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.

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. Yes we have read the user's guide.

For some reason no matter how many times I attempt to uninstall and reinstall this software the twain driver is not recognized by my computer. I keep getting a message saying, 'Unable to connect to device or Twain driver is not installed' I have even been to Lexmark's website and downloaded a driver specifically for the scanner. Has anyone ever heard of this happening? It is very frustrating and at this point my husband and I are going to have to get rid of this brand new printer we bought because we cannot get it to work. If anyone has any further tips I would appreciate it. I have tried that before, but I tried again and it says my printer's firmware is up to date. Two questions: 1.

At notice at lexmark's webiste they also have a universal printer driver. Do you think it would help to uninstall my driver and then reinstall a universal driver instead? When we originally talked to tech support at Lexmark they thought the issue was caused by our firewall or security software blocking some components of the installation. However, we have reinstalled the software several times with our anti-virus and firewall disabled. I am wondering though if it might be possible that our router is blocking something. Don't routers sometimes come with firewalls, or act like a firewall?
