Hi @Chongers

I understand that the ADF and the scanner bed is no working.

Try and make a copy with the lid up and check if the scanner bar lights and if it moves.

Reset the product

• With the printer turned on, disconnect the power cord from the rear of the printer.
• Unplug the power cord from the wall outlet.
• Wait at least 60 seconds.
• Plug the power cord back into the wall outlet.
• Reconnect the power cord to the printer.
• Turn the printer on. HP recommends plugging the printer directly into a wall outlet.

Let me know how this goes!

1. Scanner bar does not light or move  with lid up , paper on glass bed and copy pressed. Message is Feeder not able to pick up original and blank sheet comes out in front.

2. With lid down, rollers of ADF tray do not move to accept attempt to feed paper.

3. Several tries with plugs out and in, rollers cleaned, holding power button etc to no avail.

4. Is a cable or part to the rollers not functioning, need replacement or repair; or , need a new printer?

5. Thank you

It is a hardware issue, I'd suggest you Contact HP in your region regarding the service options for your computer.

If you are having trouble navigating through the above options, it's most likely because the device is out of warranty. If yes? please send me a private message with the region you are contacting us from. Check next to your profile name, you should see a little blue envelope, please click on it.  

Have a great day!
