Just turning it off doesn't make it forget; the 
info is stored on a chip not in volatile memory, 
otherwise the whole idea of determining ink level 
would work.

There is a procedure, however.  You turn on the 
printer, take the color cartridge out, and turn 
off the printer.  Then turn the printer on and off 
three more times, waiting a few seconds between 
each turn off.  Finally, turn the printer on and 
reinstall the color cartridge.  The printer should 
now recognize the cartridge as a new cartridge and 
begin a calibration check.
