    • 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).

    • 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。
