Calibrating the Scanner
Use the procedure below to make a white calibration.
1. Find the white calibration sheet that came with your scanner. It is a
square white piece of paper (219 x 219 mm (8.6Ó x 8.6Ó)). If you
have lost the white calibration sheet, then you can use a ßat (non-
textured), perfectly white piece of paper of the same dimensions.
2. Your scanner came with several clear plastic layers for the reßective
original holder. If you have used the reßective holder before, check
the plastic layer for Þnger prints or other marks. Replace the layer
with a new one if necessary.
3. Align the top edge of the target with the dotted line near the top of
the original holder. Align each side of the target with the edges of
the original holder. See Figure 7.
