Unwanted Lines

I have an Office Jet Pro 7740. Lately I am getting one mystery line through the middle of my scans and when I copy. What's up?

Hello, and Welcome to the HP Support Community!

 

Try looking at this tutorial on cleaning the scanner glass: https://support.hp.com/us-en/product/hp-envy-7640-e-all-in-one-printer-series/6617267/document/c0534...

 

Most likely there is a piece of paper stuck on the skinny slit of the window that is used by the Automatic Document Feeder.
