Your printer comes with at least 32MB already
installed. (Some printer models may have more
standard memory.) You can purchase many differ-
ent memory options from Lexmark for the three
memory connectors in your printer. The maxi-
mum amount of usable memory is 384MB. Use
SDRAM DIMM memory cards that meet the fol-
lowing criteria:
• 100MHz or greater
• 100 pin
• 4K refresh rate
• Unbuffered, non ECC
• x32
• 3.3 V
If you need to remove a memory card, refer to the
Lexmark C720 online information.
To install optional memory:
1
Complete the steps in "Removing the
system board" on page 23 if the system
board is still installed.
2
Locate the memory connectors on the sys-
tem board.
Each connector can support either a printer
memory card or a flash memory card.
You cannot operate the printer with more
than one flash memory card installed.
