Hi I have tried to switch the printer on but no luck

I changed the fuse in the plug no change 

changed  the cable still no power 

It worked yesterday I printed and I used the scanner but I had to change the WiFi as I had changed suppliers 

now it won’t even switch on, not sure if there is a reset button anywhere or what else I can check

Hey @MammaJLloyd, 

Thank you for your response 😀.

Here are a few steps you can try since your printer is not powering on:

Check Power Connection

• Confirm Power Source
• Ensure the power cable is securely plugged into the printer and the wall outlet.
• Try a different wall outlet to rule out a faulty power source.
• Avoid using a power strip or surge protector; plug directly into the wall.
• Check the Power Cable & Adapter
• Verify that the power cable is undamaged.
• If the printer has a power adapter (brick), check for any loose connections.
• Try using another compatible power cable if available.

Perform a Power Reset

• Unplug the printer from the power outlet.
• Disconnect all cables, including USB or Ethernet, if connected.
• Wait 60 seconds (press and hold the power button for 10 seconds to discharge residual power).
• Plug the printer directly into the wall outlet and try turning it on.

Check for Signs of Life

• Does the power button light up or blink?
• Any noise (fan, clicking, or beeping)?
• If the printer briefly powers on and then shuts off, there may be a hardware issue.

Check the Power Button

• Press and hold the power button for at least 10 seconds.
• Try pressing it multiple times.
• If the button feels stuck, gently clean around it with a dry cloth.

 Check for Internal Printer Errors

• If the printer was updating firmware or settings when it lost power, it could be in a firmware corruption state.
• Try a firmware recovery by checking HP’s support page for firmware restoration steps.

I hope these steps help resolve the issue
