What does E7 mean


  • E7 - Scanner locked error
    1. Turn the scanner off then move the lock switch to the "Unlocked" position. The lock switch is located on the left side of the scanner.
    2. Plug the power for the scanner directly into the wall, not in a surge protector or battery backup

Hello, I have a Canon MP810 printer and the screen shows there is an error with that number: 5020. It says that I have to unlock the locker of the scanner and then restart. I have done it many times...


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.

Error light on and saying scanner error


Hi!

Open the Lid for scanner, check for a switch on the side for Scanner Lock. Try to switch it to unlock position and retry booting up Printer. That should take care of scanner error message.

Hope this helps. Cheers!

Solution: Unlock the scanner lock switch

The scanner must be unlocked before turning the unit on.

Turn off the power.

Lift the document cover.

The scanner lock switch is on the left hand side of the underside of the document cover.

Slide the scanner lock switch to the release mark (an open padlock icon).

Lock the switch before transporting.

Close the document cover.

Turn the machine on.

If machine still is not working repeat the power off / on cycle waiting 5 seconds in between.

SCANNER ERROR 12


Not sure if this particular model has a scanner lock/unlock switch for transporting but I would definitely check for the switch either on the side of scanner or underneath the scanner and make sure it 's not in the locked position.

My 5800 keeps telling me to unlock it when I click scan, but I can't find the lock anywhere.


The 5800 scanner does not have a physical lock switch. DO NOT attempt to open the scanner and unlock the hardware. This could be either a hardware failure or software
Toggle the lock switch on the scanner leaving the switch in the unlocked (open padlock) position.
Ensure you are using the correct power supply for your scanner. If you are using a power supply that has the incorrect DC output, you will get a scanner locked error message. This flatbed scanners has I believe 100-120V AC input and 12V DC output.


Plug the power directly to the wall, not a UPS battery back-up, power strip or surge protector. Power fluctuations from a UPS battery back-up, power strip or surge protector may be causing this error. If all this fails try reinstalling the scanner driver

Error message says: Scanner is locked, Computer cannot communicate with scanner.


Have you checked the obvious? The scanner lock switch is located on the bottom of the scanner back right corner. --Ted
