I have the same error. I removed my ink cartriges and ink tank holder. I then started to get a message that I had the wrong holder and it needed to be replaced. This is the very first problem with my printer and I have had it for years. I love this printer. Did and re-did the steps above with no resolution.
In addition to "Michael Product Experts" method on page 1, I also did this method:
Don't know which method did the trick, I did the posted method first and this one second, but printer is working now! Thank you
I have had a Canon MX860 for 6 years and absolutely LOVE it. Have had HP's in the past until this one. I got the B200 Error once previously and was able to clear with the suggestion to Open the Cover, let the Printhead go to the left then close the cover and it cleared. About a year later, got the B200 Error again and tried all of the suggestions you will see on this blog ...cleaned the printhead with warm water, installed 2 print tanks that needed replacing, pushing the on/off button several times, pressing the SCAN/COPY/FAX buttons all at once. Nothing worked, so ordered a new printhead from Amazon for around $60 and can now print again. I hope I can use this printer for several more years, but if not, I will probably purchase another Canon.
