The disk cache stores frequently used data in system memory instead of continually
storing and retrieving it from a hard disk. If a hard disk is used and a lot of disk access
is required, adding memory to the disk cache may increase the printer’s performance.

Purpose
Sets the number of kilobytes of RAM dedicated to the disk cache, which
speeds file system throughput on any installed hard disks by storing
frequently used data in system memory instead of continually storing it to
and retrieving it from a hard disk.

Notes
If no hard disk is installed, the disk cache is set to the minimum value
(00000. The printer then reallocates the released memory to other clients
that need additional memory.
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.
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

120 KB minimum

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.
If you change the K Mem Disk Cache value, the printer automatically restarts
after you save your changes and exit from the configuration menu.
