Common problems HP Solution Center not working : Adobe Flash Player Error and Unable to scan
We would like to share some of the most frequently asked questions about HP Solution Center not working : Adobe Flash Player Error and Unable to Scan.

I'm using the HP Printer Assistant App to scan documents. 

When I use the Document Feeder, thin vertical lines are added to the scanned image. 

No lines are added if I don't use the document feeder.

Is there a solution?

The description of the problem sounds like the printer ADF needs attention (cleaning / maintenance).

 

If the dirt is on the outside..

Use a flashlight (torch in the UK); shine the light at an angle along the glass.

Clean, clean, clean.

Use a tiny brush to sweep all along the edges of the glass.

It wasn't a piece a paper.  I cleaned locations 3 & 2 and the lines disappeared.   Thank you.
