Selecting a Good Location

Selecting a Good Location

38
To place your scanner in a good location, observe these
requirements:
• Air quality. Keep in mind that a scanner works better
and lasts longer when it is not exposed to a lot of dust.
• Computer hookup. Place the scanner within 6 feet of
the computer to which it is to be connected.
• Flooring. Try to find a location for the scanner that is
not carpeted. Most types of carpeting introduce static,
which might interfere with the way the scanner oper-
ates.
• Humidity. Use the scanner in a location having 40%
relative humidity. If sheets have been in very wet or
dry conditions, keep them in an atmosphere con-
trolled (60º to 80º Fahrenheit or 15º to 27º Celsius
with 40% humidity) environment for 24 hours before
you attempt to scan them.
• Electrical noise. Do not locate the scanner near a
generator or other type of large motor, such as an ele-
vator, an air conditioner, or a refrigerator that pro-
duces electrical noise which might interfere with the
operation of the scanner.
• Phone access. Locate the scanner close to a phone
— in the same room if possible. Close phone access is
important if you need to call Scantron for assistance
with a scanning problem. Customer Support will pro-
vide assistance over the phone.
• Power source. Place the scanner in a location that is
close to an electrical outlet that provides stable power.
The outlet must be properly grounded and meet
national and local electrical codes.
Scantron recommends having a separate source of
power (with surge protection) for the scanner. Do not
connect the scanner to an outlet that also serves other
equipment except for a computer. The circuit from
the source (breaker box) should not supply power to a
major piece of equipment other than the scanner.
