Title:
インクジェット記録装置及びキャリッジ制御方法
Document Type and Number:
Japanese Patent JP5649401
Kind Code:
B2
Abstract:
A carriage is precisely controlled in short-distance movement. The carriage is controlled upon printing by an inkjet printhead by reciprocally moving the carriage to which the printhead is mounted along a guide rail by a driving force supplied from a carriage motor. More specifically, a carriage position in the reciprocal direction is detected, and a carriage speed is calculated based on the detected positions. Then, the positions and carriage speed are fed back to control drive of the carriage motor. In the feedback-control, a loss due to friction generated between the carriage and the guide rail is compensated for with respect to a motor instruction value used to control drive of the carriage motor. The compensation is performed by identifying, based on the carriage speed, whether the friction is static or kinetic, and determining a compensation value in accordance with the identification.
