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.
