Unable to scan, getting error message "The HP Envy 4520 series was not found"

[Jane_S_11]

Printing and copying works fine but I'm unable to scan any document. Printer is connected to network, computer is connected to network. Scan to Computer is enabled. HP Print & Scan Doctor shows that printer is online and there isn't any problem. It suggests to install updates but I'm also unable to do so and I get an error about not being the administrator, despite being logged in the admin account on my computer.

When I try to scan, the following message appears on the screen of the printer:

"Incorrect scan. One or more of the following problems have blocked scanning: 

1. the connection to the computer has been lost. 

2. The scanning application on the computer is presently in use. 

3. There is no OCR application installed in the computer."

I'm prompted to check the computer for messages and I get "The HP Envy 4520 series was not found".

Already tried:

- Uninstalled and reinstalled printer software  directly from original CD

- Reset factory settings in the printer

Hi @Jane_S_11

Welcome to the HP Support Community. I'd be happy to assist you

Due to the current global COVID-19 situation, we're seeing an influx of customers coming in for support. We appreciate your patience.

Windows Image Acquisition (WIA) is a Windows service that helps communication between the computer and scanners. If WIA is not activated, scan jobs can fail.

• 1. In Windows, search for and open View local services .

• 2. In the Services window, scroll down the list and find Windows Image Acquisition (WIA) .

• 3. Look at the Status and Startup Type values.

  • If the status is Started or Running and the Startup Type is Automatic, WIA is running correctly. Skip to the next step.

    

  • If the status is Disabled or no status displays, right-click Windows Image Acquisition (WIA), click Properties, click the General tab, select Automatic from the Startup type dropdown menu, and then click Start.

    If the Start button is grayed out, go back to the Services menu, make sure Remote Procedure Call, Shell Hardware Detection, RPC Endpoint Mapper, and DCOM Server Process Launcher are running and set as Automatic, and then start WIA.

Try to scan. If the error persists, continue to the next step.

 Let's try and uninstall the printer software from the root level on your PC and install the full feature printer software.

--->In Windows, search for and open Programs and Features.

--->Select your HP printer.

--->Select Uninstall.

--->In Windows, search for and open Devices and Printers.

--->In the Devices and Printers window look for your HP Printer. If you see it listed, right-click on it and choose "Delete" or "Remove Device.”

--->Open up the run command with the "Windows Key + R" key combo.

--->Type printui.exe /s and click OK.

--->Click on the Drivers tab.

--->Look for HP Printer driver. If you see it click on it and click remove at the bottom.

--->Select OK.

--->Select Apply and OK on the Print Server Properties windows.

--->Close Devices and Printers.

And then reinstall the printer full-featured drivers from software and drivers page
