Image forming apparatus that makes FPOT (first print out time) appropriate in accordance with time taken to expand image information and to reduce deterioration of consumable items
Abstract:
When a pre-rotation sequence is started at a time at which a print-start notification command is transmitted, in the case where a predicted time period is longer than a time period taken to perform the pre-rotation sequence, an appropriate FPOT is not realized. To determine whether the pre-rotation sequence can be started at a time at which a print reservation command that is to be transmitted before transmission of the print-start notification command is transmitted to the engine, a drum-rotation permission command is provided, whereby, in the case of immediately starting the pre-rotation sequence, the pre-rotation sequence can be started earlier than the pre-rotation sequence is started, reducing the FPOT. In the case of not immediately starting the pre-rotation sequence, a time period taken to perform image expansion and the time period taken to perform the pre-rotation sequence can be made to coincide with each other, reducing consumable items deterioration.
Abstract(Chinese):

当在发送打印开始通知命令的时刻开始预旋转顺序时，在预测时间长于执行预旋转顺序所花费的时间段的情况下，适当的FPOT不是 实现了 为了确定是否可以在将发送打印开始通知命令之前要发送的打印预约命令发送到发动机的时刻开始预旋转顺序，提供滚筒旋转允许命令，由此 在立即开始预旋转顺序的情况下，可以比预旋转顺序开始更早地开始预旋转顺序，从而减少FPOT。 在没有立即开始预旋转顺序的情况下，可以使执行图像展开所需的时间段和执行预旋转顺序所用的时间段彼此一致，从而减少了消耗品的劣化。
