Step 10e. Installing Additional Memory
Introduction
You can print more 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 DIMM (Dual Inline Memory Module). The printer ships
with 64MB of RAM, located on the controller board. There is one DIMM slot in the printer.
Specifications
You can add SDRAM DIMMs of 64, 128 or 256MB, for a maximum of 320MB total (256MB DIMM plus
64MB onboard). The printer uses standard 168-pin, PC133 SDRAM DIMMs. These can be obtained
through GCC, or through most major computer suppliers.
Why would I need to add memory to the printer?
GCC printers ship with enough standard RAM to handle most print jobs at the largest page size and
resolution supported by the printer. Some print jobs, however, may be more complex than the standard
RAM is able to handle and therefore require additional RAM. Jobs with heavy graphical content and/or
many font faces will typically require the most memory.
In addition, you’ll 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, each font occupies 50 -100k of
RAM.
You will continue to obtain performance improvements as you add additional memory up to a
maximum of 320 MB of RAM.
Required tools and safety precautions
You should not need any tools to add memory to your printer. However, you should guard against
static discharges. Your body can easily accumulate a static charge; if you touch a sensitive piece of
circuitry, you can destroy it without realizing.
GCC strongly recommends that you use a grounding wrist strap. You can buy one from any computer
parts outlet. If you do not have a grounding wrist strap, touch the perforated metal chassis of the
printer to discharge any static electric charge your body may have.
