Introduction
The Image Quality (IQ) section is used to identify an image quality
problem.
The Test Pattern Samples are reproductions of acceptable image quality
of Diagnostic Test Patterns generated by the terminal and Test Pattern
82P151 copied on the terminal.
Use the Image Defect Samples as a comparison to identify any image
quality defects which may have been produced during System Check.
