Memory
5-11 Additional Technical Information
neously depend on the amount of RAM you have and how that RAM
is distributed. Your printer comes with 8 MB of RAM, upgradable to 64
MB by adding Single In-line Memory Modules (SIMMs).
RAM Disk
Also called a virtual disk, the RAM disk is an area of RAM that is used
to simulate an additional hard disk. Data can be written and read
more quickly than on a hard disk, but a RAM disk loses any informa-
tion stored on it when the printer's power is turned off. The spooling
buffer is a RAM disk client.
SCSI (Small Computer System Interface)
The printer's SCSI (pronounced “scuzzy”) port (located on an optional
SCSI-IDE board) allows you to connect up to three optional SCSI
hard disks, providing storage for fonts, emulations, and other files.
Hard disks are also used to increase the amount of collation that can
be accepted and provide a secondary storage area for spooled data,
while providing virtual memory capabilities.
IDE
The optional SCSI-IDE board allows you to connect an internal IDE
(Integrated Device Electronics) hard disk drive. “Integrated” means
that the controller electronics are on the drive, so no separate adapter
card or expansion slot is required.
Volatile Memory
This type of memory can be lost when the printer loses power. For
example, most RAM is volatile.
Non-Volative Memory
This type of memory is not lost when the printer loses power.
