» 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.
Memory clients in the QMS 2425/2425 TURBO are automatically allo-
cated when the printer is initially installed or when you upgrade the
printer’s memory. The occasions when the printer’s memory is auto-
matically reallocated occur:
„
When the printer is installed.
„
When new system software is installed.
„
When adding or removing hard disks, duplexer, or 1200x1200dpi
daughterboard.
„
When memory is upgraded.
„
When Quick Config is selected in the Administration/Memory
menu.
„
When Disk Swap is enabled or disabled.
„
When Frame Buffer is manually adjusted.
„
When restoring printer defaults in the Administration/Engine/
Restore Defaults/Factory Default menu.

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 in x 11 in) /8 =
4,207,500 bytes or 4.1 MB.
Because the frame buffer memory is so critical to the actual printing
of a page, its allocation takes precedence over that of other memory
