Print quality
For a transparency of the defect locator chart, go to the back of the hard copy service manual.
Note: If you want to copy the chart, then the following should be observed.
Since 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 the 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 the bottom margin value
shrinks the image. Original margin settings should be noted in case these changes adversely effect the
print quality or registration when printing normal documents.
