp envy 4520 won't scan "connection required"

[Dave_Gi]

Help Needed: I have tried just about everything I can think of and looked up on the internet. But I can't seem to scan anylonger. Printing and copying works fine. I have tried the HP Print and Scan Doctor 5.1  fix scaning and says the scanning successful but not sure what that means or what happened to the scan. When I try to scan from the printer the error message is  "connection required" then gives me some instructions: 1) The computer is on; 2. the computer and the printer are properly set up on the same network; 3. The recommended HP printer software is installed and configured on the computer. Can anyone assist?

@Dave_Gi,

Welcome to the HP Forums!

Thank you for posting your query on this forum, it's a great place to find answers.

Don’t worry, I assure you I will try my best to get this sorted.

In order that I may provide you with an accurate solution, I will need a few more details.

• When was the last time the printer was working fine?
• Do you have the printer full feature software installed on the computer?
• From which software/application you are scanning?
• Have you made any software or hardware changes on the computer?
• Have you performed any troubleshooting steps before posting?

While you respond to that, I recommend you follow the below steps and check if it helps.

1.With the printer turned on, disconnect the power cord from the rear of the printer and also unplug the power cord from the wall outlet.

2.Remove USB cable, if present.

3.Wait for 2-3 minutes, press and hold the power button on your printer for about 30 seconds to remove any additional charge.

4.Now plug back the power cable straight to a wall outlet without any surge protector or an extension cord (This is important) and then plug back the power cord to the printer.

5.Turn on the printer and wait till warm-up period finishes and the printer is idle.

If you continue facing the issue, I recommend you follow the below steps.

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” and “/s”)

8.) Click on the “Drivers” tab

9.) Look for 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

13.) Restart the PC

14.) Download and install the printer software from the below link.

15.) Connect the USB cable ONLY when prompted and follow the on-screen instructions.

Let me know how it goes and you have a great day!
