A scanner error generally means a defect or failure with scanner subassembly & replacing the scanner will resolve the issue. If you are a end user, I would suggest you to contact HP support for further troubleshooting & repairs.

This is manufacturing fault in the printer and while contact @ CC of HP and service center they do some upgrade to printer. Again it stopped working. HP policy is very poor, even the printer still under warranty as per their record but they blame to produce bill and left to run to and from.
Stop this non-sense and awkward service and behavior and making fool to customers and resolve your manufacturing defects.
