loaded outline fonts, and other files. Hard disks also provide virtual memory.
This chapter provides information on installing and using internal and external hard
disks as well as Iomega Jaz and Zip drives.

Caution: It’s very important to protect the printer controller board and any associated
daughterboard or module from electrostatic damage while performing any task
involving the controller board.
If an antistatic wrist strap is provided in your printer option kit, attach one end of it
to your wrist and the other end to any convenient electrical ground (for example, the
bare metal chassis of equipment, as on the back of a computer, that is plugged in but
turned off). Never attach the wrist strap to any piece of equipment with an electrical
current present. Turn off all power switches first. Plastic, rubber, wood, painted metal
surfaces, and telephones are not acceptable grounding points. The printer isn’t an
acceptable grounding point either because it must be unplugged before you perform
this task.
If you don’t have an antistatic wrist strap, discharge your body’s static electric
charge by touching a grounded surface before you handle any printer boards or
components and before removing the controller board. Also avoid walking around
after grounding yourself.

Hard disks, Jaz drives, and Zip drives are identified by their device numbers. If the
printer has an internal hard disk, it has a device number of DSK7. If optional external
hard disks and/or drives are attached, their device numbers can be DSK0–DSK4 or
DSK6. Device numbers of external hard disks and drives can be set by the installer.
