New ITB/PTR Separation Mechanism
 The cams are rotated down to separate the bias roller and
the PTR at the following times:
 Ready mode. After the machine enters Ready mode. This
keeps the PTR separated from the bias roller. If the rollers
were to remain in contact while the machine is idle, the hard
surface of the PTR would deform the shape of the soft bias
roller.
 Thick Paper. Just before thick paper enters the nip of the
bias roller and PTR, the cams are rotated down briefly to
widen the nip for the thicker paper, and then rotated up
again to close the nip. This action eliminates "shock jitter"
which can occur when the leading edge of thick paper
enters a narrow nip.
 Belt Lubrication Mode. The cams are rotated down to open
the nip for lubrication of the belt after the ITB has been
replaced, for example.
 The cams remain up and the rollers pressed together in all
other cases, for color and monochrome printing, process
control, and MUSIC adjustments, and so on.
