Random Access Memory (RAM) The RAM contains the page and I/O buffers and the font storage area. It stores printing and font information received from the host system, and can also serve to temporarily store a full page of print image data before the data is sent to the print engine (see “Page Protect” below). RAM memory capacities for each printer are shown in “Printer Features” on page 1-2. Memory capacity can be increased by adding DIMMs to the Formatter PCA. Note that adding memory (DIMMs) may also increase the print speed of complex graphics. DIMM Slots The DIMM slots may be used to add memory, fonts, or firmware upgrades. Note that DIMMs and SIMMS are not compatible.
Non-Volatile Memory (NVRAM) The printer uses NVRAM to store I/O and information on the print environment’s configuration. The contents of NVRAM are retained when the printer is turned off or disconnected. Memory Enhancement technology (MEt) The Hewlett-Packard Memory Enhancement technology (MEt) effectively doubles the standard memory through a variety of font and data compression methods. Note MEt is only available in PCL mode; it is not functional when printing in PS mode. Formatter System 5-19
