The press operator may perform this procedure. 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. For more information on this feature, refer to the
Automatic Alignment Information .
Note: This feature is available only from the PredictPrint Media 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
PredictPrint Media Manager
.
These Full Width Array quality control measurements and adjustments are automatic after you
initiate them from the
Tools menu on the press control panel or from the
PredictPrint Media
Manager
Profiles feature.
The Full Width Array improves operator and press productivity because it replaces lengthy manual
procedures for press print engine adjustment, saves time from scanning targets with an external
spectrophotometer, and uses simple steps that previously required a service engineer for some
procedures. The Full Width Array can also be used to save time by automatically scanning and
measuring targets when performing print server calibration and profiling initiated from the print
server. For more information, refer to the
System Administrator Guide .
Tip: Before running color-critical jobs, run the Density Uniformity Adjustment procedure and
use the calibration features at the print server to ensure that your press maintains the best
image quality with less or no down time.
Note: Refer to your print server user documentation when performing the calibration workflow
of the print server in conjunction with the print engine. Alignment and registration adjustments
are performed at the print server.

Density Uniformity Adjustment is done to ensure even dry ink/toner density across each page.
The press prints density test patterns, scans them and automatically corrects for variations by
resetting software controls. Uniformity is important for high area coverage applications where density
drift from edge to edge can impact image quality. Density Uniformity Adjustment saves time because
without it a service call is required to make this type of adjustment.
Run Density Uniformity Adjustment to correct inboard to outboard density uniformity defects; for
example, the image quality is lighter (faded) or heavier (thicker) on the left or right sides of the
output (inboard or outboard). Also run Density Uniformity Adjustment after xerographic components
are replaced.
Note: Density Uniformity Adjustment does not require system administrator access and may
be performed by the operator from the press control panel.
