INSTALLING UPGRADES
This section explains how to install optional equipment into your 
printer. This includes:
>
duplex (two sided printing) unit;
>
additional RAM memory;
>
10GB hard disk drive.
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.
NOTE
The duplex unit requires an additional 64MB memory upgrade.
