I have a Canon TR4722 and I have a laptop running Windows 11.
I am unable to use the "scan" feature using wireless. I can print just fine using the wireless, but not scan.
This morning, the printer told me to update the firmware. I did so update the firmware on the printer. It was after updating the firmware to version 1.040 that I am no longer able to use the scan function via wireless.
If I run the Canon Wi-Fi Connection Assistant, it says it cannot locate the printer, but I can print a document just fine.
If I try to use the Canon IJ Scan Utility, if gives me the codes "Canon 5,157,69"
I have tried resetting the printer, unplugging both the router and printer, disabling all of my security features. Nothing works. I do NEED the scan feature. The wireless scan feature that allowed me to scan multiple pages at a time was a big part of the reason I bought the scanner/printer.
I don't know what else to do... like I said, I didn't have this problem until I updated to the latest firmware on the printer this morning.
Based on the steps you have already taken, I recommend reaching out to Canon support for this issue. You will need to register your Canon gear HERE to access additional support options.
We look forward to hearing from you.
