7-5 Memory Submenu
Non-volatile Memory—This type of memory is not lost when the
printer loses power.
NV RAM—This is a protected form of RAM, used to store information
such as your printer’s Configuration menu. Configuration options you
have chosen, such as emulations, memory settings, and input bins,
are saved to this non-volatile RAM. This information is not lost when
you turn off your printer.
Physical Memory—The physical memory on your printer is equal to
the amount of RAM installed.
Virtual Memory—Virtual memory extends the effective size of the
printer’s memory by using a disk file or swap file to simulate additional
memory space. It enables the hard disk to accept data swapped from
RAM, temporarily freeing the RAM for other tasks.
Spool —Spooling is temporary storage to hold print jobs until the
printer is available to process them.
Evaluation of Your Printing
Environment
The first step in allocating your printer’s memory is to define your
printing needs. Each of your printer’s features requires a minimum
amount of memory. If you use a feature, you must allocate enough
memory to the client which controls it. On the other hand, if there are
features you do not use, you can take excess memory from the cli-
ents which control the unused features and add it to other clients that
need additional memory.
