1-2 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 aff[...]

CHAPTER 1 MAINTENANCE AND INSPECTION 1-3 2. Storing and Handling Unsealed Cartridges The photosensitive medium is an organic photoconductor (OPC), which is extremely susceptible to light. Since the cartridge also contains toner , you must be extra careful when storing or handling the cartridge. Make sure the user is aware of this fact and will hand[...]

Figure 1-2D 3) Do not force open the shutter for the photosensitive drum cover found at the bottom of the cartridge; do not touch the surface of the photosensitive drum. If the surface of the photosensitive drum has become soiled, wipe it using a flannel cloth coated with toner . Do not dry wipe it or use solvent. 4) Do not disassemble the cartridg[...]
