Question about Canon Office Equipment & Supplies
Does anyone know what a E30 error means on a Canon 5020?
1. Faulty communication between the scanner and the computer
2. Insufficient power to the scanner
1. Disconnect and reconnect the USB cable from both the scanner and the computer.
2. Ensure that the USB cable is connected directly to the computer as opposed to connecting through a USB Hub or some other USB device.
3. Restart the computer
You might also try a different USB cable.
If the problem persists after performing the steps listed above, then the unit will most likely require service.
