Question about Canon PIXMA MP830 All-In-One InkJet Printer
Scanner lamp won't light up. Error (Code 2,178,0) message comes up on computer.Also says scanner drives will be closed.
This problem sucks. It sounds like the scanner has actually gone bad. This can be a couple of things. The actual ccd unit inside the scanner, a position sensor, a motor or a wire harness.
The latter two are fairly unlikely, the first two more likely. Most probable is the CCD unit. I don't think Canon sells it as a separate piece, but it comes inside a replacement scanner assembly. These complete scanner units are expensive. You'll have to check with your local Canon shop to see what they cost.

SOURCE: Canon MP830 Error Code 6AOO
The error seems to indicate a failed sheet feed, check the paper path to see for any stuck bits of paper, however I have heard that this can also be caused by a flaky sensor in the paper path.....
apparently the best way to deal with this is to turn it upside down and give it a shake.
hope this helps

I had exactly the same problem (error Code:2,140,2) in Canon PIXMA MP250, and it was solved when I replaced both ink cartridges which were almost empty (almost without ink). I know an scanner problem is not supposed to be in relation with ink or printer problems, but that's the way I've fixed it. Good luck!

My Canon MP830 Scanner moves about 1/4 inch each time i turn it on, but will nothing will operate. The message reads, "Turn off and Unlock scanner" every time I try to use it. It was not locked. It worked fine for the 5 years I had it, now it moves just slightly each time I turn it on until it finally gets to the right hand side, then I can hear the belt skipping on the gear before it stops with the same message to turn off and unlock scanner, even though it is never locked. Any ideas? Other then tossing it out? Thanks, Chuck.
