Calibrating the scanner
If scanned images look fuzzy or there are unwanted lines on them,
then the scanner needs to be calibrated in order for the sensor to
resume its original precision. To calibrate the scanner:
3. Gently slide the sensor cleaning
swab to the other end of the
output slot.
4. Repeat step 3 five or six times
consecutively.
NOTE
: Do not apply too
much force on the swab.
5. Slide the sensor cleaning swab to
the left end of the output slot,
and then remove it from the slot.
Store the sensor cleaning swab in
a safe place and keep it away
from dust.
1. Follow the instructions on page 17 to clean the image sensor.
2. Turn on the scanner and then insert
the calibration card as shown. The
scanner will scan the pattern on the
calibration card and calibrate the
sensor inside automatically.
NOTE
: Make sure that the
calibration card is inserted in
the correct direction. Otherwise
the calibration won’t work.
