Print quality defect locator chart
The print quality locator chart is copied below, but the tool is a transparent sheet available with this printed book.
Use the tables and rulers to determine the source of repeating defects.
Using the chart
Measure repeating horizontal lines from the reference lines at the top to determine what may have caused the
lines to form in that pattern. Be sure to use portrait orientation for the test file.
