HP QMS 1660E manual 78

Memory

Notes	If no hard disk is used, the disk cache should be set to the
	minimum. The printer then reallocates the released memory to
	other clients that need additional memory.
	If one or more hard disks are installed and formatted, they
	remain unavailable until sufficient memory is available to the
	disk cache. You may need to do one of the following:
	n Add more memory, which automatically increases the
	disk cache client’s size. See chapter 6, “Printer Options,”
	for information on installing additional printer memory
	(SIMMs).
	n Set Administration/Memory/Enable Disk Swap to Yes.
	Any extra memory is distributed to all memory clients.
	n Take any memory, if available and not being used by
	other clients, and add it to the Administration/Memory/K
	Mem Display memory setting.
	O Caution: This option should be used only by individuals who are
	familiar with adjusting memory client’s values. Incorrect use of
	this option could cause the system to operate incorrectly.
	If you change the K Mem Disk Cache value, the printer
	automatically restarts after you save your changes and exit
	from the configuration menu.

The amount of memory needed for this memory client depends on the size and number of hard disks, the number of subdirectories on each disk, and the amount of memory dedicated to caching.

»Note: If sufficient memory is available to the disk cache, all disks are accessible. If insufficient memory is available to the disk cache, some disks may be accessible while others may not be.

The recommended amount of memory for the disk cache client is n 120 KB minimum

n 0.5 KB per MB of disk storage total for all disks

For example, the recommended amount of memory for the disk cache for a single 120 MB hard disk is 180 KB, and for two 120 MB hard disks it is 240 KB. These are recommended values. The printer
