摘要： A printer includes an ink head including a nozzle surface including nozzles, a cap including an end portion contactable with the nozzle surface, a suction device, a memory, and a controller. The memory stores a suction position, a free suction position, and a minute open position located between the suction position and the free suction position. The controller performs a suction process in which the cap is located at the suction position and ink is sucked from the nozzles, and a minute open position process in which the cap is moved toward a minute open position and movement of the cap is stopped with the cap located at a minute open position, after the suction process.

摘要： An inkjet printer includes a first ink head, an ink collector, and an intermittent flushing controller. The first ink head includes a first sub-head that includes a first nozzle to discharge first ink, a second sub-head that includes a second nozzle to discharge second ink different from the first ink, and a nozzle surface provided with the first nozzle and the second nozzle. The ink collector collects the ink discharged from the first ink head. The intermittent flushing controller performs an intermittent flushing operation for at least the first sub-head. The intermittent flushing operation involves repeating a first operation and a second operation for a predetermined number of iterations. The first operation involves discharging the first ink into the ink collector from the first nozzle a predetermined number of times. The second operation involves being on standby for a predetermined time without discharging the first ink from the first nozzle.
