VII. NOTES TO THE SERVICE PERSON
A. Storing the Drum Cartridge and the Toner Cartridges
Regardless of whether they have been opened or not, the cartridges (Y, M, and C
toner cartridges, black toner cartridge, and drum cartridge) remain subject to the influ-
ences of the environment, and their characteristics change over time. (This is also true
regardless of how many copies/prints they have processed.)
The speed of change, however, is dependent on the conditions of the site and main-
tenance and, therefore, it is important to take full care when storing or handling them. (Be
sure to instruct the user to be careful when storing and handling the toner cartridges.)
1. Before Opening the Package
When storing the cartridges (Y, M, and C toner cartridges, black toner cartridge, and
drum cartridge) in a storeroom or a workshop, be sure that the place complies with the
conditions in Table 1-601; in addition,
1) Avoid direct sunshine;
2) Avoid an area subject to appreciable vibration; and
3) Avoid subjecting them to impact by hitting or dropping.
