Disk Cache
K Mem Disk Cache is the number of kilobytes of RAM dedicated to
the disk cache. This memory client speeds file system throughput on
the hard disks, if one or more are installed, by storing frequently used
data in system memory instead of continually storing it to and retriev-
ing it from a hard disk.
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, all disks are accessible. If
there is insufficient memory 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

Notes » Note:
You may need to decrease one of the
other memory clients before increasing the disk
cache client’s size.
If no hard disk is used, the disk cache should be set to
the minimum. The printer then reallocates this memory
to other clients that need additional memory.
If one or more optional hard disks are used, they remain
unavailable until sufficient memory is available to the
disk cache. You may need to install additional printer
memory. See chapter 6, “Printer Options,” for
information on installing additional printer memory.
If you change the K Mem Disk Cache value, the printer
automatically restarts after you save your changes and
exit from the configuration menu.
