140 Maintenance Chapter 5
Handling Guidelines
• Do not expose the cartridge to direct sunlight. Do not
expose it to bright light or to room light for more than
5 minutes.
• Do not open the drum’s protective shutter on the
cartridge. If the shutter is open and the drum is
damaged, print quality might deteriorate.
• Do not stand the cartridge on end, and do not turn it
upside down. If the toner becomes caked in the
cartridge, it might prove impossible to free it even by
shaking the cartridge, which results in print quality
deterioration.
•Keep the cartridge away from a monitor's cathode ray
tube (CRT), disk drives and floppy disks. The magnet
in the cartridge can distort the image on the CRT, or
damage data on disks.
• Do not touch the drum’s protective shutter. Avoid
holding the cartridge in such a way that your hand is
touching the drum’s protective shutter.
• When transporting the printer, remove the cartridge
from the printer. (Put the cartridge in its original
protective bag or wrap it with thick cloth to prevent
exposure to light.)
