Memory
5-15 Additional Technical Information
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 Admin-
istration/Memory menu. When you allocate memory to a specific cli-
ent through the control panel, it’s allocated in kilobytes (KB). Each
time you make changes in the Administration/Memory menu, print out
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 at engine speed is engine
specific and depends on the size media and resolution. For example,
printing at 600x600 dpi requires four times the amount of memory in
the frame buffer than does 300x300 dpi.
If you are uncertain about how to configure your printer’s memory,
use only the Administration/Memory/Frame Buffer menu. Or use this
menu as a starting point before trying manually to configure your
printer’s memory. It provides a simple method of defining how much
memory should go to each of the clients for the most complicated
printing conditions in your environment. Menu options allow you to
