HP QMS 1660E manual 81

Memory

Notes	If disk swapping is enabled and the system hard disk is
	removed or not turned on, the printer automatically resets to
	the factory defaults. It is then necessary to re-enable disk
	swapping if you want this functionality.
	Before you install printer options, such as fonts and macros,
	ensure that the printer has enough memory, or they may not all
	be available for use. If it doesn’t, you can install SIMMs (see
	chapter 6, “Printer Options”) to increase printer memory, or you
	can install a hard disk (see chapter 6, “Printer Options”) and
	enable disk swapping.
	The printer must be restarted for changes to the Enable Disk
	Swap menu to take effect. You can either let the printer restart
	automatically after you save the change and exit from the
	configuration menu, or you can wait for the change to take
	effect the next time you manually turn on the printer.
	If you enable disk swapping and restart the printer, the disk
	cache size automatically increases to 256 KB.

Frame Buffer

The Frame Buffer memory client holds rasterized or bitmapped images of page faces which are ready to be sent to the print engine. A frame holds the contents of each single page image.

If you are uncertain about how to configure your printer’s memory, use only the Administration/Memory/Frame Buffer menu. Or use this menu as a starting point before trying manually to configure your printer’s memory. It provides a simple method of defining how much memory should go to each of the clients for the most complicated printing conditions in your environment. Menu options allow you to specify the largest media size you plan to use for each resolution. Memory is then automatically allocated to the clients that require it. Any excess memory is allocated to the excess memory client. See chapter 5, “Additional Technical Information,” for more information on memory and the frame buffer client.
