Embedded print server For all models except the HP LaserJet 4014 base model, the product includes an HP Jetdirect embedded print server for connecting to a 10/100Base-TX network. Hard-disk The hard-disk is mounted on the formatter cage door. The hard disk is used for creating multiple original prints (mopies) and storing forms, fonts, and signatures. NOTE: All models have a solid state module (SSM) installed except the HP LaserJet Enterprise 600 M603xh. CPU The product formatter incorporates a 800 MHz RISC processor. Memory If the product encounters a problem when managing available memory, a clearable warning message appears on the control panel. Random-access memory The formatter has one DIMM slot. All models come with 512MB of memory installed. Additional memory can be added up to a maximum of 1GB. The random-access memory (RAM) contains the page, 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. Memory capacity can be increased by adding DIMMs to the formatter. Note that adding memory (DIMMs) might also increase the print speed for complex graphics. Nonvolatile memory The product uses nonvolatile memory (NVRAM) to store I/O and information about the print environment configuration. The contents of NVRAM are retained when the product is turned off or disconnected. DIMM slot The DIMM slot can be used to add product memory. ENWW Formatter system 9
