CanoScan LiDE 300 "Cannot communicate with scanner" error message


Hi, I got a Canon LiDe 300 about two months ago (running Windows 10) and it's been superb but after a few scans this morning I had an error: _____ Cannot communicate with scanner for these reasons: -Scanner is turned off. -USB cable is disconnected Please check and try again. Scanner driver will be closed. Code:5,156,69 __________ I've tried uninstalling, reinstalling, changing the cable, swapping USB ports etc. and nothing's changed it. No other software settings should have changed, it was working one minute and not the next. There's no sign of damage; any time I connect it to the PC it powers up and the arm moves, and the desktop reads it, it's just that that error comes up any time I click on any button on the IJ Scan Utility. Any help would be fantastic 😃

Hi, sorry, I'm running a PC with Windows 10



By chance are you running any 3rd party anti-virus software?  This would be something in addition to the included Windows Security.
