Section 1 - Introduction to 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.
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. Do not use gold plated connectors. 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 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.
You will reduce available RAM by setting the printer to Auto Switch between PostScript and PCL
5. Options like TCP/IP, WebAdmin, and NEST use additional RAM; together with Auto Switch,
these utilize approximately 4MB of the available RAM, thereby reducing the RAM freely
available for print jobs..
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 minor performance improvements as you add additional memory up
to a maximum of 64 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.

Section 2 - Installing RAM into the Elite 12 Series Printer
1. Switch off the printer.
2. Unplug the interface cables from the back of
the printer. Do not unplug the power cord from
the AC outlet.
3. If necessary, move the printer so that you have
clear access to its left side.
4. Remove the paper tray.
5. Open the top cover by pressing the release
button on the top right of the printer.
6. Remove the side cover. Unscrew the two
thumbscrews at the rear of the printer (A). If
these are tight, you may need to use a #2
Phillips screwdriver.
7. Reach inside the case. Pull the edge of the
cover (B) toward you, then move the cover
away from the rest of the printer to prevent it
from latching again.

8. Place both hands on the top of the side cover
(C). Lift the edge of the cover next to the top
cover; this unlatches the cover and you should
be able to slide the cover away from the printer.
9. IMPORTANT: Attach a grounding wrist strap to
the perforated metal chassis, or touch the
chassis regularly to dissipate static
electricity from your body.

10. The ROM and RAM cards are at the right of the
controller board. Remove the ROM card to get
better access to the RAM slots.
Note: Your controller board may vary from the
one shown. Some Elite 12 models ship without
a physical ROM card in place.
If your printer has a ROM card in the slot to the
left, remove it as follows:
a. Place your index fingers under the back
edge of the ROM card.
b. Using your thumbs, slowly push the two
retaining clips outward until the clips clear
the top surface of the ROM card.
c. Pivot the ROM card away from the
retaining clips and remove the ROM card
from the socket.
d. The ROM card has a notch in it; this must
be at the top of the contacts when you
reinstall it.
e. Put the ROM card in a safe place; after
you have installed the RAM you will need
to reinstall it.

11. Install the RAM SIMM.
a. Position the SIMM so that the notch is
toward the top.
b. Place the SIMM in the socket so that the
top of the SIMM is angled toward your left.
Gently press the SIMM down into the
socket.
c. Pivot the SIMM so that it moves upright.
The retaining clips will snap into place. If
the retaining clips will not snap into place,
you have not inserted the SIMM correctly.
12. Reinsert the ROM card (if necessary) in the
same way that you inserted the SIMM.
Warning: If the RAM SIMM and ROM card
are not correctly inserted completely into
the socket, your printer may display an
error message when you turn it on and it
will not operate.
13. If you are having trouble inserting the SIMM or
ROM card:
• Make sure that the cards are in the correct
sockets. The ROM card is slightly shorter
than the RAM SIMM.
• Make sure that the notch in each card is
toward the top.

14. Remove the grounding wrist strap from the
printer (if necessary), and reinstall the printer’s
side cover. Don’t tighten the thumbscrews. Turn
on the printer and wait to see if the control
panel shows the “Ready”message. If it does,
turn the printer off and go on to the next step.
•If the “Ready”message doesn’t appear,
turn off the printer and remove the cover.
Gently try to rock the ROM card and
SIMMs. If they are inserted correctly, they
should not move. Carry out steps 11, 12
and 13 again, replace the cover and turn
the printer on.
•If the “Ready”message still doesn’t appear,
and you are confident that you have
installed the ROM card and SIMM correctly,
contact GCC Technical Support at
781.276.8620 (U.S. only; outside the U.S.
see back cover), www.gcctech.com, or your
authorized GCC dealer.
15. If the printer is ready, tighten the thumbscrews
(at the rear of the side cover)
by hand. Make certain that the printer is
switched off. Reinstall the interface cables
(if necessary, insert the parallel port plug first).
16. Turn the printer on again. If the “Ready”
message shows in the control panel, the
physical installation succeeded. Now confirm
the installation and update the printer driver on
all computers that use this printer. See Section
4 of this guide.

Section 3 - Installing RAM into the Elite XL 20 Series Printer
1. Switch off the printer.
2. Unplug the interface cables from the back of
the printer. Do not unplug the power cord from
the AC outlet.
3. If necessary, move the printer so that you have
clear access to its left side.
4. Remove the side cover. Unscrew the two
thumbscrews at the rear of the printer, as
shown. If these are tight, you may need to use
a #2 Phillips screwdriver.
5. Slide the left cover assembly towards the rear
of the printer. Swing out the bottom edge first
and then lower the left cover out of the guide
channel.
