About scanner maintenance

Scanner maintenance will ensure optimal performance of your scanner.
There are three basic maintenance tasks:
Cleaning
1.
Keep your scanner clean – the next section describes how to
thoroughly clean the internal scan area. How often you need to clean
the scanner will depend on how often and the types of media you
scan. If your work primarily involves scanning newspapers and old
blueprints you may need to clean more often than users who only scan
brochures and new drawings.
Be sure to clean the scanner when results are not optimal. Particles of
dust in the scan area can often be the cause of streaks in the end
result.

Calibration and camera alignment
2.
Scanner Calibration is easy to perform and most of it is completely
automatic. Scanner calibration includes camera alignment and
calibration of B&W and color parameters. To run, you insert a
Calibration Sheet, and start the Scanner Maintenance program. Be
sure to calibrate if your output is not optimal. Make sure the scanner is
clean before calibrating.
See more under the section Camera alignment and

This should be carried out when you get a warning on your screen or
when a worn part affects your results. Replaceable parts are:
a. the glass plate
b. the lamp
c. the white background platen
d. the dust filters
