2) If. white areas are produced on prints due to lack
of toner, hold the cartridge horizontal and rock
it 45° slowly back and forth about five times to
distribute toner evenly. (See Fig. 5-8.)
Note:
Be
sure to distribute toner inside the EP cartridge as
instructed. Hold the EP cartridge by the handle and
the rear to distribute toner. Do not hold it by the
main cartridge body (on the handle side). If the
cartridge is not turned in this way, toner may leak
from the EP cartridge.

4)
Do not touch the surface of the drum when
opening the protective shield for the drum on the
bottom of the EP cartridge. If the surface of the
drum becomes dirty, wipe it clean with a piece of
flannel that has been liberally sprinkled with
toner. Do not wipe with a dry cloth and do not
use solvent.
5)
Do not try to
disa~semble
the EP cartridge.
6)
Do not expose a cartridge to unnecessary vibra-
tion or shocks.
7)
An EP cartridge has light-blocking shutters be-
cause the photosensitive drum is sensitive to
strong light. Despite these, however, if the
cartridge is left in strong light for a long time,
white blanks or white stripes will appear on
prints. If this happens, stop the printer at once
and wait a few minutes. This should eliminate
the defective images.
Pay attention to the following points:
*
Clear a paper jam quickly and replace the EP
cartridge in as short a time as possible.
*
When removing the EP cartridge, always place
the cartridge in its storage box and close the
lid. Do not leave it lying in the open after
removing it from the printer.
Note:
Normal room light, measured a few meters from a
window on an average day, is about 1,500 lux. Do
not expose the photosensitive drum to light of this
intensity for more than 5 min.; if the drum is placed
under these conditions accidentally, the EP cartridge
can be stored in a dark place to ''recuperate", al-
though an image may be retained on the drum for
some time. Direct sunlight is 10,000 - 30,000 lux. A
drum exposed to direct sunlight may be ruined.
