# This mechanism is necessary because the roller in the ITB unit that opposes the
PTR is made of a softer material than in the V-C1. The PTR will deform this roller
if it always contacts it.
PTR Lift Mechanism
! The mechanism raises the
PTR against the ITB for
image transfer.
! The mechanism lowers
the PTR and pulls it away
from the ITB when the
machine is not printing.
! The PTR lift motor rotates
a cam. The cam raises and
lowers the lift plate, which
raises and lowers the
PTR.
