Installing a Memory Card
NOTE: If you are adding an optional duplex module after setting up the printer, be sure to turn off the printer, unplug
the power cable, and disconnect all the cables from the back of the printer before completing these tasks.
NOTE: The 64 MB memory card comes with the optional duplex module. Before you use the optional duplex module,
you need to install the 64 MB memory card on the printer. If you already have an existing memory card installed on the
printer, you do not have to use the 64 MB memory card provided with your duplex module.
The optional duplex module attaches to the back side of the printer.
