Manage memory
This MFP supports up to 544 MB of memory: 512 MB DDR plus 32 MB of additional memory on the
formatter board. You can add additional memory by installing dual data-rate (DDR) memory. To allow
for memory expansion, the MFP has two DDR slots, which accept 128 or 256 MB of RAM each. For
information about installing memory, see
Install memory and print server cards .
The MFP features Memory Enhancement Technology (MEt), which automatically compresses page
data to provide the most efficient use of the MFP’s RAM.
The MFP uses DDR SODIMM. Extended data output (EDO) DIMMs are not supported.
NOTE If memory problems occur when you are printing complex graphics, you can make more
memory available by removing downloaded fonts, style sheets, and macros from MFP memory.
Reducing the complexity of a print job from within a software program can help avoid memory
problems.
