with your printer.
CAUTION! If you are installing memory
cards sometime after setting up the
printer, turn the printer off and unplug the
power cord before continuing.
Your printer has two memory connectors
for optional memory cards. You can
install any combination of printer
memory and flash memory cards in the
connectors. However, the printer only
recognizes one flash memory card at a
time.
You need a small Phillips screwdriver to
install memory cards.
