CanoScan LiDE 400 install stalls - waiting for Scanner w/o power key to turn on

Greg-Boston — Wed, 08 Oct 2025 20:28:35 GMT

Downloaded the driver and waiting till it told me to plug in the USB cable - which I did. Then install STALLED waiting for me to power on via a switch that does not exist on the LiDE 400. Instructions were to remove and then reinstall the usb cable - which I did. Then I was instructed to restart the install. Keeps stalling in the same location w/o doing much. This must be very common for the LiDE 400 without a power switch.

Hi,

Based on this type of issue, I recommend reaching out to Canon support. You will need to register your Canon gear HERE to access additional support options.

We look forward to hearing from you

Was there ever a resolution to this issue?

I am experiencing the same problem. The install hangs on Step 3 once it has recognized the presence of the scanner.

I am running Windows 11 Home on a Dell XPS 17 9730 laptop with 13th Gen Intel Core i9-13900H (2.60 Ghz) processor and 32.0 Gb installed RAM. I checked to verify that no Windows Updates are running.

I have tried this several times with the same result. I have to click 'Troubleshooting' and then click 'Cancel'. When I look at Installed Apps, I see 'Canon IJ Scan Utility', 'Canon Inkjet Printer/Scanner/Fax Extended Survey Program', and 'CanoScan LiDE 400 Scanner Driver' listed, BUT... there are no file sizes associated with any of these allegedly installed apps.

If there is no resolution to this issue yet, does anyone know how best to get ahold of someone at Canon for support?

Greetings ,

Are you waiting to plug the scanner in until prompted to do so by the installer?

Do you have any third party antivirus installed?

You don't need to mention Windows Defender. It's native and included with Windows.

You can use the link in Hector's post above. To receive support, you'll register your product and it will give you support options. The telephone number for Canon support is 800-652-2666, but you'll need to register your product first.
