Possible Causes:

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.

What does error code E30 stand for in Canon printer MG 2120?

The E30 error means that the scanner unit either can't determine the size of the original or that the document is too small when "Fit-to-Page" copying is selected.

Check that your original is face down on the scanner glass (or face up if you have an automatic feeder). Also, check the position and direction of the original. You may need to copy the document without the "Fit-to-Page" option. Then copy the original in several sections.

I hope this helps.

I have just read it on the other forum..try this one
Error Code 5020:
Scanner lock switch locked. [5020] Release the scanner lock switch and turn the power
off and back on.
Turn the machine off, unlock the scanner lock
switch, then turn the machine on again.

Hope it helps.

Canon dr 7580 error code E30

E30 is a Error related to Exhaust Fan. Pls check if the Fan is working, replace if required. If the scanner was used in a dusty environment, the dust can clog the free movement of the blades. It may require cleaning.
