• The head lift motor rotates the cam (2) and raises the carriage unit (3) with the cam pressing
against the bottom of the carriage.
• Head limit sensor (4) detects the actuator when the carriage is lifted to its setting point and stops the
motor.
• When the carriage unit is raised to the selected height, the cam locks in place and the carriage unit
disengages from the head lift motor.
