Hello Penelope,
The Canon TS3600 series supports scanning, but the function depends on having the correct driver and utility installed on your computer. Printing works because the basic printer driver is already in place, but scanning requires the Canon IJ Scan Utility. Without it, the printer cannot initiate a scan to the PC.
First, confirm that you have installed the full driver package from Canon’s support site, not just the print driver. The package includes the IJ Scan Utility, which is located under C:\Program Files (x86)\Canon\IJ Scan Utility\SCANUTILITY.exe. Launching this application should allow you to scan directly from the computer.
If you want to scan by pressing the button on the printer itself, you need to configure the scan destination in the Canon IJ Scan Utility. Open the utility, go to Settings, and under “Scan from the Operation Panel,” set your computer as the target. If this is not configured, the printer will not know where to send the scanned file.
Also, ensure that Windows Image Acquisition (WIA) service is running. You can check this by opening services.msc, locating “Windows Image Acquisition (WIA),” and confirming it is set to Automatic. If this service is stopped, scanning will fail even if the drivers are installed.
If you are using Windows 11, you can also test scanning through the built-in “Windows Scan” app from the Microsoft Store. Once installed, open it and check if the TS3600 is detected as a scanner. If it appears there, scanning should work without issue.
