CHAPTER 1 MAINTENANCE AND INSPECTION
D. Notes on Cartridge
The cartridge is affected by the environment, regardless of whether it is sealed or
unsealed and installed in the machine or otherwise. Although the properties of the
cartridge change over time independent of how many copies have been made, the
degree of care taken for the cartridge affects how long it may remain stable.
1. Storing Sealed Cartridges
When storing the cartridge in a warehouse or workshop, make sure the place is
controlled to the specifications shown in Table 1-1D.
a. Avoid direct rays of the sun.
b. Avoid areas subjected to appreciable vibration.
c. Do not drop or subject it to impact.
