Transfer belt cleaning

The ITB-cleaning unit removes toner (during printing) and the ID sensor patterns (during

process control or automatic line position adjustment) on the belt. Belt cleaning is

completed while the image transfer belt makes one rotation. The ITB drive motor drives the

ITB-cleaning unit.

The cleaning brush [A] always contacts the image transfer belt [B], and removes used toner

from the belt. The cleaning blade [C] in the cleaning unit scrapes the toner off the image

transfer belt. Then the toner collection auger [F] transports the toner towards the toner

collection duct.

The lubricant application roller [D] applies lubricant [E] to the image transfer belt to make

toner removal easy.

To drive the cleaning unit, the transfer belt rotates gear [G], and gears at the front of the

transfer unit drive the auger [F] and the rollers [A, D] in the cleaning unit.
