Welcome to the HP Forums. I would be happy to help you with your HP Officejet 6500 printer. I understand that you are getting vertical lines while copying from ADF.
Don't worry though as I have a few steps to determine the issue and find a solution as well,
- Clean the scanner.
- Clean the ADF rollers.
- Change the copy settings.
- Change the paper settings.
- Reset the printer.
Click here and follow the steps mentioned in the document to perform above steps.
Let me know if that helps.
Cheers.
