The Canon Printer Won't Scan problem can be confusing when the copying function works normally. Although copying and scanning use similar hardware, scanning to a computer also requires communication between the printer, operating system, and scanning software.
If your Canon Printer Not Scanning even though copying works, the issue may involve network communication, scanner drivers, software settings, or computer permissions. This guide explains how to identify the cause and restore scanning.
Why Does My Canon Printer Copy but Not Scan?
When you make a copy, the printer scans the original document and prints it directly. This process usually does not require communication with a computer.
Scanning to a computer is different. The printer must transfer the scanned image through USB or a network connection.
Common reasons for scanning failures include:
The computer cannot detect the scanner.
The printer and computer are on different networks.
The scanner driver is missing or incompatible.
The scanning application is incorrectly configured.
Firewall settings restrict local communication.
The wrong scanner is selected.
A USB connection is unstable.
The scanning software lacks necessary permissions.
Because copying works, the scanner hardware is likely functioning at least for basic document capture. However, this does not completely rule out every hardware problem.
1. Check Whether Your Computer Detects the Scanner
A Canon Printer Scanner Not Working message may appear when your computer cannot recognize the scanning component of your multifunction printer.
Start by confirming that the printer is powered on and connected.
On Windows 11, open Settings > Bluetooth & devices > Printers & scanners and check whether your Canon device is listed.
You can also open the Windows Scan application, if installed, to see whether the scanner is available.
On Mac, open System Settings > Printers & Scanners and select your Canon device.
If the printer appears but scanning is unavailable, continue checking the scanner software and driver configuration.
2. Fix Canon Printer Won't Scan Over WiFi
If your Canon Printer Won't Scan Over WiFi, verify that the printer and computer can communicate on the local network.
A printer may successfully make copies while its wireless connection is disconnected or incorrectly configured.
Check the printer's network status and confirm that it has joined the correct WiFi network.
Make sure the computer is connected to a network that permits communication with the printer.
Guest networks and device isolation settings may prevent scanner discovery.
If necessary, restart the printer and wireless router, then try scanning again.
Avoid resetting all network settings unless basic troubleshooting fails.
3. Check Canon IJ Scan Utility Settings
The Canon IJ Scan Utility Not Working problem can occur when the application cannot locate the scanner or is configured for the wrong device.
Open the scanning application and review the selected scanner.
If multiple Canon devices appear, choose the correct model and connection.
For supported network scanning configurations, confirm that the appropriate network scanner is selected.
Close the application and reopen it after making changes.
If the scanner remains unavailable, check whether the installed version of the utility supports your printer model and operating system.
Not every Canon printer uses the same scanning software.
4. Install or Update the Scanner Driver
A missing scanner driver is a common reason for Canon Printer Not Scanning to Computer.
Your printer may work for printing while its scanning component requires additional software.
Identify your exact Canon printer model and operating system version.
Check whether a compatible scanner driver or scanning package is available for your device.
Install the appropriate software from a trusted source and restart the computer if required.
After installation, open your scanning application and test the scanner again.
Avoid installing unrelated drivers simply because they mention Canon printers.
5. Check USB Cable and Connection Problems
If you use a USB connection, inspect the cable and computer port.
A damaged cable or unstable USB connection can interrupt scanner communication.
Disconnect the cable and reconnect it securely.
If possible, try another compatible USB port or cable.
Avoid using an unreliable USB hub during troubleshooting.
Restart the scanning application and check whether the scanner appears.
If the printer can print through USB but scanning still fails, investigate scanner-specific software rather than assuming the cable is defective.
6. Review Firewall and Computer Permissions
Sometimes, the Canon PIXMA Scanner Not Working issue is related to computer security settings.
A firewall may restrict network scanner discovery, particularly when the computer is configured for an untrusted network.
Check whether your home network is recognized as a trusted private network where appropriate.
Review the permissions required by your scanning application.
On Mac, some applications may need permission to access particular files or folders when saving scanned documents.
Do not permanently disable your firewall or security software to enable scanning.
Instead, use the appropriate application permissions and trusted-network settings.
7. Try a Different Scanning Application
If your Canon Printer Won't Scan to Computer through one application, test another compatible scanning program.
On Windows, you can try the Windows Scan application if your scanner is supported.
On Mac, compatible scanners may work through Image Capture.
If scanning works in another application, the original software may be incorrectly configured or incompatible.
If no application can detect the scanner, focus on drivers, connection settings, and operating system recognition.
This comparison can help identify whether the problem involves the scanning application or the device connection.
8. Check Scanner Selection and Document Settings
Sometimes, scanning fails because the wrong scanner or scan source is selected.
Open your scanning application and confirm that the correct Canon device is chosen.
If your printer has both a flatbed scanner and an automatic document feeder, select the appropriate source.
For flatbed scanning, place the document correctly on the scanner glass.
For automatic document feeder scanning, load the pages according to the printer's instructions.
Also check the selected file format and destination folder.
An invalid save location can make a completed scan appear unsuccessful.

Frequently Asked Questions
Why does my Canon printer copy but not scan to my computer?
Copying works locally, while scanning to a computer requires compatible software and a functioning USB or network connection.
Why is my Canon printer scanner not detected?
The scanner may have a missing driver, incorrect network connection, incompatible software, or a device discovery problem.
How do I fix Canon IJ Scan Utility not working?
Check the selected scanner, confirm the connection, and verify that the installed utility supports your Canon model and operating system.
Can my Canon printer scan without WiFi?
Many multifunction Canon printers can scan through a compatible USB connection, provided the required scanning software is installed.
Why does my Canon printer print but not scan?
Printing and scanning may use different software components. A working printer driver does not always mean the scanner driver is correctly installed.
Final Thoughts
A Canon Printer Won't Scan problem does not necessarily mean the scanner is damaged, especially when the printer can still make copies.
Start by confirming that your computer detects the scanner. Then check WiFi or USB connectivity, scanning software, scanner drivers, and application permissions.
