Memory
5-23 Additional Technical Information
Virtual Memory Support
Your printer supports virtual memory capabilities for the spooling
buffer (Administration/Memory/K Mem for Spool menu) and the dis-
play list (Administration/Memory/K Mem Display) clients when a hard
disk is installed and disk swapping is enabled (Administration/Mem-
ory/Enable Disk Swap menu). These capabilities extend the amount
of memory available for certain supported features, such as spooling
and collation. If all of the memory in the spooling buffer or display list
is being used Enable Disk Swap is enabled, the printer stores the
“overflow” on a hard disk.
» Note: Chunk collation begins automatically after 50 pages regardless
of how much memory is available to the display list client.
Specific Printing Environment Example
Since configuring memory is not an exact science, it may be helpful to
see how others in various printing environments have allocated their
printer memory to meet their printing needs best. The following exam-
ples are to be used only as a guideline for configuring your own
printer's memory.
Example
A QMS 1660 Print System with 12 MB of RAM. As many as 35 people
use this printer, sending text and graphics PostScript files to be
printed on 8.5" x 11" (215.9 mm x 279.4 mm) and 11" x 17" (279.4 mm
x 431.8 mm) media. They have configured their printer to print at
600x600 dpi.
