UPLEX
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).
