Flash (HP Color LaserJet 4700 Series only) Optional flash is available in various sizes of compact flash cards for storing forms, fonts, and signatures. See Table 8-2 Supplies and accessories on page 563 for specific part numbers. Hard drive accessory (HP Color LaserJet 4700 Series only) The optional hard drive accessory can be mounted in one of the EIO slots on the rear of the formatter. The optional EIO-based hard drive is used for creating multiple original prints (mopies) and storing forms, fonts, and signatures. CPU The HP LaserJet 4700 series formatter incorporates a 533 MHz RISC processor. Printer memory If the printer encounters difficulty managing available memory, a clearable warning message will appear on the control panel. Some printer messages are affected by the auto-continue and clearable warning settings from the CONFIGURE DEVICE menu, under SYSTEM SETUP. If Clearable Warning = Job is set on the control panel, warning messages display on the control panel until the end of the job from which they were generated. If Clearable Warning = On is set, warning messages display on the control panel until is pressed. If an error occurs that prevents printing and Autocontinue = Off is set, the message displays until is pressed. Read-only memory Besides storing microprocessor control programs, the read-only memory (ROM) stores dot patterns of internal character sets (fonts). Random-access memory 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. DIMM slots The DIMM slots can be used to add memory. Flash memory To upgrade printer firmware, upload a new firmware image to the printer. Nonvolatile memory The printer uses nonvolatile memory (NVRAM) to store I/O and information about the print environment configuration. The contents of NVRAM are retained when the printer is turned off or disconnected. ENWW Formatter system 143
