Handling the Cartridge
When setting the cartridge to the copier
or if the toner starts to run short, hold the
cartridge horizontally as shown in Figure
6-1, and rotate it in both directions about
90° to even out the toner inside it. Do
not shake the cartridge or hold it in a dif-
ferent way; otherwise, toner may leak
out the cartridge.
Figure 6-1
Do not place the cartridge upright or
upside down; do not shake it.
Figure 6-2
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.
MAINTENANCE AND SERVICING ®
if the surface of the photosensitive drum
has become soiled, wipe it using a flan-
nel cloth coated with toner. Do not dry
wipe it or use solvent.
Do not disassemble the cartridge.
Do not subject the cartridge to vibration
or impact; in particular, do not force
down the photosensitive drum from
above the shutter for the drum cover.
Keep the cartridge out of reach of chil-
dren.
The photosensitive drum is susceptible
to light and, therefore, equipped with a
light-blocking shutter; nevertheless,
exposure to light for a long time can
affect the drum, resulting in copies with
white spots or vertical lines. Leave the
copier alone for some time for possible
recovery; to avoid residual memory,
which results in white spots or vertical
lines, however, keep the following in
mind.
Work quickly when. removing, jams. or
replacing cartridges.
When the cartridge must be removed
for work, be sure to put the cartridge in
its storage box or cover it;.do not leave
it without protective measures once it is
outside the copier.

The drum would recover to more or less
its normal condition if left alone for five
minutes in a dark place after exposure to
an intensity of 1500 lux (about 5 minutes
under general lighting). However, you
must try to avoid any exposure. (The
rays of the sun have intensities ranging
between about 10000 and 30000 Iux.)
