当我按下绿色的复印按钮时，左下角三个指示灯中最左侧的灯由常绿变为绿色闪烁，过了一会儿由变为常绿。复印机未作出任何反应。 复印失败。 When I pressed the green copy button, the leftmost of the three lights in the lower left corner changed from constant green to flashing green, and then to constant green again after a while. The printer gave no further response. The copy function does not work!
