4120 prints fine on WiFi but does not scan and not recognized by Smart

[Gargoyl]

Hi, my Desk Jet 4120 on WiFi prints fine from MS Office programs, but does not scan, and actually is not recognized by Smart or any other scanning app, such as Windows Scan. The name shows but it does not connect. It did scan with HP Smart at the beggining, but the whole login process was sooo annoying that I stopped using it. I am on Windows 11, all updated including printer firmare. Help pls..? Thanks!

Welcome to the HP Community Forum.

I might not understand your situation.

Ignore whatever is not relevant...

If you can print using Word, that generally indicates that the Full Feature Software / Full Driver printer software is installed and functional.

If the full driver printer software is installed, the installation includes HP Scan.

Generally, if the driver is working, HP Scan works, too.  ?

What is wrong?

Possible ...

• Printer is not perhaps not fully connected to the network
• Full Driver Printer software is perhaps not connected, is corrupted, or is not set properly
• HP Smart needs to be Reset or Uninstalled / Installed (yes, I understand you don't want to use it)
• Windows Scan is likely failing due to other influences (network, for example)
• Unlikely, but can certainly "throw a wrench in everything" -- Windows Updates are needed, pending, stuck...

Suggestions...

First,

Restart everything, including the router that controls your network.

Basic Instructions - Install the Full Feature Software / Full Driver printer software

Preparation

• If the printer software is still / already installed, Uninstall the printer software  from Control Panel > icon view > Programs and Features > Restart the computer and log in – Reference Uninstall HP printer software and drivers

• >>> After the printer software is uninstalled, check that the printer is not still lurking in Devices and Printers.  If the printer is listed, Right-Click on the printer and "Remove" > Restart the computer and sign in.

Continuing...

• If using VPN, shut it off to install software.  NOTE >> If you don’t know what this is, you are not using a VPN – ignore this part.

• Reminder:  If using USB cable between printer and computer, disconnect the cable before installing software.  Later... Connect the cable when instructed (near the end of the installation procedure).

• Observation:  It is possible (assuming your Wireless Network is stable) that using a Wireless connection to install the printer software might work better than using an Ethernet Connection.   Personal choice - the Wireless connection method is recommended when you face insurmountable issues installing the software.

Installation

• Download and Save the Full Feature Software Web Pack installation package or the Easy Start Software
• Open File Explorer
• Navigate to the folder in which you saved the installation file  (likely Downloads)
• Right-Click on the installation package and “Run as Administrator”
• After the software is installed, Restart the computer and log in

If using Easy Start

• Skip any extra software / offers you do not want – Wording varies as does the number of times you have to “skip” or opt-out of various options.
• When asked, opt for "Full Software and Drivers" (exact wording might vary).
• Easy_Start_Full_Driver_2

• If, after the Full Software and Drivers option is selected, the installation terminates (suddenly stops and disappears – never comes back): Open your Downloads folder > Look for and Right-Click on the full Web installation package and “Run as Administrator”
