Note Printer Memory If the printer encounters difficulty managing available memory, a clearable warning message will be displayed on the Control Panel. Some printer messages are affected by the Auto Continue and Clearable Warning settings from the Configuration Menu in the printer's Control Panel. 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 [Go] is pressed. If an error occurs that prevents printing and AUTO CONTINUE=ON is set, the printer goes offline for 10 seconds before it returns online. If AUTO CONTINUE=OFF is set, the message displays until [Go] is pressed. Read Only Memory (ROM) Besides storing microprocessor control programs, the ROM stores dot patterns of internal character sets (fonts). 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" on page 5-21). 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. EN Formatter System 5-15
