Table 4-7 Item IO BUFFER [IO SIZE] RESRCSAVE Memory Configuration Menu This menu contains the items for personality Resource Saving and I/O Buffering. Depending on how your printers memory is configured, any combination of menu items and possible values can appear. See Chapter 6, PostScript Printing for additional information. When you change an item in this menu, the printer automatically resets, and all fonts, macros and downloaded data in the printer are lost (except data stored on the optional PostScript Disk Accessory). Memory Configuration Menu items can be selected only from the printers control panel. Memory Configuration Menu Items Options AUTO*, OFF, ON 10K and up AUTO*, OFF, ON Explanation The I/O buffer is a portion of the printer's memory set aside to hold incoming data. When this item is set to AUTO, the memory set aside for I/O buffering is automatically determined by the printer based on available memory. When it is set to ON, the size can be manually adjusted. When it is set to OFF, no memory is set aside. If you have a 4MV printer it was set to OFF at the factory. (See "How I/O Buffering Improves Performance" in Chapter 5.) When IO BUFFER is set to ON, I/O SIZE appears in the menu. Use this item to add or reduce I/O buffer memory in increments of 10 KBytes up to 100 KBytes, then in 100 KByte increments. This item appears when a certain amount of memory and a personality SIMM are installed in the printer. If it is set to AUTO, the printer automatically determines the amount of memory to allocate to installed personalities (languages). When it is set to ON, additional memory management item selections appear for each installed personality (see next item). When it is set to OFF, no memory is allocated and personality-dependent resources (such as fonts) are lost when personality changes. If you have a 4MV printer it was set to OFF at the factory.
