My husband and I recently purchased a Lexmark Pro 715 All-in-One Printer. We have Windows Vista 32 bit on our computer, but from the moment we installed the printer we have been unable to get it to scan. It will not scan from the menu on the printer, nor will it scan from Windows Photo gallery and in Picasa when I click on the Lexmark 710 series icon it says: "Unable to connect to device, please check the connection." We have uninstalled and reinstalled the printer software/drivers numerous times. We have been on the phone with Lexmark who said that our security software must be interfering with the connection and so we uninstalled and reinstalled with our security software off. We even had Lemark remotely access our system and they could not get it to work. It says that this is compatible with Vista, but if that is the case then why can I not get it to work from my computer? We need the scanning function for my husband's business and we are at our wit's end trying to figure this out. Tech support has no further suggestions for us. but thought someone here might have an idea what would help.
