Transfer Belt Cleaning - Ricoh B230 Training Program

Cleaning Brush
Coil
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 always contacts the image transfer belt, and removes
used toner from the belt. The cleaning blade in the cleaning unit scrapes the
toner off the image transfer belt. Then the toner collection auger transports the
toner towards the toner collection duct.
The lubricant application roller applies lubricant to the image transfer belt to
make toner removal easy.
