Options & Upgrades; Memory - Xerox 8550YDP - Phaser Color Solid Ink Printer User Manual

Options & Upgrades
The Phaser 8400, 8500, and 8550 options and upgrade kits include extra memory, the 525-Sheet
Feeder, the hard drive (Productivity Kit), and configuration upgrades.

Memory

The Phaser 8400, 8500, and 8550 printers each provide two memory slots. Phaser 8500/8550 memory
modules are physically different than Phaser 8400 modules and are
behind the option cover on both models, but a different installation procedure is required as shown below.
Phaser 8400 Memory
Phaser 8400 printers include either 128 or 256 MB of memory, so customers will rarely need to install more
RAM. The benefits of adding memory include the following:
Increased frame buffer size can improve printing throughput for complex jobs
On Phaser 8400N printers with 128 MB of RAM and no hard drive, additional memory increases
the job accounting record capacity from 50 to 500
At least 256 MB of memory is required for automatic two-sided printing
The printer supports PC133-compliant, 128 and 256 MB DIMMs. One or two memory DIMMs may be
installed. The supported memory configurations are 128, 256, 384, and 512 MB (any combination of 128 and
256 MB DIMMs).
Phaser 8500 and 8550 Memory
Phaser 8500/8550 printers support more memory than Phaser 8400 printers (1 GB vs. 512 MB) using 128,
256, and 512 MB memory modules. The printers support combinations of 128, 256, and 512 MB modules
(supported configurations are 256, 384, 512, 640, 768 MB, and 1 GB). Adding memory provides more space
for RAM collation, which is supported by Phaser 8550 models with no hard drive. Larger files will
"chunk-collate" when the printer runs short on memory space. Adding memory improves collation and also
increases the frame buffer size to improve printing throughput for complex jobs.
