Appendix C: Adding memory to your printer
You can print more complex documents and download more fonts to your printer if
you add RAM. To do this you have to open up the printer and insert a SIMM (Single
Inline Memory Module). The printer can hold up to 64 MB of RAM, in two SIMM
sockets. There is already at least one SIMM installed in the printer.
When you have installed the memory you must update the drivers in every Windows
or Macintosh computer that uses the printer.
Specifications
You can add SIMMs of any size from 2 MB to 32 MB. SIMMs must be non-parity 72-
pin, 70 nanoseconds or faster, non-composite, symmetrical, low-profile, 5-volt, and
tin leaded. This kind of memory is readily available from many sources, or you can
order upgrade kits direct from GCC. Use only EDO (extended data out) or FPM (fast
page mode). You cannot use DIMMs, SDRAM, or other special RAM technologies.
SIMMs do not have to be installed in pairs, nor do you have to add a SIMM of the
same size as that already installed. You can install any capacity SIMM in either
socket.
Why would I need to add memory to the Elite XL 20ppm?
You can print virtually any 600 dpi pages with 16 MB of RAM and virtually any 1200
dpi pages with 32 MB (if your model of the Elite XL 20ppm supports this resolution).
You can use up RAM by setting the printer to Auto Switch between PostScript and
PCL 5. Utilities like NEST, WebAdmin, and TCP/IP use small amounts of RAM;
together with Auto Switch, these require under 4 MB.
In addition, you will need printer RAM for any fonts you download. These require as
much RAM as the space they occupy on the hard drive of your computer. In general,
fonts occupy under 50K of RAM.
With an extra 8 MB of RAM or more, you will see minor performance improve-
ments.
Required tools and safety precautions
You should not need any tools to add memory to your printer. However, you should
guard against static charges. Your body can easily accumulate a static charge; if you
touch a sensitive piece of circuitry, you can destroy it without realizing.
