    FUSER REPLACEMENT
    The fuser is located inside the printer just behind the four image 
    drum units.
    Switch off the printer and allow the fuser to cool for about 
    10 minutes before opening the cover.
    1.Press the cover release and open the printer’s top cover 
    fully.
    2.Identify the fuser handle (1) on the top of the fuser unit.
    3.Pull the two fuser retaining levers (2) towards the front of 
    the printer so that they are fully upright.
    4.Holding the fuser by its handle (1), lift the fuser straight 
    up and out of the printer. If the fuser is still warm, place it 
    on a flat surface which will not be damaged by heat.
    WARNING!
    If the printer has recently been powered on, some fuser 
    components will be very hot. Handle the fuser with 
    extreme care, holding it only by its handle, which will 
    only be mildly warm to the touch. A warning label clearly 
    indicates the area. If in doubt, switch the printer off and 
    wait at least 10 minutes for the fuser to cool before 
    opening the printer cover.

    into their slots in the metal partition which separates the 
    fuser area from the image drums.
    8.Push the two retaining levers (2) towards the rear of the 
    printer to lock the fuser in place.

    INSTALLING UPGRADES
    This section explains how to install optional equipment into your 
    printer. This includes:
    >duplex (two-sided printing) unit;
    >additional RAM memory;
    >additional paper tray
    >cabinet
    DUPLEX UNIT
    The duplex unit adds the function of two-sided printing, using 
    less paper and making large documents easier to handle. It also 
    enables booklet printing, which uses even less paper and makes 
    large documents even easier to handle.
    The duplex unit slides straight into the rear of the printer and 
    requires no tools to install.
    1.Unpack the new unit and remove any transit material from 
    it.
    2.Switch the printer off. It is not necessary to disconnect the 
    AC power cable.
    3.Ensure that the unit is the right way up, as shown, and 
    push it into the slot behind the rear panel. The panel will 
    swing inwards as you push the unit into it. Push the unit 
    all the way in until it stops and latches home.
    4.Switch the printer on and wait for it to warm up (about 
    1 minute).
