TPU Carriage Drive Mechanism Operation
The TPU Carriage Unit slides along the guide shaft in the secondary
scanning direction as the TPU CR (Carriage) Motor transmits its drive
power to the TPU CR Drive Belt connected to the TPU Carriage Unit.
See Figure 2-6. The TPU CR Motor uses a stepper motor and is driven
under open loop control.
