ROM (Read Only Memory)
This type of memory contains data and/or machine-executable
instructions that can be read but not modified. On your QMS 860
Print System, the operating system code, resident fonts, and
resident emulations are stored in ROM. This information is not lost
when the printer’s power is turned off.
RAM (Random Access Memory)
RAM is the memory your printer uses to perform each task. It can
be written to and read from. Once a task is complete, the memory
is free again to be used for another file. This memory is volatile, so
if your printer loses power while a file is being sent, you must
resend the file. The number and type of features you can run on
your printer simultaneously depend on the amount of RAM you
have and how that RAM is distributed. Your printer comes with 12
MB of RAM, upgradable to 32 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
information stored on it when the printer’s power is turned off. The
frame buffer and spooling buffer are RAM disk clients.
SCSI (Small Computer System Interface)
Pronounced “scuzzy,” the printer’s SCSI port allows you to
connect up to seven hard disks, providing storage for fonts,
emulations, and other files. Hard disks are also used to increase the
