Why does laser toner have an expiry date? My laser toner cartridge finally ran "dry" after 8 years of use (same cartridge) and the replacement refill that I purchased has an expiry date which is listed as a little over year from now. I also believe that most new cartridges also have an expiry date but since mine lasted for so long, I don't understand the purpose of having an expiry date.
