Have new 8500A 910, set up three weeks ago, did great, print wireless, scans good, Turned the unit off for the weekend and when I pressed on today, still prints but when I try to scan error pops up saying HP Officejet Pro 8500 A910 was not found.  Yet I can still print??  I changed no settings, have rebooted twice, rebooted router and modem twice.  HELP
