Help.  

I get an error message:  "An ink cannot be recognized.  Open the printer's cover and replace the ink on which the ink lamp is off.

Trouble is....they are all lit.  I've taken them all out and put them back in a few times to no avail.  I have no idea which one it doesn't recognize.

Try contacting Debbie at icingimages and she may be able to help you.  She's very good with canon printers and will help even if you didn't buy from her, however I highly recommend her gold label inks and premium icing sheets.
