PIXMA MX922 error code B200 workaround, thanks to Canon Community Bulletin Board!

Don't replace the print head!  This happened eventually on both the MX922's we have

1. Turn OFF Power
2. Open the print head bay (as though you were about to change inks)
3. Turn ON power
4. Wait for print carriage to start moving to the left and let it go past half way
5. Before print carriage reaches left hand side (but after going halfway across) shut the cover.
6. Leave the Printer turned on
7. Good to go.
I tried this and it worked for me
