Re: canon 8400f will not power up
I know this sounds stupid, but did you make sure to switch the power switch to the ON position? When the power is connected, and then you flip the power switch on, the light inside the scanner will illuminate, possibly briefly but noticeable. If that doesn't happen, then you're not getting power. Try different outlets. Re-secure power cord connection. If still no power, then I suggest to contact Canon (techsupport) for another power cable.
a 6ya Technician can help you resolve that issue over the phone in a minute or two.

I have many years experience repairing Canon scanners so here is my suggestion for you.
I guess I have a couple of questions for you first. Does your computer recognize the scanner is attached to your computer? If so can you scan in any other program like Windows Paint? If you say yes to both of these then the problem is with configuring your adobe software. If you say no then we need to go back to basics. I would google Canon Canoscan 8400F Drivers, it should pull up a page that will take you to Canons official website. Download the latest drivers from Canon's official website,the drivers are dated and the ones towards the top should be the latest drivers. The drivers are free. Also while your there download the newest version of Capture Perfect its a utility program for scanning its free also but download the latest one. Now make sure your scanner is unplugged from your computer, the cable that goes from the scanner to the computer. Install the latest drivers on to your computer. Once they are installed, then with your scanner powered on attach the cable from the scanner to your computer. A window should pop up saying a new device (or drivers) is being installed. Once this completes reboot your scanner and you should be able to scan again.
I use Paint shop and in order for me to scan with my Canon scanner I need to go to aquire and image, from a scanner or camera, and then it controls the scanner and does the scanning for me.
First, make certain that the flatbed scanner lid is securely shut.
Second, unplug the power and USB cables from the rear of the scanner.
Third, deposit the Canon 8400F scanner in the nearest garbage receptacle where it belongs.
Hope this helps.

Open the CanoScan Toolbox.
Click the Save option.
Put a check in the box that states "Display the Scanner Driver".
Click the Advanced Mode tab.
Make sure Select Source is set to "Platen".
Click the Preview button at the top left.
If the error still occurs, then most likely it will be a service issue.
One thing to check...see if the inside lamp illuminates when you turn the scanner on using the power button at the back left side of the scanner.
