Chapter 3 Consumable Replacement
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 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 can severely damage 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 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.
