Memory
QMS 1725E Print System Reference 5-12
After you have answered all of these questions, read the following
sections to find out which memory clients control features you plan to
use and which memory clients control features you don’t need.
Memory Clients
Memory clients are users of printer memory that are dedicated to a
specific purpose. Each of the memory clients is located in the
printer’s Administration/Memory menu. When you allocate memory to
a specific client through the control panel, it’s allocated in kilobytes
(KB). Each time you make changes in the Administration/Memory
menu, print a status page to confirm the memory reallocation.
» Note: The value for each memory client must be divisible by 4 KB. Therefore, if
a value is entered that is not evenly divisible by 4 KB, it’s automatically
converted to the next lower value that’s divisible by 4 KB. For example, if you
enter 102 KB, the actual value is lowered to 100 KB, assuming there is
enough memory available to allocate to this client. See the “Memory”
section of chapter 4, “Printer Configuration,” for each memory client’s
minimum and default settings.
Frame Buffer
The Frame Buffer memory client holds rasterized or bitmapped
images of page faces which are ready to be sent to the print engine.
A frame holds the contents of each single page image.
Because the frame buffer memory is so critical to the actual printing of
a page, its allocation takes precedence over that of other memory cli-
ents. The number of frames needed to print is engine speed specific
and depends on the media size and resolution. For example, printing
at 600x600 dpi requires four times the amount of memory in the
frame buffer than does 300x300 dpi.
The Administration/Memory/Frame Buffer menu provides a quick and
simple method of defining how much memory should go to each of
the clients for the most complicated printing conditions in your envi-
ronment. Menu options allow you to specify the largest media size
you plan to use for each resolution. Memory is then automatically
allocated to the clients that require it.
