Title: Age is important!
Review: I find that the quality of toner deteriorates as a function of both time and storage conditions. I do not know what storage conditions promote deterioration. My personal experience is that the older the cartridge, the more I have to increase the contrast in the printer settings. My guidelines are to avoid toner older than 5 years old. I determine the age by requesting the copyright on the lower left hand corner of the back long side of the box. I strongly encourage readers to respond to their agreement or disagreement with this assessment.
