I have three HP 8710 printers. The primary put in printer, printer assistant encompasses a scan choice, the second put in printer, printer assistant has no scan choice. once I uninstall and transfer once more I swap printer positions and currently the second printer has the scan choice whereas the primary printer has no scan choice. 

Either printer reports a 2 scan error once loaded in second place and provides no scan choice. HP print and scan doctor reports 2 error and ultimately recommend uninstall and new transfer and could be a positive feedback with without stopping. however do I format so each printers add hp printer assistant as they each should?
