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.

摘要： A method for sensing separation of a carriage from a home position and compensating the home position by using a program stored at a microprocessor of an ink jet printer includes a home position separation sensing process which has the steps of: checking whether or not the ink jet printer is in a stop state and the carriage is placed at the home position; checking whether or not the carriage placed at the home position is separated from the position by sensing the state change of a photo sensor; and setting a flag according to the state change of the photo sensor, and a home position separation state compensating process which has the steps of: checking whether or not a flag has been set; if it is checked that the flag has been set, counting time to maintain the present state for a predetermined time; resetting the home position if the counted time exceeds the predetermined time; checking whether or not an ink cartridge is attached to the carriage; if it is checked that the ink cartridge is attached to the carriage, compensating the position of the carriage tocorresponds to the reset home position; and after completion of the compensating step, clearing all related flags.
摘要翻译：一种用于感测滑架与原始位置的分离并通过使用存储在喷墨打印机的微处理器处的程序来补偿原始位置的方法包括原位分离感测处理，其具有以下步骤：检查喷墨打印机处于停止状态，托架位于原位置; 通过感测光传感器的状态变化来检查放置在原位置的滑架是否与位置分离; 以及根据光传感器的状态变化设置标志，以及原点位置分离状态补偿处理，其具有以下步骤：检查是否已经设置了标志; 如果检查到已经设置了标志，则计算时间以将当前状态保持预定时间; 如果计时的时间超过预定时间，则重置起始位置; 检查墨盒是否连接到托架上; 如果检查墨盒是否安装在托架上，则补偿托架的位置对应于复位原位; 在完成补偿步骤后，清除所有相关标志。

摘要： A method for correcting scanning errors in a shuttle type of a scanner, including the steps of scanning a pattern sheet on which pattern data having a specified shape are recorded. Errors for decline of the pattern data are corrected by using the pattern data having a straight line among the scanned pattern data having the specified shape. Then, errors for distance between bands are corrected by using the pattern data having the specified shape among the pattern data of which the errors for decline are corrected. Accordingly, since the errors for decline and the errors for distance between the bands can be corrected by using a computing program, there is an advantage in that correcting the errors of the pattern data is very simple. A further advantage is in that even if the scanner is subjected to an impact from its exterior, correcting the errors for decline and the errors for distance between the bands can be promptly performed.
