Optional Memory
By adding 32 MB of optional memory, the amount of
memory available for Bitmapping will be increased and
you will thus be able to transmit and receive
documents using the Ultra fine resolution mode.
In addition, you will be able to store a greater number
of documents into memory (for transmission or through
reception).
