To scan, you would need the Canon IJ scan utility installed onto your PC. It is the program that performs scans and interacts with the scan commands on the button panel of the TR4522. You can search your computer for the IJ scan utility to see if it is installed. If it is not, it would mean the software/drivers are missing and need to be installed. You would be able to fax without the driver installed and you can print using a generic driver but you need our drivers to scan properly. You can download and install the setup for our printer using the link HERE.
