    Same problem, turning the scanner on, when it's ready the scanner light suddenly starts to move a bit, which it shouldn't be doing at that time and then it says 'scanner error' in the dusplay. Have tried turning on and off, pulling the plug etc, nothing helps.

    Pixma MP780 won't scan or copy. It prints fine. When trying to scan is make a horrible sound like rivoting. Cannot see any light coming from it either. It appears to work but doesn't scan anything. Copy mode goes thru the motions but won't pick up what it copied.

    Any help would be appreciated.

    Thank you.

My Canon MG8120 all-in-one makes a loud noise when copying (not when printing). How do I fix it?


Dear
from the question I understand, the scanner move to right and during return it starts noise.

The problem with scanner assembly, It might be dust accumulated on gears, the scanner belt might have loose or the grips of the belt has worn out. Proper cleaning and lubricating the moving parts may overcome also if the belt worn out it has to be replaced.
In case of at home position it gives noise then the home position sensor may dirty/dusty, it has to be cleaned.

thanks.

Right now, the scanner bar is stuck to the far right and it makes a loud noise like gears slipping. But I would also like a copy of the "Service and Repair Manual" for any future problems.

Canon pixma mp780 auto feed does not print


You probably need a new printhead, but that problem cann also be caused by the purge or cleaning station not working properly. If you do a cleaning cycle with no carts. and the little pads in the printhead come back with no ink on them then the purge is working and you need a new printhead.

Canon PIXMA MP780 All-in-One Printer, etc.


Is this scanner installed onto a Vista computer?

In some cases the scan button may not operate without a memory resident program installed.

It will work by selecting my computer and selecting the scanner on the window. By double clicking on it, it will scan whatever is on the glass.
