Symptom Applicable Tests
l Image Quality is Poor The most common image quality problem for copy jobs is
caused by glass that is dirty. Before you perform any tests,
clean the glass.
The second most common image quality problem is caused
by selecting the incorrect image quality type when using any
of the image quality adjustments found in the Image
Adjustment tab.
Image Quality Tests and Patterns. These specially
designed patterns and tests are used to verify that the device
is producing the optimal image quality. Each pattern tests a
different image feature and is designed to be interpreted by
the Welcome Center or an authorized technician.
Xerographic System Routine. The Document Centre
automatically adjusts the Xerographic module to enable
optimal Image Quality. This selection allows you to
manually initiate the Xerographic Routine.
