2. Printing Principle

Xerografical Principal
1. Charging of drum
2. Discharging with LASER
3. Toner transfer to drum

PxP Toner
Oil free dry-toner
Particle size only 5 µm
Active toner control for constant density

Different Printing Resolutions
Vertical Cavity Surface Emitting Laser
High resolution of 1200 x 4800 dpi
40 laser beams on 1mm²
Laser
High resolution of 1200 x 1200 dpi

C751 – Technology
Charging by rollers – no corona wires
No ozon generation
Low energy demand
Image Transfer Belt
Charging roller
Fusing unit
C 751
Technology

C751 – AC Technology
AC Technology enables a better toner transfer onto structured paper for better toner adhesion
(standard in factory shipped machines from Jan 2013 – retrofit available in march 2013)
stuctured print material
toner is partially transferred to the media.
Toner will be flicked to ITB and increase adherence ability of other toner.
Image Transfer Belt
more toner can be transferred to the media
accumulating currency over time
Toner particles

3. Paper Path

Paper Path

Paper Feed
Friction rollers
