increase the printer's memory up to 1,280 MB by plugging in the optional
memory modules.

You can select additional memory modules from 128, 256, 512 or

Precautions for Handling the Printer's Main Controller Board
and Memory Modules
To protect electronic parts, discharge static electricity from your body by
touching a water pipe (faucet) or other large metal object before handling
the memory modules. Or, wear an antistatic wrist strap, if possible, when
you install the memory modules.
Always hold the main controller board or a memory module by its edges
as shown below to avoid damaging electronic parts.
