Preparing for Installation
feeding and stacking of printer paper and/or improper system equipment
operation. Extremely low humidity levels aggravate problems with static
electricity.
Electrostatic Discharge
If there is an abnormally high level of static electricity at your computer
system's location (4 KV or higher), personnel will probably be "sparking"
upon contact with the equipment. Carpeting and/or low humidity will
probably be the source of static electricity, especially in dry and cold
climates. Static electricity can often be significantly reduced by using a
humidifier. Hewlett-Packard recommends a heat evaporating type
humidifier, and strongly recommends against using a cold water
atomizer type humidifier.
Other ways to minimize electrostatic discharge are by using specially
grounded mats in front of the computer system, or by treating carpeting
with anti-static spray. Anti-static spray is not recommended because
it finds its way into the system's intake filter and tends to coat the
circuitry. If spray is used, it should be applied while the system is
turned off.
