HP scanner will still send a scan to my windows computer, but after scanning a doc & then clicking send - this error msg appears... "the HP scan application is unable to open your email application and/or cannot attach the scan to a new email. please check your email configuration and try again." After running a HP print scan doctor 5.1 a "driver check" is X'd. Instructions are to unplug and restart which I've completed. "the scan driver is unable to communicate with the product"...
