I have a client that has a Canon ImageClass MF4350d connected to a computer running Windows 7 Professional. The printer is not sitting next to the computer and needed a 15 foot USB cable to connect to the computer.
Well there was a strange problem that I had never seen before and wanted to know if anyone has run into the same problem.
The problem was when you used a 15 foot or longer USB cable to connect the printer. The printer would print perfectly fine but it refused to scan anything. It would freeze any program you tried to scan from. I tried about 10 different USB cable all with the same result. Multiple brands and multiple lengths of at least 15 feet.
I did get the printer working perfectly fine but I needed to use a 10 foot USB extention cable (Male\Female)with a 5 foot USB cable in order to get it working.
If anyone has had a similer problem let me know.
