MP830 canon 3in1 scanner lock.

Check for the switch is it not jermed or check the switch contact is it not normally opened or normally closed for the full time.

This took me forever to find. Please let me know if it works.

I am not 100% sure on this but I do know that most printers and scanners when straight out of the box sometimes have tape or some foam that they use to keep the bits that move around from moving. I would check your manual from end to end and if you dont find anything in it then I would contact tech support for Canon as it may be that this is a bug of some sort that they may already have a fix for.

Issue: ERROR LCD: Release the scanner lock switch and turn the power off and back on.
--------------------------------------------------------------------------------
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.

The scanner lock switch may be in the locked position. Lift the cover and check the slide switch located on the top front left. If this is not the problem, you will have to have a service center look at the problem.

Please rate me.

the error message: "Scanner is not operating correctly." The scanner is definitely unlocked.

hi,

its next to the scanner glass, open the top up like you would copy and its there to the left

hope this helps

Do you not have a manual or 'get you started sheet?' It is the first thing you do when unpacking a scanner is to unlock the shipping lock. In all probability it is under the scanner base so if it is a lifting item[to access the printer] check there,or on the backplate of the scanner where all the sockets are. Failing that get onto the Tech support site at Canon.
