14.6 High-Voltage Power Supply

High-voltage power supply outputs the voltage of positive/negative polarity.

When the voltage of positive polarity is supplied to the 2nd transfer roller, the toner will be supplied from the intermediary belt to the paper.

When the voltage of negative polarity is supplied to the 2nd transfer roller, the toner on the 2nd transfer roller is transferred to the transfer belt reversely. The toner on the transfer belt is eliminated by the cleaning unit and thus cleaning of the 2nd transfer roller is performed.
