Welcome to the HP Forums. I would be happy to help you with your HP Officejet Pro 8600. I understand that you are getting vertical lines when you copy.
Don't worry though as I have a few steps to determine the issue and find a solution as well,
- Clean the roller in the ADF.
- Clean the scanner glass with a lint free cloth.
Click here for the video to refer and fix this issue.
