图像形成设备、从记录头的喷嘴吸引液体的方法和计算机可读信息记录介质
摘要：
一种图像形成设备包括记录头，所述记录头被配置成具有喷嘴表面，在所述喷嘴表面上形成排出液滴的喷嘴；盖，所述盖被配置成覆盖所述记录头的所述喷嘴表面；排出路径，所述排出路径被配置成被连接到所述盖；吸引泵，所述吸引泵被配置成被设置在所述排出路径中并且由管泵制成；和大气开放部，所述大气开放部被配置成将当所述喷嘴表面被所述盖覆盖时建立的密闭空间开放到大气。所述大气开放部被配置成在比排出到所述盖中的液体的表面更高的位置处与所述盖的内侧相连通，并且配置成防止所述液体从所述吸引泵朝着所述盖的流动的止回阀被设置在所述排出路径中。
摘要（英）：

An image forming apparatus includes a recording head configured to have a nozzle face on which nozzles that discharge liquid droplets are formed, a cap configured to cap the nozzle face of the recording head, a discharge path configured to be connected to the cap, a suction pump configured to be provided in the discharge path and be made of a tube pump, and an atmosphere opening part configured to open an airtight space, created when the nozzle face is capped by the cap, to the atmosphere. The atmosphere opening part is configured to communicate with the inside of the cap at a position higher than a surface of liquid discharged into the cap, and a check valve configured to prevent a flow of the liquid toward the cap from the suction pump is provided in the discharge path.
