I was recently faced with this same problem, with non detection of the scanner N640P ex flatbed. It has a card for the parallel port connection and was installed by a computer repairer to save me time. He said it worked, but when I got it home, it failed, even with the new driver added.
Here is what I did.
Check the ports in which are used for the scanner, mine was found to be LPT2, I changed that to LPT1.
(Be prepared to reverse these 2 if necessary).
I did a reboot and turned on the scanner and it showed it was there but refused to bring up the Toolbox to scan anything.
Next step, go the Microsoft and pick up this "Restore parVdm" this belongs in Windows System 32 and aids in the recognition of not only your scanner but other vital peripherals.
Its a microsoft fail when the parVdm does not recognise something.
I installed that as it comes down in .rar file, and rebooted, and all is working exceptionally well.
Will this work with any other OS? I have no idea. This worked for me on XP SP3 but parVdm also exists in Windows 7, 8 and Vista.

Sounds like you have the Shipping Lock on.
There is a lever to turn when you unpack your scanner.
This is used to lock the hardware in place while the device is being shipped so nothing shakes loose.
It needs to be unlocked when you have it unpacked and setup.

Look for a lever like this in the picture and turn it to the Unlocked position.

SOURCE: I hab Bought one USB-to-Parallel connector to

I have many years of experince repairing Canon scanners so here is my suggestion.

First off I would go back to USB its faster then a parallel cable for scanning purposes. Second if your computer is a very old one then just get a usb card and install it in to your computer. Also make sure you have the latest drivers for the operating system your running. The drivers are free on Canons website. Just google Canon Canoscan N640P drivers it should take you directly to Canon's website also I would download capture perfect its free also an will function perfectly with your scanner.

When you install the newest drivers make sure your scanner is disconnected from your computer. Once the drivers are installed then attach the USB cable to your computer. You should get a message saying new drivers are being installed then reboot your computer and you should be good to go with whatever you want to scan.

I hope this helps you out.
