HP QMS 1660 manual 80

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 used, they remain unavailable
	until sufficient memory is available to the disk cache.
	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 will still operate with a smaller cache, but decreased performance may result.

Display

The K Mem Display memory client is the number of kilobytes of RAM dedicated to the display lists. The display list holds the intermediate representation of pages to be printed.
