3.4 Distance Correction
Corrections to the distance can be achieved using the driver software. The driver software included
with your scanner (“Scanning Master Pro Color”) enables you to perform distance correction from the
menu Tool
→
Adjust Scanner in order to adjust the scanning accuracy.
The adjustment function must be set up when a scanned drawing needs to approximate the accuracy
of the original drawing closely. (This is for making
fi
ne adjustments to the accuracy of the scanned
drawing to suit the quality of the paper being used.) It is not normally necessary to perform this
adjustment.
Adjustment method
Perform the distance correction process according to the type of document to be scanned.
Distance correction can be set in a range of ±1%, which remains effective until the scanner’s power is
turned off.
The practice of distance correction necessitates that you measure a vertical line drawn on the
document before following the procedure described below.
(1) Choose a document that has one or more vertical lines drawn on it and scan it at a resolution of
600 dpi (Portrait (vertical) format).
(2) Measure the length of the vertical line of the document and classify it as x (distance on the
document).
(3) Measure the length of the same vertical line in the image data using the command to measure the
distance between two speci
fi
ed points of relative measurement, and classify it as y (distance after
the scan has taken place).
(4) Click on the Distance Correction button in the Adjust Scanner window to open the Distance
Correction window.
(5) Enter the value “x” (distance on the document) and the value “y” (distance after the scan has taken
place) in this window. The values entered here must be within the range of the distance correction.
(6) Click the OK button to calculate the correction value. The distance will be corrected the next time
a document is scanned.
