Introduction
The quality of the printer's output is always subject to the judgment of the particular user. This
section of the manual is intended
to
assist the service representative in defining print quality and
understanding what factors may affect print quality.
The print samples depicted in Figure 7-24 illustrate some print quality defects and their possible
causes. It is impossible to illustrate dl possible print quality defects since there are too many
variables in the printing process. It is recommended that the service representative keep copies of
print quality defects with an explanation of their muses for future reference.
