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.

Hi there!
If you're getting the error code B200 when you try to print on your Canon PIXMA MX850, there is nothing you can do except to have it repaired. This error code indicates a Voltage High Error of the Canon printer. If the printer is still under warranty, please contact Canon for further assistance.

I can not do anything on my printer. When I turn it orn the Error Code B200 is flashing on the printer screen. I need to know how to get rid of this code.

That error code is not listed on the known error codes for that model. Something to try is to turn off the machine, unplug the power cord from the power supply for five minutes. Plug the cord back in and turn on the machine. Give that a try and see if that fixes your problem. Otherwise I would suggest contacting Canon customer support at 1-800-OKCANON. Take care & good luck!

What is error B200 on Canon MX850?

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:
    • Unplug the printer
    • Manually slide the carriage over until you can get the ink cartridges out.
  2. Remove the ink cartridges from the print head.
  3. Use cotton swabs dipped in hot water or a mix of hot water and alcohol to thoroughly clean the print head.
  4. Repeat this until there is no ink residue coming off on the cotton swab
  5. Allow to dry and replace the cartridges
  6. Try to print something

If it doesn't fix it then the board inside of the printer is faulty and you will have to replace the printer

Canon Printer Pixma MP540 with error code B200 - what can I do? Thank you for your support. Arthur

Try to press down on the sponge to get it to work again. It may be a waste toner issue, which generally is repaired at an authorized service center for canon by contacting 1-800-OK CANON or logging on to

Good luck on this.
