Greetings,

This is a communications error.  We will need to know the OS and build you are using the scanner with.  What drivers you installed, and the steps, including troubleshooting you performed.  Please be specific and provide as much information about your environment as possible.   

Drivers for your product can be found here:

Canon Support for CanoScan LiDE 120 | Canon U.S.A., Inc.

Make sure you have unlocked the scanner lock switch before use:

Dear Sir, 

The scanner has been unlocked carefully and installed the new software properly. But not power even on. My laptop winddow 11. Pls explain me what does "Environment" stand for. Do you mean Room environment?

Greetings,

"Environment" in this case refers to the software and hardware you are using/operating the scanner with.

Operating system and build

Since this is a laptop, maybe you can share the make and model

How the scanner is connected and to what

Cable or hardware used

Installed software or driver used

Using in conjunction with windows or MAC you are safe.  It is supported under both operating systems currently.  The cable should be a high quality, shielded USB capable of power and data transfer.  It should be connected directly to an available USB port, and not through a hub, port / cable adapter or other interface.  Its important to install the correct driver and supporting applications (if applicable) for your OS, etc.  The USB ports on some laptops might not be able to supply enough power for the scanner.  Its pretty rare, but possible.     

Troubleshooting steps:

Was the correct software used for install

Is the cable connected directly between the two devices

Was the unit "unlocked"

Did you try another cable

Does the device power on when connected

Will it power on if connected to another computer

Does windows make a "detection" sound when its powered (is it recognized)?

Open device manager and look to see if the scanner appears correctly under the USB devices heading.  Is there a yellow triangle or error, etc.

These are the types of things, information and observations you would provide for us to try and assist you.
