6.12.3 ITB LIFT
[A]: ITB lift motor
[B]: ITB lift cam
[C]: ITB lift sensor
[D]: ITB
[E]: Black print position
[F]: Full-color print position
The ITB lift motor [A] (a stepper motor) turns the ITB lift cam [B]. This cam lifts and
lowers the ITB [D]. The operation of the ITB lift motor is controlled by the ITB lift
sensor [C].
When the machine is turned ON, the ITB stays at position [E]. The Y, C, M drums
are separated from the ITB.
When Full Color Mode is Selected:
• The motor turns the cam until the actuator goes into the ITB lift sensor.
• The motor stops.
• The raised cam holds the ITB at position [F]. All drums (Y, C, M, K) contact the
ITB.
• The machine automatically adjusts the paper feed timing for full color copying
with all the drums.
• While the Y, M, C drums are separated from the ITB, they do not turn. This
reduces wear on these drums while they are not being used.
