Hi,

Thanks for using the HP Forums.

 

Can you power off and ensure the scan lid is closed and then power on again?

 

Do a scan as well as a copy job.  If the results are similar (with a vertical line), the scanner may be defective.

 

Hope that helps!

Hi @riz2

 

Does seem that the scanner is defective.  Do contact HP for a replacement.

On my 7740 I get a skinny black vertical stripe on auto-feed scans but scans on the bed are ok (clean).  I tried cleaning, restarting.  No change.
