    • A head maintenance control method of an inkjet printer includes receiving a printing command performing a printing operation, calculating a time difference between an input time of the printing command and a final time that the printing operation of the inkjet printer has been most recently performed before the printing command is input, displaying a message requesting the maintenance operation when the time difference is greater than a predetermined time, and performing the maintenance when an execution command for performing the maintenance is input. An intensity of the maintenance operation varies in accordance with the time difference. The maintenance operation is performed in response to an actually required degree when the maintenance should be performed, thus an unnecessary maintenance operation is avoided or an incomplete maintenance operation is prevented. Furthermore, the message requesting the maintenance is informed to the user, thus the user can easily recognize that the maintenance operation is needed and also the user can operate the maintenance operation voluntarily.
    • 喷墨打印机的头部维护控制方法包括接收执行打印操作的打印命令,计算打印命令的输入时间与喷墨打印机的打印操作最近在最前执行的最后时间之间的时间差 输入打印命令,当时间差大于预定时间时显示请求维护操作的消息,并且在输入用于执行维护的执行命令时进行维护。 维护操作的强度根据时间差而变化。 在执行维护时,根据实际需要的程度进行维护操作,从而避免不必要的维护操作或者防止不完备的维护操作。 此外,向用户通知请求维护的消息,因此用户可以容易地认识到需要维护操作,并且用户也可以自愿地操作维护操作。
