3-1. Ink Drop Position Enhancement Adjustment

<Adjustment Overview>
The particular unevenness of the transfer belt along with vibration and eccentricity of transfer rollers causes
inconsistency in ink droplet position. However, the precision of ink droplet positioning can be enhanced by
controlling the timing of ejection to compensate for these factors.
