IT bit Technology
S.E.A.D. (Screen-Enhancing Active Digital
Processing) is the core image processing
technology behind the bizhub PRO C6501.
This image processing system works
closely with the machine’s optics,
developing unit and other processes to
emphasise each component’s unique
characteristics and make possible a
comprehensive, high-class image processing
environment.

Newly Engineered Simitri HD
Polymerised Toner
The particles in Simitri HD toner are extremely
small and consistent in shape, ensuring
improved colour photo and illustration quality
and clear reproduction of text and line
drawings. The smooth outer surface and
evenly dispersed wax and colour pigment
offer a great hold and a consistent finish for
high image quality across diverse media.
Increasing the value of documents, stabilising text and images for print
1,800 dpi equivalent x 600 dpi
resolution
Thanks to exclusive smoothing technology,
documents can be output at a stunning 1,800
dpi equivalent x 600 dpi resolution.
Text Enhancement
During printing, text data is isolated from
image data and processed to best enhance
reproduction. Detailed outlines are precisely
defined, while reversed text and fine text are
optimised to clearly stand out.
Better Registration Accuracy for Two-sided Printing
Robust ADU Design
The ADU is built on a sturdy steel chassis for
precise, stable performance. An additional
conveyance roller reduces skew of thick and
coated paper, while increasing overall paper
feed capability.
Fine-tuning Image Placement and
Registration
From the touch panel, users can make slight
adjustments to image position (in 0.1mm
increments), and magnification (in 0.01%
Oil-less Fusing System
A special compound fusing process delivers
high-quality, low-gloss output that allows you
to easily write with a pen on virtually any
document.
Superior Colour Reproduction
Range
Simitri HD toner provides a wider
reproduction range across the entire colour
spectrum. Most notably, there is visible
saturation between yellow and red.
High Durability
New Simitri HD toner offers resistance to
fading comparable to offset ink and excellent
resistance to peeling compared to other
MFPs. Documents can be stored for long
periods of time and still retain the same high
image quality as the day they were printed.
Low Temperature Fixing Reduces
Paper Stress
The bizhub PRO C6501 affixes Simitri HD
toner using less heat energy than previous
models. By reducing excess heat, this fixing
process minimises paper stress.
Detailed Reproduction of Small
Characters
A newly developed technology controls the
screen by adjusting exposure time of the
engine’s lasers. Even text at small point sizes
are not only legible, but very clear.
Stable Image Quality and Colour
Alignment
The transfer belt features an optical sensor to
monitor the density of toner and provide
instructions such as adjusting laser strength
and screen gradation to maintain consistency
and precise coverage, even during long runs.
At the same time, optical sensors monitor the

IT bit (Image Tag bit) Technology
A collection of four technologies, (1) laser
exposure with nanosecond pulse control for
precise dot placement of each colour, (2) dot
position control to write in fine resolution
(1/256 of total dot width) for detailed edges of
fine lines and text that runs together smoothly,
