My computer displays update required message and wifi won't connect. Have used smart app to no avai.

[RudyS27]

My printer dispkay indicates that an Update is required.

It further displays the following, "A problem has occurred with one of the printer's critical system files. A printer update will be installed to fix the problem". Unfortunately, the wireless can't connect because we got a new router and wifi password is different so printer can't connect. Also, the printer seems to be locked up because none of the buttons function. I have unplugged it, used hosmart app, hp printer scan diagnostic app all to no avail. What can I do to fix it?

Hi @RudyS27 

Welcome to the HP Support Community! 

Thanks for posting your query! We're here to help you get back up and running.

When you change your router or Wi-Fi password, you need to reconnect your HP OfficeJet Pro 8210 Printer to the new network. 

Here’s how to fix it:

 

Step 1: Restore Network Settings on the Printer

Press the Wireless button on the printer’s control panel or navigate to Setup > Network Setup.

Select Restore Network Settings to clear the old Wi-Fi connection.

 

Step 2: Reconnect to the New Network

There are two primary methods to reconnect the printer:

 

A. Wi-Fi Setup Mode (Recommended)

Press and hold the Wireless button on the printer for about 5 seconds until it starts blinking. This puts the printer in Wi-Fi setup mode.

Open the HP Smart app on your smartphone or computer.

Tap "Add Printer" and follow the setup instructions to connect it to your new Wi-Fi network.

Enter the updated Wi-Fi password when prompted.

B. WPS (Wi-Fi Protected Setup) Button (If Supported by Your Router)

Press and hold the Wireless button on the printer until it starts blinking.

Press the WPS button on your router within 2 minutes.

The printer should connect automatically.

 

Step 3: Print a Network Configuration Report

On the printer, navigate to Setup > Reports.

Print a Network Configuration Report to confirm the printer is now connected to the new Wi-Fi network.

 

Step 4: Reinstall the Printer on Your Device

If your computer or mobile device doesn't recognize the printer after reconnecting it to the Wi-Fi, remove the old printer configuration:

On Windows: Go to Control Panel > Devices and Printers, remove the old printer entry, and re-add it.

On macOS: Open System Preferences > Printers & Scanners, remove the old printer, and add it again.

On smartphones, re-add the printer via the HP Smart app.

 

Step 5: Check for Firmware Updates

HP regularly releases new firmware versions for printer enhancements, app updates, or issue fixes. Update the firmware regularly to get the most out of your printer.
