(2) Primary transfer cleaning unit

The primary transfer cleaning unit is composed of the fur brush, brush cleaning roller, cleaning blade and, cleaning screw.
After secondary transferring is done, the toner which remains in the primary transfer belt is collected back in the waste
toner box. The brush cleaning roller and the fur brush are applied with the DC bias of approximately 500 V DC through the
conductive cleaning frame from the main high voltage PWB. The voltage at the fur brush is approximately 300 V DC.
The toner remaining on the primary transfer belt is transferred onto the fur brush that is biased and continuously revolving.
It is then scraped off of the fur brush by the metal brush cleaning roller in the cleaning frame. The brush cleaning roller has
the cleaning blade which scrapes off the waste toner. The waste toner scraped off of the brush cleaning roller falls onto the
cleaning screw, then driven outward from the cleaning frame.
