The whopping onboard memory of 128MB is more than enough to handle most complicated documents such as large raster images, complex vector images from software such as Adobe Illustrator. Huge PDF files tend to be a big culprit with holding up printer spoolers, but they are not an issue with this beast. In fact, the printer’s RAM helps it to buffer large amounts of documents at once, so that there is little chance of a logjam during network printing. If you happen to be running a small country, you can upgrade the printer’s RAM to 384 megs.
