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
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 copier
and printer operations, and lets you store
more fax messages.
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 Buffalo Technology VN133-64M
■
128 MB Buffalo Technology VN133-128M
■
256 MB Buffalo Technology VN133-256M
■
512 MB Buffalo Technology VN133-512M
In general, SO-DIMM must have the following
specifications:
Type: 144 pin and 64 bit output
CAS latency: 2 or 3
Clock frequency: 100 MHz or more
Capacity: 64 MB to 512 MB
DRAM type: SDRAM
Improper Setup
Do not put transparencies, labels or
envelopes in the paper tray of the optional
lower tray unit. This might cause paper
jams.
