Calibrating the Press
Note
The information contained in this section is about calibrating the press only.
For information about calibrating the print server, refer the System AdministrationGuide
for the press. Also refer to the print server documentation.
Full Width Array
Accessed from the press control panel, the Full Width Array feature calibrates the print
engine only. The in-line Full Width Array adjusts print engine color controls, provides
image density uniformity, and enables print server calibration and profiling without the
need to use an external spectrophotometer.
The Full Width Array uses xerographicparameters and diagnostics to analyze the finished
image and correct errors in output color and density uniformity. This feature uses internal
color calibration strips (or tiles) as reference for known colors of a test pattern. These
color values are automatically adjusted to produce accurate and consistent reproductions.
The Full Width Array is located in the paper path after the fuser and contains an inline
scanner to provide print engine adjustments. The adjustments ensure uniformity of
toner on prints and image alignment.
The Full Width Array provides these two adjustments:
• Automatic Density Uniformity Adjustment: Run this image quality adjustment
when the printed output density is inconsistent (non-uniform) within the printed
page. Non-uniform, inconsistent density may appear as faded colors on portions of
the printed page (jobs running light and dark).
The press operator may perform this procedure, and it does not require system
administrator access.
• Automatic Alignment: This feature adjusts the print image position on paper.
Image-to-media alignment ensures correct positioning of the print image on paper
and is important for calibrating new media. Refer to the Stock Library Manager Help
on the print server for more information on this feature.
Note
This feature is available only from the Stock Library Manager on the print server
and not from Tools on the press control panel. It is available only to system
administrators using the Profiles function of the Stock Library Manager.
These Full Width Array quality control measurements and adjustments are automatic,
once you initiate them from either the Tools menu on the press control panel or from
the Stock Library Manager Profiles feature.
