MEMORY EXPANSION
The machine has a base Dynamic Random Access Memory (DRAM) of 8
megabytes (MB). You can upgrade memory by inserting additional memory
modules in the two available Single Line Memory Module (SIMM) sockets.
Note: The machine has an additional socket that accepts only a PostScript
®
ROM Dual Line Memory Module (DIMM). Install the PostScript
®
ROM
DIMM module when you want to use the PostScript
®
option.
☛ Refer to the “Installing DRAM SIMM Modules”.
☛ Refer to this chapter for instructions on how to install the PostScript
ROM DIMM module.
The DRAM SIMM sockets accept modules of 4 MB, 8 MB, 16 MB, or 32 MB. You
can add a total of 64 MB of DRAM, for a total of 68 MB.
You should install additional DRAM when you print high-resolution graphics or
large documents on a regular basis, or use memory-intensive features such as
special fonts or duplex printing. Adding memory increases printing speed.
Extra memory is required for some features such as duplex print jobs on large
paper sizes. Table 4-2, 4-3 list the amount of memory required for duplex printing
on large paper sizes.
