Toshiba e-studio 4511 Manuel D’Utilisation

The e-

STUDIO

3511/4511 is the first full-color MFP system with Twin

Induction Heating (IH) Fuser Technology. With the Twin IH fuser, a

high frequency current flows through the IH coil inside the fuser

roller and produces a high frequency magnetic field. This

magnetic field produces an eddy current in the fuser roller. Then

the resistance element of the fuser roller generates joule heat,

which heats up the fuser roller. Using this method allows the

fuser roller to be heated up directly in a fast and energy efficient

way. This technology breaks the traditionally long warm-up time

commonly found in full-color MFP systems and drastically

reduces the approximate warm-up time to a record-breaking 

40 seconds.

In addition, the TWIN-IH Fuser is designed to optimally control

the fusing temperature and ensure efficient heating. The heat

roller has been reduced to Ø60 in diameter, compared to

Toshiba’s high-end Black & White specific MFP systems where

the heat roller is Ø80 in diameter. This structure allows the entire

fuser roller to be heated evenly. As a result, toner is fused on

paper more evenly.

• Thanks to the Twin IH Fuser Technology, the e-

will be in a ready state almost immediately after it is turned on.

The Twin IH Fuser Technology saves costs by increasing

energy efficiency.

The newly developed toner is fused on paper at a lower

temperature, saving significant amounts of energy particularly

when combined with the Twin IH Fusing system.

Because the toner has a matt finish, it is not only easier to read

but also easy to handwrite annotations on the outputs with pens

or highlighters.

• Users can reduce power consumption and save electricity costs.

• Thanks to the newly developed toner, users can annotate

feedback or comments on an original document with a pen

or highlighter.

The e-

STUDIO

3511/4511 is the first MFP system equipped with 

4 CCD sensors. Dedicated color MFP systems have 3 CCD

sensors, each of which is covered with the R, G, and B filters to

separate the light reflected from an original into red, green, and

blue. Then the R, G, B data scanned by these CCD sensors

undergoes image processing and is converted into C, M, Y, and K

data for copying. In other words, even K or black output data is

created for copying based on the scanned R, G, and B data. On

the other hand, the e-

STUDIO

3511/4511 has not only the CCD

sensors for R, G, and B, but also an additional sensor dedicated

to capturing black data from the reflected light, which maintains

the scan speed comparable to black & white specific MFP

systems and increases sharpness of the black copy image output.

• Thanks to the CCD sensor specifically for black data, users can

obtain sharper, pure black output while maintaining the scan

speed equivalent to black & white specific MFP systems.
