CHAPTER 10 MAINTENANCE AND SERVICING IV. STORING AND HANDLING THE CARTRIDGE The cartridge is subject to the effects of the environment whether its packing seal is intact or removed or whether it is inside the machine or otherwise, changing over time regardless of the number of copies made. The degree of change is highly dependent on the site of installation and how it is maintained, and no general rule may be drawn; however, it is important to exercise care when storing or handling it.
