Image Transfer
Belt (ITB)
ITB Cleaning Unit
For each color, the image transfer roller pulls the developed toner
image off the drum.
This makes a four-color toner image on the ITB.
The ITB drive roller pushes the four-toner image from the ITB onto
the paper.
The paper transfer roller is an idle roller, and is not charged.
Slide 197
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.
Used toner collected by the ITB cleaning unit goes to the used toner collection
bottle in the ITB unit. This is separate from the bottle that is used for the drums.
