PTR

PTR Mechanism
The PTR rotates by friction
from the drive of the transfer
belt.
The ITB drive roller
"pushes" the toner off the
surface of the belt, and onto
the paper.
•
The PTR is grounded. It does
not pull the toner off the belt,
as in some models.
The discharge plate removes
charge from the paper after
it goes past the PTR.
•
This allows the paper to
separate from the transfer
belt.
