Image Transfer
Belt (ITB)
ITB Cleaning Unit
For each color, an image transfer roller "pulls" the developed toner
image off the drum and onto the surface of the transfer belt.
This creates a four-color (full color) toner image on the ITB.
The ITB drive roller then "pushes" the four-toner image from the ITB
onto the paper.
•
The paper transfer roller is an idle roller, and is not charged.
All four color toners are pulled onto the ITB on the same rotation of the ITB.
The paper transfer roller does not pull the toner off the ITB. In this machine, the ITB
drive roller pushes the toner off the ITB and onto the paper.
