CHAPTER 1
When the cartridge is removed from the printer, place it in the protection bag or wrap it with
a thick cloth to avoid exposing it to light.
3) Keep the cartridge away from computer CRT displays, disk drives, and floppy disks. The
magnet in the cartridge can corrupt the data in the memory of your computer or the data on
disks.
4) Do not expose the cartridge to sunlight or strong light, since it is sensitive to light.
Otherwise, it may result in image defects. In such a case, stop using the printer for a while
and print quality should recover except when the cartridge is exposed to light for a long time.
5) Do not open the photosensitive drum protective shutter on the cartridge with hands. Do not
touch or clean surface of the photosensitive drum.
6) Do not stand the cartridge on end or turn it upside down. Labeled side of the cartridge
should be facing up always.
7) Carry the cartridge grasping both handles on each end to avoid dropping the cartridge.
