Putting paper in the lower tray unit
After you have installed the lower paper tray,
you can put paper in it the same way you put
paper in the upper paper tray.
SO-DIMM (Memory)
The memory board is installed on the main
controller board inside the machine. When
you add the optional memory board, it
increases the performance for both copy and
print operations.
The machine has 64 MB of standard memory
and a slot for optional additional memory. The
memory can be expanded up to a total of 576
MB by installing a commercially available
SO-DIMM (Dual In-line Memory Module).
The machine uses memory modules that are:
144 pins, no-parity, SDRAM with 64 MB or
more.
The machine is not compatible with Extended
Data Output (EDO) DIMM.
The following SO-DIMM sizes can be
installed:
■
64 MB TechWorks 12345-0001
■ 128 MB TechWorks 12462-0001
■
256 MB TechWorks 12485-0001
■
512 MB TechWorks 12475-0001
