Handling Suggestions
1.
When institing a cartridge, slowly rock it 45 degrees about its long axis (see Figure 2-2) about
five times to distribute the toner evetiy.
2. As shown in Figure 2-2, do not stand the cartridge upright invert i~ or handle it rougMy.
3.
Do not touch the surface of the drum when opening its protective shield on the bottom of the
EP-S Cartridge. If it becomes absolutely necessary to cl-n the drum, use only toner app~ed
with a dry cloth. Do not wipe with a d~ cloth and do not me any solvents.
4. Do not attempt to disassemble or refill the EP-S Cartridge.
5. Do not expose a tidge to unnecessary vibration or mechanid shock.
6. Nthough an EP-S Cartridge has fight-blocking shutters to protect the photosensitive drum,
exposure to light for a long period of time may muse fight Orwhite arias to appear on prints. If
this
happens, stop the printer and wait a few minutes. This shotid efiminate the problem. In
extreme cases, some life may be restored to the drum by placing the EP-S Cartridge in a dark
place for an extended period of time. If drum exposure has been excessive, the EP-S Cartridge
may require replacement.
7. If it becomes necessary to rotite the drum, always turn it in the same direction it turns while
making prints. If it is turned backward, the spring-loaded contact that appfies the developing
bias to the inside rim of the developing cytinder may be bent backward so that it no longer
contacts the cylinder, thus preventing proper image development.
Note
Normal room light measured a few meters from a window on an average day, is
1
about 1,500 lUX. Do not expose the photosensitive drum to tight of this intensi~
TV
for more than five minutes. H accidentiy exposed under these conditions, the
EP-S Cartridge can be stored in a dark place to recuperate, although an image
may be retained on the drum for some time. Direct sutight is 10,000-30,000 lUX.
A dmm exposed to light of this intensi~ may be permanently damaged.
