Selecting a Good Location
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
operates.
•
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
controlled (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
elevator, an air conditioner, or a refrigerator that
produces 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
provide 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.
•
Space
. Find a location that allows you plenty of
working surface around the scanner. See “Scanner
Hardware Features” on page 3 for information on the
scanner’s size.
