divisible by 4 KB, it is automatically converted to the next
lower value that is 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 chapter 4, the “Administration /
Memory” section, for the minimum and default settings
for each memory client. The amount shown on the status
page will then be 102,400 (100 x 1024).
Frame Buffer
Also known as K Mem Framebuff, the frame buffer memory client
holds rasterized or bitmapped images of page faces which are ready
to be sent to the physical print engine. Any task that affects the page
faces—such as increasing paper size or printing at a higher
resolution—may require increasing the amount of memory
allocated to this client to boost print speed and overall system
throughput. If not enough memory is allocated to this client,
memory is taken from the display list to complete a print job.
A frame holds the contents of a 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 clients.
Therefore, you cannot set the frame buffer to an amount smaller
than that required to image a page of the selected size.
The number of frames needed to print at engine speed is engine
specific and depends on what paper size you are using, and at what
resolution. For example, printing at 600 dpi requires four times the
amount of memory in the frame buffer than does 300 dpi.
