Transfer Roller -
The Transfer Roller is driven by the drum gear, coming into contact with
the drum of the toner cartridge.
The Transfer Roller applies the positive charge onto the back of paper when paper moves
between the Transfer Roller and drum. A negatively charged toner image is drawn by the
positive charge on the backside of paper, and transcribed from the drum surface to the
paper face.
Metal and Rubber Registration - Roll rotation is controlled by the registration roller clutch,
and paper is positioned with an image of the drum surface.
Detack Blade - Applies the negative charge to the back of paper to partially neutralize the
positive charge, and cast off paper from the drum surface.
Varistor - Installed between the frame and Transfer Roller, this component helps reduce
noise that can alter the voltage level on the Transfer Roller.
Toner Low Sensor - Residual toner in the toner cartridge is measured with the
electromagnetic sensor and a warning for replacement is issued (optional).
