# The pressure roller and hot roller are only in contact during printing. This
increases the life of the rollers.
# If the pressure roller remains pressed up against the soft sponge material of the
hot roller while the machine is idle, this could permanently warp the shape of the
soft hot roller and cause problems during image transfer from belt to paper.
