Hi TonyDWalker,
Welcome to the HP Forums, I hope you enjoy your experience!
I understand you are getting poor quality copies and when turning the printer on it prints a test page.
I will be happy to help you.
Make sure the printer is connected directly to a wall outlet. (don't use a power hub or a surge protector)
The printer requires more power when scanning and copying. This should also correct the test page printing at startup.
Here is a document for cleaning the glass.
Vertical Bands, Lines, or Streaks in Copies, Faxes, or Scans. Disregard the title.
Are you using Genuine HP Ink Cartridges.
Hope this helps.
Thank you for posting on the HP Forums.
Have a nice day!
