Use the
Clean Toner
procedure after running a low area coverage job followed by large area
coverage job, which caused toner agglomerates and clumps on the output prints. The press runs a
full-page halftone to purge the debris and any residual dry ink/toner from the system.
Note:
It is recommended that you run a few test prints before performing the cleaning
procedure. After the
Start Cleaning
button is selected, the system automatically generates a
test print. This allows you to compare the before and after prints for image quality.
1. At the press control panel, log in as the administrator.
2. Press the
Machine Status
button.
3. Select the
Tools
tab.
4. Select

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 xerographic parameters 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 dry ink/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).
