Memory Clients
7-13 Memory Submenu
Increasing the amount of memory in this client may improve printing
throughput and minimize slowdowns due to duplexing, collating, or
printing complex pages. When large jobs are sent to the printer for
multiple collated copies, the printer may collate a chunk — perhaps
50 pages of each copy — before starting another chunk. Increasing
the Display List memory can increase the size of collated chunks so
you have less hand sorting to do.
The Display List is also the excess memory client. Any unallocated
memory is stored in this client. The system will not allow you to set
this memory client too low. The maximum value is 99999 and the
default is Variable.
Disk Cache
Also known as K Mem Disk Cache, the Disk Cache is a high-speed
temporary buffer for data going to and from the hard disk drive. It can
speed the printer in two ways:
■
Information such as fonts or logos that may be referenced
frequently may still be in the cache and may not have to be
pulled off the disk every time it is needed.
■
When writing to disk, information can be held in the cache
temporarily until it is more convenient to write to disk.
For example, if many fonts are stored on disk, they can be accessed
faster by increasing the disk cache size. If no hard disk is used, the
disk cache should be set to zero. However, when hard disks are
installed they are not available until the disk cache client is increased.
The amount of memory needed for the disk cache client depends on
the number of disks and their sizes and on the number of subdirecto-
ries on each disk. As long as there is enough memory in the disk
cache, all disks are accessible. If insufficient memory is allocated to
the disk cache, some disks may be seen while others are not.
» Note: Accessibility of disks is also affected by cabling. See chapter 8,
“Engine, Miscellaneous, and Disk Operations Submenus,” for details
about cabling requirements.
