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 need to copy a piece from a music book, to mark it up for rehearsal.  The book is thick enough that I have to leave the cover up.  The first 6 pages copied OK, but now all I get is an alll-gray page.  The light bar does not move; it sounds like it's stuck, but only when the cover is up.  With the cover down (copying a single sheet), it works fine.

I figured it out!  The diference between the copies that worked and the ones that didn't was the size of the paper I was using to mask unwanted material.  For the ones that worked, the sheet extended over the light bar.

 

Apparently the light bar requires a white surface facing the flatbed, or it won't work.

Thank you so much for providing the solution to the non scanning problem, Top Student. I had almost given up and accepted all the answers that said the printer is now broken. Then I saw your solution, put some white paper over the light bar and am able to copy and scan!
