Scanner issue with with documents put through the feeder only

[MsKitty2120]

I have a HP Officejet 6310 All In One 2 year old printer.  I have issues with printing and scanning through the feeder.  A horizontal black line has just within the last month or so.  I have had the printer for 2 years and never had the issue.  At first less than 30 days, I could not even scan.  Printing and copying all okay.  Then Best Buy contract for service I have fixed the scanning process, but the black line through the feeder for copying and or scanning continued.  Best Buy suggested to check out with HP or the community to find out if this was a hardware issue or a component needed.  Can someone suggest something.  Best Buy suggested the possibility of realignment of ???

Hi @MsKitty2120,

Welcome to the HP Support Community. 

I'd be happy to help you! 

I understand that you are facing issues with printing and scanning through the feeder.

Since you have already performed the steps through Best Buy and still having issues, this could be hardware. 

However, refer to this document to isolate the issue for copy-related issues.
