The message to repair my MX850 with a B200 error code was to first remove and replace the ink tanks.  When I open the top the module that holds the ink tanks remains on the far right of its track where the tanks cannot be accessed.  Normally when I lift the lid to replace a tank, this module moves to the center where it can be accessed, but it is not doing this.  Suggestions?

This is the same generic answer that Tech Support sends.  Would be nice if Canon's error logic would be more specific.

My MX860 was getting this error and I tried all the suggestions for cleaning the printhead without success.  Since I actually like this priinter and it is setup for my windows and Linux, I took a chance and found a new printhead on EBAY for $50.  This fixed the problem.

Same for me. I looked elsewhere and found other solutions. I soaked the print head in warm water until it ran clear. Dried the unit for 15 hours, unplugged everything. Reinserted the printhead, ink cartridges, power cord, USB connection. Started unit and it worked. How long, I have no idea, but it saved me some money.

I am having exactly the same problem as Rick. Tried turning the printer off and unplugging for ten minutes. When I plugged it back in and turned it back on, the error code immediately returned. Now What?

[almacholtz]

did you take apart the print head before soaking it in warm water?

[zpuskas]

A day or so later, the unit stopped again. I bought an Epson.

Okay; did all of those steps twice.

NADA, no good, still get flashing alternate between orange alarm light and green copy button.  Does it 10 times then repeats.  Where's decoder to identify what 10 consecutive flashes mean?
