The Memory Expansion Board
You probably need to add memory if you have trouble printing
complex or graphics-intensive pages, or if any of the following
messages appear often: INSUFF MEMORY, PAGE BUFFER FULL, or
ADD MEMORY. Using the INDIVIDUAL setting in the CH mode in
SelecType also requires additional memory.
To add memory, you need the optional OK memory board and
enough memory chip sets to equal the amount of memory that you
want to add. There are two types of chips you can buy for the
memory expansion board:
256Kbit x 4 80 ns DRAM 20-pin DIP (Four of these constitute a
0.5MB chip set.)
1Mbit x 4 80 ns DRAM 20-pin DIP (Four of these constitute a
2.0MB chip set.)
The printer’s built-in memory is 0.5MB. By installing the RAM chips
as described in this section you can increase the printer’s memory up
to 5.5MB.
Note:
The optional Epson GL identity (ID) card requires a minimum
of 1MB additional memory. If you use another ID card,
consult its manual for memory requirements.
Although the memory board can hold up to 8.0MB of RAM
chips, the printer can access only 5.0MB of additional
memory.
Memory chips can be purchased from Epson Accessories.
First you install the RAM chips on the memory board. Then you
install the memory board in the printer. If you have questions about
this process, see your dealer or a qualified service person.
