HP Scan Diagnostic Utility Failed Windows WIA Scan & HP Twain Scan

Advertisement

Hello, I have a HP Officejet Pro 8600 Plus N911g installed as a network printer on my Windows 7 64 bit Home Premium.  I ran the HP Scan Diagnostic, and at first it failed the WIA Scan test, but the printer was at idle.  So I selected Scan in the touch panel to sort of wake it up.  Then it passed WIA Scan, but went on to fail the HP Twain Scan.  I checked my software and drivers and they are current.  As a side note, when I click Start > Devices and Printers, it takes two minutes to open the window, so some of this could be timeout issues.  All suggestions gratefully received!

Hi-

It does sound like you are having network connectivity / delay issues.   Have you ran the HP network diagnostic utility to see if it gives any help?
