Indicator light is on but printer will not turn on

HP Recommended
HP Office Jet Pro 6978

My printer was working fine yesterday. Today when I went to print nothing happened. The power light was off.  I checked to make sure the power cord was plugged in securely. I made sure there was power to the outlet. The indicator light on the back it on.

 

Any suggestions?

Thanks.

Hi @TOMandJennifer,

 

I'd like to help with the printer power up issue.

 

Try the below suggestions-

 

Step 1: Reset the power module and test the wall outlet

Unplug the printer to reset the internal power module, plug another appliance into the wall outlet to test the power, and then reconnect the printer.

  1. Disconnect the power cord from the rear of the printer.

  2. Unplug the power cord from the wall outlet, power strip, or surge protector.

  3. While the printer is unplugged, plug another appliance into the wall outlet, and then turn it on to make sure the outlet works.

    • If the wall outlet does not work, plug the printer into an outlet that does work. Do not use a power strip or surge protector.

    • If the wall outlet works, continue with these steps.

  4. After the printer has been disconnected for at least 60 seconds, reconnect the power cord to the rear of the printer.

  5. Plug the power cord directly into the wall outlet. Do not use a power strip or surge protector.

  6. Check the rear of the printer and the ink cartridge access area to see if the internal power module has an indicator light.

    • If the internal power module has a light, the light is on, and the printer turns on, you can stop troubleshooting.

    • If the internal power module has a light and the light is on, but the printer still does not turn on, continue to the next step.

    • If the internal power module has a light and the light is off, skip to the step to Test the power with another compatible power cord.

    • If the internal power module does not have a light, continue to the next step.

Step 2: Test the printer Power button

Plug the printer into a working wall outlet, and then test the Power button on the printer.Make sure the power cord is connected to the rear of the printer and is plugged directly into a wall outlet.

  1. Press and release the Power button to start a Power On/Off cycle. Do not hold the button down.

    NOTE: 

    If you press and hold the Power button too long, the printer might turn on and then off without restarting. If this happens, press and quickly release the Power button again.

  2. If the printer does not turn on, wait 10 seconds, and then press the Power button again.

Step 3: Test the power with another compatible power cord

 

Hope this helps! Keep me posted.
