Precautions
3. Never enter an IP address in RIP Station 5000 Network Setup.
Only the network administrator should enter an IP address on a network device.
Assigning a RIP Station 5000 an incorrect IP address can cause unpredictable errors on
any or all devices connected to the network.
4. Always disconnect power before opening the RIP Station 5000 chassis.
Although RIP Station 5000 circuitry operates on 3.3V DC, 5V DC, and ±12V DC,
100-240V AC is present when the chassis cover is removed. Inside the chassis, the power
supply is not encased. Before you service the RIP Station 5000, shut it down completely
(at Idle, power it off ) and unplug the AC power cable from the back.
5. Handle the RIP Station 5000 lens with care.
The lens on the RIP Station 5000 Control Panel is made of plastic. Use a soft cloth
moistened with water to clean it. Other solvents, such as alcohol, may damage the lens.
An air brush is recommended to remove dust particles if any adhere to the inside of the
lens during service.
6. Handle the RIP Station 5000 glass display window with care.
If the glass on the user interface board breaks and the liquid crystal inside leaks out, avoid
contact with it. If you do come in contact with the liquid crystal, wash it off with soap
and water immediately.
Avoid pressing the surface of the glass display window. Applying pressure to the glass
display window on the user interface board will cause it to change color.
Use a soft cloth moistened with isopropyl or ethyl alcohol to clean the glass display
window. Other solvents, such as water, may damage the polarizer.
7. Follow standard ESD (electrostatic discharge) precautions while working on the internal
components of the RIP Station 5000.
Static is always a concern when servicing electronic devices. It is highly unlikely that the
area around the printer and the RIP Station 5000 is static-free. Carpeting, leather-soled
shoes, synthetic clothing fibers, silks, and plastics may generate a static charge of more
than 10,000 volts. Static discharge is capable of destroying the circuits etched in silicon
microchips, or dramatically shortening their life span. By observing standard precautions,
you may avoid extra service calls and save the cost of a new board.
When possible, work on a ground-connected antistatic mat. Wear an antistatic
wristband, grounded at the same place as the antistatic mat. If that is not possible:
• Attach a grounding strap to your wrist. Attach the other end to a good ground.
• When you unpack the RIP Station 5000 from the carton for the first time, touch a
metal area to discharge the static on your body.
