1. Color image formed on ITB is transferred onto media by T2 process
2. T2 voltage is also positive to get color image moved onto media
3. Toner remained on ITB after T2 process is cleaning by ITB cleaning blade and collected and
4. Transported and retrieved into waste toner box by auger and belt driving system
5. T2 Roll is engaged when color image is being transferred onto media. Otherwise it is disengaged. Clutch is used
for driving T2 Roll engagement and disengagement
Fusing
3 Roll system
-> short warm-up time (45sec)
Post Pressure Roll
1. Color Image on media is melted down and fixed into media by fusing process
