2.2.1  Carriage Mechanism

The Carriage mechanism consists of the Carriage Motor (CR Motor), Carriage 
Shafts, Platen Gap Adjustment Mechanism, Carriage Lock Mechanism, and 
others.

2.2.1.1  Carriage Mechanism

The following indicates the Carriage driving DC motor specifications.

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
Using low-cost DC motors, this product grasps the variations of the torque 
constants, coil resistances and power supply board output voltages of the 
individual DC motors adequately to carry out heat generation control 
according to individual differences.

†

CR variation measurement sequence
The variations of the torque constant, coil resistance and power supply 
board output voltage of the motor are measured in a CR variation 
measurement sequence when the CR mechanical load is in the initial 
status and saved into the EEPROM (A6<H>). According to the variations 
(individual differences) measured in this sequence, the voltage is corrected 
to make the drive current value constant (without an individual difference) 
according to the variations (individual differences) measured in this 
sequence.

†

CR measurement sequence
To set the appropriate drive current value according to the variation of the 
CR mechanical load, the mechanical load is measured in a CR 
measurement sequence and saved into the EEPROM A4<H>, A5<H> in a 
power-on or IC change sequence. However, if 46 is saved at the EEPROM 
A4<H> and 05 at A5<H>, Fatal error will occur since too large load is 
applied to the CR drive system.

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 
motor and like. 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.
