2.2 High-Resolution Imaging System for Copied and Printed Images
The imageRUNNER ADVANCE 8500 and 8500 II Series provide a high-resolution
imaging system. This system renders images at a 1,200 x 1,200 dpi print resolution,
which delivers the highest level of speed and image quality. Object-optimized
imaging also helps to achieve superior 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 8500 and 8500 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 (±
1.0 mm).
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.
The imageRUNNER ADVANCE 8500 and 8500 II Series also automatically
detect and compensate when there is a deviation from the specified ideal density.
This keeps the density of halftone areas constant, and produces a stable image
without density fluctuations. Patches for keeping the halftone density constant
are applied between every 6,000 sheets on the drum.
