Printing the chart
The printer has an internal copy of the defect locator chart under the Help Menu. Verify the proper image size by
measuring any of the marks on the chart and comparing them to the corresponding measurement in the chart.
Use Step 2 if adjustments are needed.
Copying the chart
Use the provided transparent sheet if at all possible. If you need to make a copy, be aware that fax machines,
digital scanners, and xerographic copiers can distort images. Charts should be printed using the transparent
copy provided in the service manual. In order to maintain the accuracy of the edge rulers, the following steps
should be heeded when printing a copy of the Defect Location Chart.
1.
When printing this document, make sure "Fit to page" is not selected.
2.
Measure the distance between the Reference line and the 110 mm Calibration Mark to verify that it is
correct. If the distance is inaccurate, the bottom registration margin setting can be adjusted to correct the
discrepancy. Increasing the bottom margin value stretches the image, reducing it shrinks the image.
Original margin settings should be noted in the case that these changes adversely effect the print quality or
registration when printing normal documents.
