In general, more memory improves throughput, provides more storage for
downloadable fonts, and allows printing of the most complex images.
Additional memory can also reduce offload time by increasing the size of
input buffers for the I/O ports. Adding a 16-Mbyte SIMM to a Phaser 540
provides the following specific benefits:

provides the following specific benefits:
■
Larger I/O buffers (increases from 256 Kbytes to 1 Mbyte)
■
Improved imaging performance
■
Improved network performance
