3.Lift each of the image drum units out of the printer and 
place them in a safe place away from direct sources of 
heat and light.
4.Locate the two fasteners (5) at each side of the belt and 
the lifting bar (6) at the front end.
5.Turn the two fasteners 90° to the left. This will release the 
belt from the printer chassis.
6.Pull the lifting bar (6) upwards so that belt tilts up towards 
the front, and withdraw the belt unit from the printer.
CAUTION!
The green image drum surface at the base of each 
cartridge is very delicate and light sensitive. Do not 
touch it and do not expose it to normal room light for 
more than 5 minutes. If the drum unit needs to be out of 
the printer for longer than this, please wrap the 
cartridge inside a black plastic bag to keep it away from 
light. Never expose the drum to direct sunlight or very 
bright room lighting.

drum units.

10 minutes before opening the cover.

fully.
2.Identify the fuser handle (1) on the top of the fuser unit.
3.Pull the fuser retaining lever (2) towards the front of the 
printer so that it is 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.

INSTALLING UPGRADES
This section explains how to install optional equipment into your 
printer. This includes:
>duplex (two-sided printing) unit;
>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).

ADJUSTING WINDOWS PRINTER DRIVERS
Once your new upgrade has been installed, you may need to 
update the Windows printer driver so that the additional features 
are available to your Windows applications.
Remember that if your printer is shared between users on 
different computers, the driver must be adjusted on each user’s 
machine.
The illustrations shown here are for Windows XP. Other Windows 
versions may appear slightly different, but the principles are the 
same.
If you have installed a memory upgrade it is not necessary to 
change the printer driver, and you can ignore this section.
If you have installed a duplex unit, proceed as follows:
1.Open the Printers window 
(called “Printers and Faxes” in 
Windows XP) via the Start Menu 
or from the Windows Control 
Panel.
2.Right-click the printer icon for 
this printer, and choose 
Properties from the pop-up 
menu.
3.On the Device Options tab, 
check the box for the upgrade 
you have just installed.
4.Click OK to close the properties window, and then close 
the Printers window.

							Clearing paper jams> 100
CLEARING PAPER JAMS
Provided that you follow the recommendations in this guide on 
the use of print media, and you keep the media in good condition 
prior to use, your printer should give years of reliable service. 
However, paper jams occasionally do occur, and this section 
explains how to clear them quickly and simply.
Jams can occur due to paper misfeeding from a paper tray or at 
any point on the paper path through the printer. When a jam 
occurs, the printer immediately stops, and the Alert LED on the 
Status Panel (together with the Status Monitor) informs you of 
the event. If printing multiple pages (or copies), do not assume 
that, having cleared an obvious sheet, others will not also be 
stopped somewhere along the path. These must also be removed 
in order to clear the jam fully and restore normal operation.
