My MP830 all in one ink jet printer is having problems...It says release the scanner lock switch and turn power off and back on. I have tried five times, I have unplugged it from the wall also leaving it...

Open the scanner cover so you can see the platen glass. Now look on the left side of the glass, and you should see a sliding switch, probably blue in color. Move the switch to the icon that shows an open padlock (unlocked position).

Greetings, I have a Cannon MP830 all in one printer . . . yesterday I set it to make two copies--I was low on ink, but as I always let it run until it is empty before replacing the ink, I hit OK to by-pass...

Double check to make sure all the cables are securely plugged in. There is also probably a switch in the back of the printer, usually by where you plug in the power, that you might want to check. otherwise, unplug it and plug it into another outlet just to make sure the outlet on the power strip isn't bad. You may also want to try completely unplugging it from both the wall and computer, and then just plugging the power back and then the computer if that helps.

Good luck, let me know if it still doesn't work,

I have a Canon MP830 and I cannot turn it on when I touch the on off switch nothing happens I have checked all the power sources and they are plugged in; any suggestions?

1. If your MP830 is plugged into a power surge / power strip, power off/on the strip.

2. Plug the MP830 directly into the outlet.

3. Disconnect the power cord and wait 5 minutes before connecting

4. Replace the MP830 printer power cord.

5. Have the MP830 serviced.

Hope this helps.

It will not turn

Try leaving it unplugged for 1 hour plug it back into a different wall outlet and the power supply should then come back to life. If not take it to a canon service center.

To might great relief my MP830 powered up and is working just fine.
