1.3.7 Tertiary transfer (IDT 2 - paper)
In the tertiary transfer process, finished toner image formed on the IDT 2 surface is
transferred onto the paper under the voltage supplied to the transfer roll cartridge.
•
Transfer roll cartridge is composed in the transfer roll cartridge ASSY.
Transfer roll cartridge is a conductive roll and receives positive high current from
HVPS.
When paper passes through between IDT2 and transfer roll cartridge, plus potential
is given to the back side of the paper so that the toner on the IDT 2 is transferred
onto the paper. At this time, potential on the transfer roll cartridge is higher than
that on the IDT 2.
