We have a F 6130 scanner. We are receive an error DS42005 and DS42008 message to replace a specific roller. How do I get rid of the pop up? It pops up everytime we attempt to scan a document. And ...where do I order the part from and is it easy to replace or will I need to have it serviced by a tech? serial No: 139007, Date: 2009-11Thank you brenda@askmdpa.com
