I have a Canon Pixma MP210. So, I always print in black & white b/c I just print out documents. I've had an old, empty color ink cartridge sitting in there, though. Today I took the empty black cartridge out to recycle at Staples, as I was going to buy a new one. I got the bright idea to also take out the empty color cartridge, so that I could get that recycling credit, too. Well, now it will not print without a color cartridge, even an empty one, installed. It says: "The following ink cartridge cannot be recognized. Printing cannot be executed b/c the ink cartridge may not be propertly installed, blah blah blah." Is there any way to bypass this??? I don't want to have to buy a new color cartridge, as I won't even use it! Help, please.
