Replacing The Photoreceptor Drum
67
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,
because fingerprints and scratches can damage the surface
and cause poor print quality.
19. Using both hands, carefully 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
slightly 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.
20. When the drum is fully inserted into the printer, the end of the
drum will be slightly recessed relative to the front of the printer
and the rubber guide rollers should be visible. Slightly lift the
drum 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 may
cause severe damage to the printer.
Never force the drum onto the shaft. If it feels as though the
drum is not seating properly, remove the drum and inspect the
shaft for any foreign material or burrs.
21. Remove the drum auxiliary rod from the drum shaft.
22. Install the nut and tighten it securely by hand on the drum shaft.
