Most scanner problems happen after Windows updates, driver changes, or when the wrong software is installed.
Table of Contents Common Causes
Here are the most common reasons why Canon IJ Scan Utility does not work.
The utility is not installed on the computer
The wrong printer driver is installed

The printer is not connected to the PC or Wi-Fi
The scanner service is not running

These problems are very common. This comes up a lot with home printers.
Now let's fix it step by step.
What is Canon IJ Scan Utility and why it is needed
Before we start fixing the problem, it helps to understand what Canon IJ Scan Utility actually does.
Canon IJ Scan Utility is the official scanning software used with Canon printers that have a built-in scanner.
We see this situation a lot. The printer works fine, but the scan button does nothing.
The utility allows your Canon device to scan documents, photos, and PDF files directly to your computer.
That is why reinstalling Canon IJ Scan Utility is one of the first things we recommend when the scanner stops working.
Fix 1 - Install the full Canon driver package
Sometimes people install only the printer driver, but the scanner needs the full package.
Step-by-step
Open Canon support website Drivers & Downloads section
Search your printer model
Download Full Driver & Software Package
Remove old Canon software from Windows
Install the new package
Restart the computer
This usually restores IJ Scan Utility. This happens often after reinstalling Windows.
Pro Tip:
Fix 2 - Check if Windows detects the scanner
If Windows cannot see the scanner, the utility will not work.
Step-by-step
Press Win + I
Open Bluetooth & devices
Click Printers & scanners
Check if your Canon device is listed
If it is missing:
Click a printer or scanner
Select your printer
Install the driver
Safety Note:
Fix 3 - Restart Windows Image Acquisition service
Scanning depends on a Windows service.
Step-by-step
Press Win + R
Type:
services.msc
Press Enter
Find Windows Image Acquisition (WIA)
Right-click → Restart
Try to scan again.
Real-world note:
Fix 4 - Reconnect printer or scanner
Sometimes the problem is just the connection.
Try this:
Turn off the printer
Unplug USB cable or disconnect Wi-Fi
Restart the computer
Turn the printer back on
Connect again
Open IJ Scan Utility
Simple, but it works surprisingly often.
