Apparatus and method for determining initial position and protecting capping release error in inkjet printer head

摘要

An apparatus for determining an initial position and protecting a capping release error in an inkjet printer head which can constitute a sensor for determining a printing initial position and a device for preventing a capping state from being released during the head is at a homestation, with a single sensor and two actuators. The apparatus includes a home sensor arranged in a frame, for sensing the initial position and the capping release error of a carriage to transmit a sensing signal to a controller, a first actuator disposed in a right side of the carriage, for sensing an initial position of the carriage in which a head is mounted to perform a printing operation in a print interval, when power in the printer is turned on or a printing command is issued, and a second actuator disposed in a left side of the carriage and passing the home sensor, for maintaining a state where a cap is capped on a nozzle of the head after the carriage is moved to a service interval and for controlling a position of the carriage, to thereby prevent a capping state from being released.
