Dual In-Line Memory Module (DIMM)
"
You may need additional memory (DIMM) for complex graphics and 
for duplex printing. 
A dual in-line memory module (or DIMM) is a compact circuit board with 
surface-mount memory chips.
Your printer comes with 128 MB SDRAM printer memory on board. However, 
you can upgrade to a maximum of 640 MB of RAM through the installation of 
an additional unbuffered SDRAM DIMM. Your printer comes with one free 
DIMM slot.
Installing a DIMM
CAUTION
It’s very important to protect the printer controller board and any associated 
circuit boards from electrostatic damage. Before performing this procedure, 
review the antistatic caution on Page 136. In addition, always handle circuit 
boards by the edges only.
Turn off the printer and disconnect the power cord and interface cables.

If the duplex unit is installed, remove it.
