Adjusting the Scanner
To adjust the scanner, set the supplied Adjustment Sheet (Shading Sheet) in
the scanner. Orient the adjusting sheet in the direction indicated by the arrow
when setting it in the scanner. After setting the Adjustment Sheet in the
scanner, click the Windows Start button and then click Programs (All
Programs in the case of WindowsXP), Canon Document Scanner, and then
DR-2050C & 2080C Adjustment Tool, or use the scanner adjustment function
of the ISIS/TWAIN driver. Follow the instructions on the dialog box that
appears on the screen to adjust the scanner. Refer to Help for the ISIS/
TWAIN Driver for information about the ISIS/TWAIN Driver scanner
adjustment.
CAUTION
Before performing scanner adjustment, be sure to clean the sensor glass (see
P. 54). Attempting to perform scanner adjustment while the sensor glass is
dirty can cause vertical lines in the scanned image. Note that performing
scanner adjustment will cause previous adjustment data to be deleted. Once
deleted, adjustment data cannot be recovered.
