CAUTION
Exposing the drum to light shortens its life. Do not expose the
drum to direct sunlight, and install it within five minutes under
typical room lighting conditions. When removing the drum
from its packaging, do not touch the surface of the drum.
Fingerprints and scratches can damage the surface and cause
poor print quality.
3. Using both hands, slowly slide the drum onto the drum auxiliary
rod. When the drum reaches the area where the auxiliary rod
connects to the drum shaft, lift the drum very gently over the
connection. Let the drum rest on the rubber rollers as you
gently guide it into the printer.
CAUTION
The drum must rest on the rubber rollers to avoid being
scratched.
4. When the drum is fully inserted into the printer, the end of the
drum is slightly recessed relative to the front of the printer and
the rubber guide rollers should be visible. Slightly lift the dru m
up off of the rubber rollers and rotate the drum by hand while
applying inward pressure, until the drum moves slightly farther
into the printer and locks in place.
CAUTION
In order to position the drum slot and the drum shaft pin, push
the drum in all the way to the back and rotate it until you feel it
drop in place. Failure to lock the drum in place properly can
severely damage the printer.
Never force the drum onto the shaft. If it feels as thoug h the dr um is
not seating properly, remove the drum and inspect the shaft for
foreign material or burrs.
5. Remove the drum auxiliary rod from the drum shaft.
6. Install the nut on the drum shaft and tighten it securely by hand.
7. Install the drum plate and tighten the thumbscrews. While
installing the drum plate, hold the copper grounding clip with
your thumb. Otherwise the grounding clip can be bent, making
no contact with the drum shaft.
