7. This machine employs a repulsion force bias system for belt to paper image transfer The transfer power pack A applies a negative bias to the ITB bias roller B The negative bias applied to the back side of the ITB forces the toner from the surface of the belt onto the paper This system has two advantages The negative bias has no effect on the moisture in the paper Because the bias is applied from the front side of the paper the bias can be applied more effectively regardless of the level of humidity around the paper After the image has been transferred to the paper The paper discharge plate C connected to the separation power pack applies an ac charge to neutralize the charges on the paper and the ITB Next curvature separation at D separates the paper from the belt when the ITB makes 202 its abrupt turn toward the top of the machine for the next copy cycle PTR Cleaning temp ptula A PTR brush cleaning roller C PTR cleaning blade PTR toner collection coil E Lubricant bar ZnSt F PTR lubricant brush roller 203 The PTR A turns counter clockwise The brush cleaning roller B driven by the PTR motor removes toner from the PTR The PTR cleaning blade C removes any toner remaining on the surface of the PTR after brush cleaning Toner removed by the brush cleaning roller and cleaning blade falls into the PTR toner collection coil D This rotating coil moves the toner to
