Canon PIXMA MP140 Scanner not working in Windows 7

[shinystar77]

I have been having problems in getting the Scanner function to work properly in Windows 7. This is the message I receive everytime I try to scan or preview a scan in Windows 7:

Cannot communicate with scanner.
Cable may be disconnected or scanner may be turned off. Check status.
Scanner driver will be closed.

I have installed the latest drivers from the Canon Support website. I have even tried installing the latest Windows XP driver in Windows 7 with no effect. I have also tried using a different USB Cable and connected the USB Cable to a different USB Port on my Computer with no luck. 

The Scanner works fine in WIndows XP SP3. I upgraded my Computer to Windows 7 SP1 and now have a problem with the Scanner. 

Any ideas? It is supposed to work in Windows 7 I've checked the Canon and the Microsoft website which both say that its compatibie.

I have managed to get the Scanner working in Windows 7 SP1 64-bit after having carried out additional testing on my Laptop which has Windows 7 SP1 64-bit installed. 

The Scanner and Printer are working fine on my Laptop. I downloaded the 64-bit Drivers and MP Navigator 3.1 from the Canon Support website and installed it no problems and all is working okay there. 

However, I still cannot get the Scanner working on my desktop Computer running Windows 7 SP1 32-bit. It will only work on my desktop Computer when running Windows XP SP3. 

Any ideas anyone? I'm surprised no one has replied to me as this seems to be a common issue with Canon PIXMA printers.

This printer/scanner is NOT compatible with Windows 7 32-bit. 

I tried installing the latest MP Driver v1.06 and the MP Navigator 3.1 software in Windows XP compatibility mode and Windows Vista compatibility mode. 

I even tried using the MP Driver v1.00 and MP Navigator 3.1 software (provided on the CD-ROM that came supplied with the printer) in Windows XP compatibility mode and Windows Vista compatibility mode. 

I only had slight success with the MP Driver v1.00 which comes supplied on the CD-ROM with the printer.

When I installed this driver in Windows XP compatibility mode, it wouldn’t scan in MP Navigator 3.1 at all but in Windows Fax and Scan it would let me preview a scan then complete a full scan. But would then refuse to preview or scan anything else after that unless I turned the printer on and off and restart the computer. 

This is obviously a driver compatibility problem with Windows 7. 

I’m amazed at how Canon has tried to pass this printer/scanner off as being compatible with Windows 7 when it clearly isn’t. I know it works with Windows 7 64-bit but lets face it most people are using 32-bit systems not 64-bit.

It looks like there hasn’t been any proper testing done by Canon. Its poor form from Canon and the lack of replies in this thread is deafening. Seeing as this is the official Canon forum I was hoping there would be at least 1 or 2 replies saying try this and try that but I’ve tried everything there is to try at my end and I’m at a loss at what to try next.

I won’t be buying any Canon products in the future because of the poor after sales service and outright lies about compatibility of one of their products with newer Operating Systems. My next Printer/Scanner/Copier all in one will be an Epson or a HP.
