2.2 High-Resolution Imaging System for Copied and Printed Images
The imageRUNNER ADVANCE C5500 and C5500 II Series provides a
high-resolution imaging system. This system renders images at a 1,200 x 1,200 dpi
print resolution. Object-optimized imaging also helps to achieve the desired print
quality. Text and lines are processed with a high-priority given to resolution, and
images and graphics are processed with a high-priority given to gradation. This
high-resolution imaging system, coupled with the Density Detection Adjustment
mode, a feature that refines thin, fine text, and lines while the device is rendering
images at 1,200 x 1,200 dpi, minimizes faint output and delivers quality prints.
2.3 Image Stabilization Control
The quality of printed images is affected by changes in the environment, such as
temperature and humidity in which the machine is installed. Image quality is also
affected by the deterioration of image formation parts through extended use. The
imageRUNNER ADVANCE C5500 and C5500 II Series reduces these issues,
stabilizes image production, and maintains consistency with features, such as the
Auto Gradation Adjustment mode, Density Detection, and accurate registration
(1-Sided: ± 1.5 mm), (2-Sided: ± 2.0).
2.3.1 Automatic Gradation Adjustment
Automatic Gradation Adjustment is a function that helps to automatically adjust
toner density. Select from the Quick Adjustment mode or Full Adjustment mode.
The Quick Adjustment mode quickly and simply adjusts the gradation and density
by performing calibration without outputting test prints. The Full Adjustment mode
performs a precise calibration by outputting and scanning test prints. For more
information on the Automatic Gradation Adjustment modes, see
“Adjustment/Maintenance,” in the Settings/Registration e-Manual included with
the machine.
2.3.2 Automatic Calibration
Automatic calibration helps to maintain color consistency by making automatic,
real-time adjustments during print runs. Density level measurements of cyan,
magenta, yellow, and black toner are taken every 100 pages during a print job.
The patches of each color are imaged on the ITB (Intermediate Transfer Belt),
and sensors measure the density to adjust the toner gradation and density.
2.3.3 Accurate Registration
Image registration can be finely adjusted by manually specifying an exact
adjustment value for every user-specified paper type. For more information, see
the e-Manual included with the machine.
