How to Fix HP Printer Scanner Not Working After Network Change?

The HP printer scanner not working after network change issue is common when you switch your Wi-Fi router, update network credentials, or move your printer to a new network. After a network change, your HP printer may still be connected to the old Wi-Fi configuration, causing scanning features to stop working even though printing may sometimes continue.

What Causes HP Printer Scanner Not Working After Network Change?

When you change your Wi-Fi network name (SSID), password, or router settings, your HP printer may lose communication with your computer or mobile device. Since scanning requires two-way communication, the scanner may stop responding.

Common reasons include:

Printer still connected to old Wi-Fi network
Incorrect HP Smart login account
Outdated or corrupted drivers
Firewall blocking scanner communication
IP address conflict after router reset
HP services not activated properly

Reconnect HP Printer to New Wi-Fi Network

The first step is reconnecting your HP printer to the updated network.

Steps to Reconnect:

Turn on your HP printer.
Reset wireless settings from the printer control panel.
Open the HP Smart app on your computer or mobile device.
Select Add Printer.
Follow the on-screen instructions to connect the printer to the new Wi-Fi network.

If your printer does not appear, restart both your router and printer, then try again.

HP Smart Login and Signup Setup

If scanning still does not work, ensure you are logged into the correct HP account.

Login or Signup Process:

Open HP Smart app.
Click Sign In.
Enter your HP account credentials.
If you don’t have an account, select Sign Up and create one.
Verify your email and complete account activation.

HP Smart login ensures your printer services are properly activated and synced with your device.

Download and Install Latest HP Printer Scanner Drivers

After a network change, outdated drivers may prevent scanning.

Steps to Download and Install:

Open your computer browser.
Search for your HP printer model.
Download the latest full-feature software and driver package.
Run the installer.
Select Wireless Connection when prompted.
Complete installation and restart your computer.

Installing the latest driver updates both printing and scanning services.

Update HP Printer Firmware

Firmware updates improve network compatibility.

To Update Firmware:

Install available updates.
Restart the printer.

Updating firmware often resolves scanning failures after router upgrades.

Activate HP Printer Scan to Computer Feature

Sometimes the “Scan to Computer” feature is disabled after a network reset.

Enable Scan to Computer:

Open HP Printer Assistant.
Click Scan.
Select Manage Scan to Computer.
Click Enable.
Save settings.

This ensures scanning functionality is properly activated on your system.
