1.1.2 Carriage (CR) Mechanism
The major components of the carriage (CR) mechanism are the CR Unit, CR Encoder Sensor, CR Scale, CR Motor, and CR Timing Belt. The CR
mechanism is a key mechanism to ensure stable print quality because printing is performed by moving the CR Unit from side to side.
As shown on the right, Main Frame is holding the upper side and the lower side of the CR Unit. The CR Unit is attached to the CR Timing Belt that is moved
by the CR Motor so that the assy can move from side to side to print. The position and speed of the CR Unit are always monitored by the CR Encoder
Sensor and the CR Scale, and the CR Motor is controlled in accordance with the information acquired by the CR Encoder Sensor.
