Transfer Roller Unit

[A]: Transfer roller
[B]: Registration roller
[C]: Transfer belt
[D]: OPC
Transfer from the belt:
The belt transfer roller [E] is given a positive voltage, and this pulls the toner from OPC [D] to the transfer
belt.
After all four layers of toner are transferred to the transfer belt [C], the registration roller [B] turns on and
feeds the paper to the transfer roller [A]. Paper feed is timed to align the leading edge of the toner image
on the belt at 4 mm from the leading edge of the paper. The paper moves at the same speed as the transfer
belt.
Image transfer:
Charged with a negative voltage, the transfer belt drive roller [F] pushes out the toner from the transfer belt
to the paper. This voltage is automatically corrected for the ambient temperature and humidity, print speed,
and paper type.
