Scanner driver = ScanGear 64bit 14.0.3.45 Hello, I have similar problem as original poster, searched for solution on the internet and this looks most close to what I'm observing with my scanner. Thanks everyone for sharing your Informations. If anyone should come up with changes in drivers, or changes in backwards compatability with W7 64 for this particular problem, i would be interested. I am going to use it like this, and hope it doesnt come up with any more weirdness, In XP even with WIA off, using just the twain, this scanner had been problem free for years. It is using a twain, but another stange thing , If there is no WIA connection, how does the hardware buttons on the scanner 'scan copy PDF e-mail' function still? on the Xp system these items would only function if the WIA service was Strange I didnt replace it ? I didnt change the drivers.Īll I did was not believe the error, and persists against the Odd. Previews fine, scans full res fine, acts like nothing has happened. Out of the blue after retrying it a few times with the cano-scan and its scangear CS scanner pannel, it just works Fine. When clicking on the Scanner in the control pannel 'Devices and printers' pictures section, I get 'you Need a WIA driver to use this device' Asumption, this isn't going to work EVER. When there is a deeper or intermittant issue. When running from the canoscan toolbox I got the error 'Cannot communicate with the scanner - check cable and connection.'īUT, i had this little flinker working just fine, when I was doing it's install I specifically tested it, the last thing i was going to do was believe it :-) or believe some MS error, the troubleshooter was useless again, as it often is I have a 8400, what I get is similar and different. Didn't we go through this with the downloads? Please install it from the Installation CD or manufacturer's website and try again. Onthe 'Devices and Printers' panel, the CanoScan appears BUT when clicked on an Exclamation point message appears saying: ! You need a WIA driver to use this device. Where or what is the 'Built-in Application'? B. ' Lamp lights then after ~2 min error message as in 2 above appears. Initiated scan using 'CanoScan' selected 'Copy' (also used 'File' for a second try) As before we get a pop-up Window saying 'scanning in progress do not open lid. Downloaded the Canon Software from your suggested site - It is identical to that on the computer. Scanner driver will be closed.' Under this message in a second window is another that says ' TWAIN data transfer error.' 3. Cable may be disconnected or Scanner turned off. The error message appears in a window with the title From ScanGuard CS 'Cannot communicate with scanner. The error message alwaws comes after the scanner fails to initiate the scan. The Canon Scanning software has always been used. There are no marks of any kind next to any item in the device Manager after plugging in the Scanner.
