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. For example, a
600 dpi page printed on letter size paper would consume frame buffer
memory space as follows: (600dpi x 600dpi x 8.5'' x 11'')/8 =
4,207,500 bytes or 4.1 M.
Frame buffer memory should always be the first memory client that is
configured in the printer. After this, all other clients can be configured
depending on your printing needs. Anytime the frame buffer client is
changed, all of the other clients will be resized to their default values.
Frame buffer can be configured manually, through the Quick Config
Menu, or by resetting the printer defaults. In all cases, be sure to keep
a copy of the status page as a record of memory client settings. See
chapter 5, “Additional Technical Information,” for more information on
memory and the frame buffer client.

MB Printer Mem, listed as Total Memory on the status page, is the
number of megabytes of RAM available to be split among the various
memory clients. The size of this client's memory limits the number of
jobs that may be queued simultaneously. When this client's memory
is exhausted, the printer slows down, and the hosts are forced to wait.

Depends on the amount of memory installed.
Notes This memory client is not user-configurable.
If disk swapping is enabled (Administration/Memory/
Enable Disk Swap menu), the amount of memory
displayed is larger than the actual amount of memory
installed in the printer.
