    • An image-forming apparatus is capable of performing a non-margin recording operation without a margin on a recording medium and providing a waiting time between a moment of termination of a movement of a carriage in one of opposite directions and a moment of initiation of a subsequent movement of the carriage in the other direction, if the non-margin recording operation is performed during the movement of the carriage in the above-indicated one direction. The carriage is moved in the other direction (returned) at a speed lower than that of the movement in the above-indicated one direction, so that the back surface of an edge portion (e.g., leading end portion) of the recording medium is protected from contamination with an ink mist produced from the ink droplets. The waiting time and the return speed of the carriage can be manually selected or changed by using an operator's control panel, so that the non-margin recording operation can be performed in a desired manner (in a high-image-quality mode or a high-speed mode).
    • 图像形成装置能够在记录介质上执行无裕度的无边缘记录操作,并且在相反方向中的一个方向上的滑架的移动终止时刻和提供一个等待时间之间提供等待时间 如果在滑架在上述一个方向的移动期间执行非余量记录操作,则滑架在另一个方向上的后续移动。 滑架以比上述一个方向的运动速度低的方式在另一方向(返回)移动,使得记录介质的边缘部分(例如,前端部分)的后表面被保护 从由墨滴产生的墨雾的污染。 可以通过使用操作者的控制面板手动选择或更改托架的等待时间和返回速度,从而可以以期望的方式(以高图像质量模式或高的方式)执行非余量记录操作 速度模式)。

    • When a print process is started, discharge speed of recording papers is first set to a first discharge speed set based on the case in which a recording paper receiving unit for placing recording papers is in a reference state. Then, when a record instruction is given for starting a process of recording images onto recording papers, it is determined whether or not the recording paper receiving unit is in the reference state. If it is determined that the recording paper receiving unit is in an extended state in which the recording paper receiving unit is extended from the reference state, the discharge speed of the recording papers is set to a second discharge speed that is faster than the first discharge speed. Then, following a paper feed operation and an image record operation, the recording papers are discharged according to the set discharge speed.
    • 当打印处理开始时,首先将记录纸的排出速度设定为基于用于放置记录纸的记录纸接收单元处于基准状态的情况设定的第一排出速度。 然后,当记录指令用于启动将记录图像记录在记录纸上的处理时,确定记录纸接收单元是否处于参考状态。 如果确定记录纸接收单元处于其中记录纸接收单元从基准状态延伸的伸展状态,则记录纸的排出速度被设定为比第一次放电更快的第二排出速度 速度。 然后,在进纸操作和图像记录操作之后,记录纸根据设定的排出速度排出。

    • In order to adjust a position of a cut sheet when the cut sheet begins to be sent to a printing positions a leading edge of the cut sheet is fed towards a pair of sending rollers for sending the cut sheet to a printing position, wherein the sending rollers are held at rest or rotated in reverse. If a predetermined condition is satisfied, a feeding speed of the cut sheet decreases when the leading edge of the cut sheet reaches a position that is a predetermined distance upstream of the sending rollers. If the predetermined condition is not satisfied, the feeding speed of the cut sheet does not decrease before the leading edge of the cut sheet contacts the sending roller. A decline in printing quality and an unnecessary delay in printing time can be prevented. With the sending rollers, an effect to prevent the leading edge of the cut sheet from being fed in a slanted position is also maintained.
    • 为了在裁切纸开始发送到打印位置时调节裁切纸的位置,将切割的纸张的前端朝向一对送纸辊送出,以便将裁切的纸张发送到打印位置,其中发送 滚轮保持静止或反向旋转。 如果满足预定条件,则当切割的片材的前缘到达发送辊上游的预定距离的位置时,切割片材的进给速度降低。 如果不满足预定条件,则在切割的片材的前缘接触送纸辊之前,切割片材的进给速度不会降低。 可以防止打印质量的下降和打印时间的不必要的延迟。 对于送纸辊,还保持了防止切割片材的前缘进入倾斜位置的效果。
