How do you reset b200 error code on canon mx850 printer?

SOURCE: Error Code

Try keeping the paper only in the bottom tray (there's a tray in the bottom) Try pulling any paper out of the top and just close that top tray. Open up the head so that u can see the ink cartridges and turn the printer on and off and maybe it will center itself again. If it's still not working (even if lights aren't red and print head wont align in the center) try manually moving the head back and forth like 18 times so you can lubricate that rail in the back that's holding it. After that, re-turn it off and on again.

The B200 error is a Voltage High Error. I read that you should try using a different power outlet and see if that works and if that doesn't work try cleaning the print head:

1. Open the printer and wait for the carriage to slide over. If for some reason it does not follow these instructions:
2. • Unplug the printer
   • Manually slide the carriage over until you can get the ink cartridges out.
3. Remove the ink cartridges from the print head.
4. Use cotton swabs dipped in hot water or a mix of hot water and alcohol to thoroughly clean the print head.
5. Repeat this until there is no ink residue coming off on the cotton swab
6. Allow to dry and replace the cartridges
7. Try to print something
