Cleaning Bias Control
To return the toner adhered on the transfer roller to the photosensitive drum, negative voltage
is applied at the last rotation.
Separation Static Eliminator Bias Control
Either of the two types of negative voltage (low bias or high bias) is applied to the static
eliminator depending on the print mode and sequence for reducing electrostatic suction to
facilitate separation of paper from the photosensitive drum.

Waste Toner Box
Residual toner adhered on the photosensitive drum without being transferred to a paper is
scraped off by the cleaning blade in contact with the photosensitive drum, then fed into the
waste toner box by the waste toner feed screw.
The waste toner box is supported by a spring. If the waste toner box sinks down lower than
specified with the weight of collected toner, the waste toner full sensor (S17) detects the
waste toner box full.
