2) Refresher and RTC
High voltage of the polarity (negative) reverse to that at the printing transfer is
applied to the IDT1, IDT2, and transfer roll cartridge. At this time, the drum surface
is charged negatively by negative voltage of the IDT1. The toner (positive polarity)
remaining in the Refresher and RTC are move to the drum electrically by
transforming the Refresher and RTC to 0V. Then, in the same manner as in the
printing transfer, the residual toner is collected to the transfer roll cartridge surface
by potential difference between IDT1, IDT2, and transfer roll cartridge.
•
Toner attached to the surface of transfer roll cartridge is scraped off with the
transfer roll cartridge cleaner which is in contact with the transfer roll cartridge and
collected into the collection space in the transfer roll cartridge unit ASSY.
