[QUOTE]\nAs I stated, I wasn't there, so I'm guessing. I'm assuming the incident \nwas accurately reported, and I can't think of a good reason for a \ncartridge with a head built in would have a expiration date that would \nshut down the printer.[/QUOTE]\n\nA good reason? From the manufacturers point of view, refilling is a very\nbad thing to do. Most of the profit comes from those cartridges, not from\nthe printer price. Anything you can do to prevent refilling increases the\nbottom line.
