5. Points to keep in Mind about
Cartridges
a. Photosensitive Drum Cartridges
• Be sure to wrap the photosensitive
drum cartridges with a protective
cover whenever it is taken out of the
copier. If it must be left out of the copi-
er for a long time, be sure to put it in a
protective bag.
• Work fast as when cleaning. Exposing
the drum to light for a long time will
affect print images.
• As a rule, do not touch or clean the
drum. If absolutely necessary, use a
flannel cloth.
• Do not use lint-free paper. It will dam-
age the surface of the drum. Further,
never use solvent.
