My Canoscan LiDE 400 worked fine until the latest Mac OS Update. I am currently running Mac OS 26.2 Tahoe and cannot connect to the scanner. The U Scan Utility Lite software says "searching for scanners" and ultimately generates the error message:
Cannot communicate with scanner. Possible reasons:
- Scanner is turned off.
- (If using wired LAN connection) It is disconnected from wired LAN.
- (If using Wi-Fi connection) Signal strength is poor due to obstructions.
- (If using USB connection) USB cable is disconnected.
Please check and try again.
I can hear the scanner so I know it's on. It is connected via USB and I have checked and rechecked the cables. I have deleted and re-installed the Canon application - none of these things have worked. Any advice? This scanner was working great for me prior to this OS update.
