Memory
QMS 1660E Print System Reference 4-46
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
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.
