Single in-line memory modules (or SIMMs) are compact circuit
boards with surface-mount memory chips. The QMS 2425/2425
TURBO Print System base model comes standard with one 8 MB
SIMM, for a total of 8 MB of RAM; the 2425 EX comes with one 16
MB and one 8 MB SIMM, for a total of 24 MB of RAM; and the 2425
TURBO EX comes with two 16 MB SIMMS, for a total of 32 MB of
RAM. However, you can add SIMMS up to a total of 128 MB of RAM.
Additional printer memory allows you to download more fonts and
increase the printer's buffer (area where data sent from the computer
is stored while it’s waiting to be printed).

▲ Caution: This hardware change automatically restores defaults. If
your memory settings are specific for your environment, print an
advanced status page before making this hardware change, so you
can recover these memory settings.
It's very important to protect the printer controller board from
electrostatic damage while performing this SIMM installation. Please
review the anti-static caution in “Removing the Controller Board” on
page 2-2.
