The Intellifont SIMM
» Note:
If you’re installing a RAM SIMM, see “Single In-Line Memory
Modules (SIMMs)” on page 23 for instructions. Intellifont SIMM and
RAM SIMM connectors are not interchangeable.
An optional Intellifont SIMM increases the number of fonts available
to the HP PCL 5 emulation on your printer from 20 to the 37 PCL 5
fonts available on a Hewlett-Packard LaserJet 4Si.
WARNING!
Turn off the printer and unplug the power cord before
taking the cover off the printer.
ACHTUNG!
Bitte schalten Sie den Drucker aus und ziehen Sie den
Netzstecker heraus bevor Sie die Druckerabdeckung öffnen.
Caution:
It's very important to protect the printer tray assembly from
electrostatic damage while performing this task.
If an anti-static 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 anti-static 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 tray assembly
cover. Redischarge your body each time after walking around and
before touching the printer tray assembly again.
1 Follow the instructions in “Removing the Controller Board”
on page 20, being careful to discharge electrostatic buildup
before you begin.
