Calibrating the Scanner
If the scanned image looks fuzzy or there are strange stripes on it,
the scanner may need calibrating in order for the sensor to resume
its original precision. To calibrate the scanner:
3. Gently slide the sensor cleaning
swab back and forth from one
end of the output slot to the other
five or six times consecutively.
NOTE
: Do not apply too
much force on the swab.
4. Remove the sensor cleaning
swab from the slot, and store it in
a safe place and protect it from
dust.
1. Follow the instructions beginning on page 19 to clean the image
sensor, and then follow the instructions in "Preparation and
Initial Setup" on page 10 to prepare the scanner for scanning.
2. Insert the calibration card as
shown.
3. The scanner will scan the
pattern on the calibration card
and perform calibration to the
sensor inside automatically.
NOTE
: Make sure that
the calibration card is
inserted in the correct
direction and aligned
against the left side of
the feeding slot.
Otherwise the calibration
won’t work.
