Scanner Adjustment Clause Samples

Scanner Adjustment. You should set the adjustment features if you want to approximate the accuracy of the scanned- in drawing to that of the original. (Fine-tuning the accuracy, depending on the quality of the document.) Usually this adjustment is unnecessary. You can adjust the scanner (Distance Correction, Joint Fine-adjustment, and Trapezoidal Correction) by selecting the Tools menu > Adjust Scanner. The settings that can be specified vary according to the scanner model. Corrects distances as appropriate for the type of document. The setting may be within approximately ±1%. It is effective until the scanner is powered off. To use the Distance Correction function, you must first measure a vertical line drawn on the document using the following procedure: (1) Select a document that contains one or more drawn vertical lines. Scan it in at 600 dpi in portrait orientation. (2) Measure the length of the vertical line on the document. Define it as x (Distance Measured on Document). (3) Using the View menu > Relative Measure > Distance between Specified Points, mea- sure the length of the corresponding vertical line in the image data. Define it as y (Distance Measured after Scanning). (4) In the Scanner Adjustments window, click the Distance Correction button in Adjust- ments. The Distance Correction window appears. (5) Type in the Distance Measured on Document x and Distance Measured after Scanning y values. These values must be within the range of distance correction. (6) Click the OK button to calculate the corrections. Distance correction will take effect from the next document scanned.
