INSTALLING UPGRADES
This section explains how to install optional equipment into your
printer. This includes:
> duplex (two - sided printing) unit;
> additional RAM memory.
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.
Ensure printer is switched off at the AC outlet and remove cable from
printer AC input socket.
1. Unpack the new unit and remove any transit material from it.
2. 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.
3. Switch the printer on and wait for it to warm up (about
1 minute).
