Cartridge
This section describes procedures for handling, storing and replacing the
drum cartridge.
8.2.1 Drum Cartridge Handling Precautions
The drum cartridge consists of a light-sensitive drum, a developer and a
transfer roller. The drum cartridge is capable of printing about 30,000 A4
pages (continuous portrait, at the default print density, with 5% color cover-
age) with a 1:1 color/monochrome ratio, and when printing in units of four
pages.
Printing in units of one page or two pages results in about 24,000
pages of life span. Printing in units of three pages results in about
28,000 pages.
Handling Precautions
• Make sure nothing touches or scratches the light-sensitive drum surface
(green colored part) or transfer roller (black colored part). Scratches, dirt,
or oil from your hands on the drum or transfer roller deteriorates print
quality.
• Do not expose the drum cartridge to direct sunlight and avoid exposing
the drum cartridge to fluorescent indoor light, as this may result in drop-
outs or dirty printing.
• When replacing the drum cartridge, work on a desk or other flat surface
to avoid scratching the light-sensitive drum and transfer roller.
• Avoid removing the drum cartridge from the printer before it is time to
replace it. Removing and replacing the drum cartridge can cause dirt to
stick to the cartridge and deteriorate print quality.
• Avoid tilting or shaking the drum cartridge when removing it, as toner
may spill inside the printer and cause damage.
• To ensure good print quality, keep the drum cartridge level when handling
it.
• The drum cartridge weighs 4.5 kg. Handle it carefully.
• Wrap used drum cartridges in a plastic bag and dispose of them as non-
burnable waste.
Storage Precautions
• Do not unpack the new drum cartridge until you are ready to install it. If
the drum cartridge is unpacked put it in its aluminum package for storage.
• Store drum cartridges away from direct sunlight under the following con-
ditions:
Ambient temperature range, 0 to 35°C; humidity range, 15 to 80 % RH
(no condensation)
• Avoid storing in hot humid areas.
• Avoid storing near magnetic objects such as CRT screens, disk drives, or
floppy disks.
• Keep out of reach of children.
• Store in a level position.
