OPERATING PRINCIPLES

Printer Mechanism

2.2.1  Carriage Mechanism

The Carriage mechanism consists of parts/units such as the Carriage Motor (CR 
Motor), Carriage Shafts, Platen Gap Adjustment Mechanism and Carriage Lock 
Mechanism.

2.2.1.1  Carriage Mechanism

The following indicates the specifications of the CR motor (DC motor) that drives the 
Carriage.

Closed loop control based on the CR Motor (DC Motor) and CR Encoder Sensor has 
advantages in stabilized print quality and silent operation.

†

Heat Generation Control
The printer has a mechanism to reduce the variations in the torque constant and 
coil resistance of the DC motors, and variations in output voltage of the Power 
Supply Board to obtain a designated heating value. 

†

CR Variation Measurement Sequence
The variations mentioned above are measured in a CR variation measurement 
sequence when the CR mechanical load is in the initial status and saved into the 
EEPROM. According to the saved information, the printer controls the drive 
voltage to obtain a designated driving current. This minimizes the unit-to-unit 
variation.

†

CR Measurement Sequence
To set the appropriate drive current value according to the CR mechanical load, 
the mechanical load is measured in a CR measurement sequence and saved into 
the EEPROM at power-on or after replacing the Ink Cartridge(s). 

The above control and sequences correct the drive current value of the CR Motor 
according to not only the mechanical load but also the variations of the motors. In 
addition, the resultant CR drive current value is used to calculate a heating value, and 
when the specified heating value is reached, wait time is provided per CR path for 
printing.
